v0.37, 17-SEP-2012:

fix: changes made to multi-value floats as used in HLSL options weren't updated correctly
fix: demo-mode: don't select device-sets
fix: non-Windows: avoid a rare crash when exiting QMC2 while a running emulator is producing output on the notifier FIFO
fix: don't allow tagging/untagging of parent-items in category- and version-views
fix: file-browsers in emulator configuration dialogs used the wrong standard file-dialog so non-existing file names weren't accepted
fix: ZIP-archived image files weren't correctly opened initially
fix: full-screen switching on Ubuntu 12.04 (Unity desktop) didn't work correctly -- see bug tracker ID #26
fix: don't pass empty arguments when launching foreign emulators
fix: non-Windows: the optional memory indicator wasn't updated because the corresponding timer didn't fire
fix: MESS device configurator: when a configuration made with the file-chooser was saved, the current slot setup wasn't stored together with it -- rendering the stored item useless when slot customizations were required
fix: corrected ROM status determination for sets containing only CHDs (but no ROMs)
fix: the current emulator selection made on the game/machine-specific configuration tab wasn't saved upon reload
fix: minor: corrected progress-text updates when certain operations are running 'in parallel' (i.e. loading the software-list while a full ROM audit is active)
fix: avoid crash when no game/machine is selected and a 'play' action is triggered
fix: MiniWebBrowser: corrected document history handling with regard to the availability of back- and forward-actions
fix: set locale- and c-string-encoding to UTF-8 globally and handle XML data specifically on Windows to cleanly support international character sets
fix: emulator wasn't launched under certain circumstances when the game/machine was filtered out due to its ROM status
fix: use UTF-8 character encoding when reading game-/machine- and/or emulator-info DB dat-sources
imp: adjusted the ghost-image used for videos (wrong text removed)
imp: depending on the installed codecs, an unused YouTube widget may still cause load on the system, so it's now already destroyed when it's no longer required
imp: updated redistributed Qt translations from Qt 4.8.3
imp: unified the image processing to remove code duplication for different image types
imp: check for the existence of the emulator's executable file before trying to actually run a null process (which may cause issues on Mac OS X)
imp: Mac OS X build: added build option XCODE3 which (if set to 1) will disable the special handling when Qt 4.8+ is detected
imp: MAME/MESS/UME emulator templates updated to 0.147 (added new core options ui_mouse and ui_active, removed option hide_cursor)
imp: added an option to allow for setting QMC2's working directory to be the same as the executable's path (for special use cases, not commonly used)
imp: replaced all QMC2 variant logos and splash-screens with improved versions from JacKc
imp: Qt messages that are sent before the GUI is ready are now printed to the console (stdout) instead of eating them
imp: emulator configuration widgets: all drop-down lists for 'bios' / 'ramsize' selections or options with pre-defined choices are now sorted, possible duplicates are removed and the number of visible items has been increased to 20
imp: the file-chooser's folder selector is now also sorted / sortable
imp: foreign emulator IDs can now contain arguments with white-space characters when they are enclosed in double-quotes
imp: changed the file-chooser's sorting (by file name) to be case-insensitive
imp: updated template format to v0.2.6 which adds support to ignore complete sections (globally or per target OS)
imp: Mac OS X build: don't compile runonce as it's not used on Mac OS X (and has an X11 requirement)
imp: integrated zlib updated to version 1.2.7 (see zlib's change-log for details)
imp: Win32 MinGW build: added OS auto-detection for Windows so specification of MINGW=1 is no longer required (however, if MINGW is set, its value will be used regardless)
imp: when a non-default (= foreign) emulator is selected for the current game/machine, the device-mapper and software-list tabs are disabled now
imp: sets with empty names are now ignored, logging corresponding warnings when the game/machine list cache is recreated (this is a driver bug which also '-validate' will warn about)
imp: Win32 VC++ build: added x64 support to the project generation script
imp: added an advanced line-edit containing an icon to symbolize its function (used in certain search widgets)
imp: changed the default short-cuts for adding games/machines to the favorites list (now Ctrl+J and Ctrl+Shift+J) to free the Ctrl+F short-cut for another/better use (i.e. for finding arbitrary text)
imp: changed the default short-cut for 'About QMC2' (now Ctrl+B) to free the Ctrl+A short-cut which is commonly used for 'select all'
imp: file-chooser: opened ZIP contents are sorted as well
imp: completely revised the image cache internals, now also storing the file path the cached image was loaded from, which can be retrieved via the image's context-menu (the file path is not available in case of zipped images, though)
imp: much better GUI response while recreating the XML cache and checking all ROMs (full audit)
imp: animate searching for game/machine XML data when the user expands an item in the primary (full-detail) view
imp: the menu-bar on Mac OS X is no longer 'native' because this misbehaves with multiple menu-bars that we have now
imp: emulator configuration widgets are now initially hidden and shown after all options were loaded, which speeds up this process a little bit (you won't see a visual difference, though)
imp: added OS detection for Windows 8 and Mac OS X 10.8 to the about dialog when Qt 4.8.3 or higher is used
new: added support for David Haywood's (Haze) Universal Machine Emulator (MAME/MESS unification project) in the form of an additional variant called 'qmc2-ume' or 'qmc2-sdlume' -- see bug tracker ID #22
new: the YouTube video-player now supports local movie files as well
new: added support for tool-bar customization
new: allow the specification of semicolon-separated lists of folders for ALL image types
new: added support for system- and manufacturer-logo images (i. e. AntoPISA's new MESS marquees)
new: added support for the new MESS category.ini from ASH (UME targets merge the info with data from catver.ini, if applicable)
new: added a check for the ROM path setting (a warning message will pop up when the ROM path hasn't been set or isn't available) -- see bug tracker ID #28
new: made a complete rewrite of the image-checker dialog, which now allows checks of ALL image types in a multi-threaded way -- this also fixes a long-standing bug on Windows, BTW (see bug tracker ID #5)
new: MESS device configurator: added support for nested slots, including real slot recursion
new: software-lists: available mount-devices are dynamically updated whenever the device/slot setup changes
new: added 3 new actions to tag / untag / invert tags of all visible sets (according to the current ROM state filter)
new: game/machine detail tabs can now also be reordered directly in the GUI by dragging them with the mouse
new: added a tool action to open a new empty browser window on demand
new: <info> elements contained in a number of software-list entries are now displayed as well (requires very recent MAME/MESS/UME versions after 0.146u5, otherwise <info> elements are not contained in the -listsoftware output)
new: items in all game/machine list views can now be tagged/untagged while the 'cursor' is moved, using the new (customizable) short-cuts Shift+Up and Shift+Down (works much like in 'Total Commander' when tagging/untagging files or folders)
new: the file-chooser now offers an additional context-menu item to open regular files (not ZIP content yet!) externally by launching the default application that's associated with the file's MIME type (or extension)
new: added a 'personal rich-text notes' detail for games/machines (same as the software-notes feature, but for systems this time)
new: added command line option '-cc' which clears (removes) all emulator caches prior to starting up
new: HTML editor: added document preview in built-in browser as well as 'new-from-template' and 'revert-from-saved-file' functionality
new: MESS device configurator: added support for selecting the BIOS used in slot-devices (if applicable)
new: software-lists: optional automatic adjustment of the emulator's -snapname parameter for easier creation of software-snapshots
doc: use a common image directory instead of sym-links
inf: the configuration template for MAMEUIFX32 has been dropped (unmaintained)
inf: long project name changed to M.A.M.E./M.E.S.S./U.M.E. Catalog / Launcher II

v0.36, 21-MAY-2012:

fix: ROMAlyzer: don't stop searching for CHDs at the first ROM path (when there are multiple ROM paths)
fix: allow embedding of (MAME/MESS-like) foreign emulators again -- changes made in 0.35 prevented this completely
fix: changed the default short-cut for the check template map action to 'Ctrl+Shift+C' -- the previous default of 'Ctrl+C' was awkward since it's usually used as short-cut for copy to clipboard
fix: avoid crashes in the game list parser and the ROMAlyzer's checksum wizard due to unexpected nameless entries (first appeared in MESS 0.145u1+)
fix: build: corrected a new set of compile-time bugs related to builds with PHONON=0
fix: ROMAlyzer: after updating CHDs to the latest format, update the CHD header information from the replaced file before comparing the SHA1 checksums
fix: minor: corrected a few texts with regard to the current variant's emulator type (MAME vs. MESS)
fix: file-chooser: expand/collapse ZIP-contents on any type of 'activation' (i.e. not only on mouse double-clicks but also when enter or return are pressed, includes navigation via cursor-keys)
fix: re-enable 'locked' widgets when the emulator can't be started for reading the game/machine data
fix: MESS device configurator: corrected display of file-editor's data when there's only one available device instance (by synchronizing delegate/model updates)
fix: don't start a verification process when the ROM state cache can't be opened for writing
fix: file-chooser: the machine-dependent software-folder was not correctly pre-selected when existing device configurations were loaded in parallel
fix: MESS device configurator: avoid a rare crash when systems are hovered very quickly (asynchronous updates may otherwise work on meanwhile invalid data)
fix: clear favorites and play-history upon reload and make sure the last selected game/machine is correctly re-selected (if applicable)
fix: ROMAlyzer: when repairing a set and the wanted CRC or name (header-)entry already exists in the target ZIP, recreate the complete ZIP file in order to replace the 'bad' file
fix: ROMAlyzer: don't rewrite sets that are analyzed on behalf of the checksum-wizard (even if 'rewrite while analyzing' has been activated)
fix: corrected some additional MESS-specific phrases and removed WIP-only stuff from key- & joystick-mappers
fix: adjusted the behavior of the two main search combo-boxes and tied them more closely
fix: software-lists: support multiple allowed device-interface types
fix: MiniWebBrowser: don't raise main-widget / lower browser window(s) when selecting the path to save a downloadable resource
fix: corrected character conversion when compressing HTML data stored in in-memory and on-disk web-caches (using QString::toLocal8Bit() instead of QString::toLatin1() now)
imp: ROMAlyzer: LRU-caching XML data positions in order to speed up merge-processing
imp: updated the MAME variant's logo with an improved version from JacKc
imp: MESS device configurator: log a warning when '-listslots' crashes
imp: MAME/MESS emulator templates updated to 0.146 (fixed duplication of option 'natural' in MESS templates)
imp: interpret the new 'has no roms' status as 'good' (a.k.a. correct)
imp: foreign emulator support: added $DESCRIPTION$ as an optional argument placeholder for the set's description
imp: ROMAlyzer: interpret emu- and file-states of sets that have no ROMs as 'good' also in case of MAME (new since 0.145u2)
imp: ROM status check: circumvent the corner case of sets without ROMs also in case of MAME (new since 0.145u2, see 'ide_baseboard' and 'hdd' devices)
imp: ROMAlyzer: log possible driver XML bugs where a merge-name is given without a parent set to take it from (other than this, these cases are ignored and treated as 'good' merge-states)
imp: when registering foreign emulators, the existence of the $ID$ placeholder on the supplied command line is now indicated through a green/yellow colored label (when $ID$ is missing, the configuration will most likely not work)
imp: allow the specification of the emulator's working directory already in the welcome dialog
imp: updated redistributed Qt translations from Qt 4.8.1
imp: honor 'players' value for device sets where applicable (i.e. some input devices)
imp: MESS device configurator: sort slot-options alphanumerically, add a separator between 'not used' and available options, allow disabling of default slot-options and indicate them as such
imp: main widget: revised all auto-connected menu actions to use QAction::triggered(bool) (instead of a meanwhile deprecated signal)
imp: slightly better responsiveness while loading cached XML data
imp: Mac OS X build: avoid using xcodebuild for Qt 4.8+
imp: replaced the 'MESS wiki driver look-up' with a ProjectMESS-based search since most data in the MESS wiki was lost, and ProjectMESS is the new de-facto '#1 web-resource for all things MESS' :)
imp: the MiniWebBrowser's zoom-factor can now also be specified through a (mouse) wheel-event when the Ctrl-key is pressed at the same time (like most standalone browsers)
new: ROMAlyzer: added support for CHD v5 (new since MAME/MESS 0.145u1) -- built-in analysis will work for CHD v3, v4 and v5; however, note that all 'CHD manager' functionality requires chdman from MAME/MESS 0.145u1+ now
new: ROMAlyzer: added a function to store the current log contents to a file
new: added tear-off capability to all menus within menu-bars
new: added freely customizable lists of game/machine IDs (and descriptions) that can be attached to foreign emulators and be presented / launched through the menu
new: both the MAWS (off-line) and the ProjectMESS driver look-up features save/restore their zoom-factors now
new: experimental support for Qt 5, which is in alpha-stage right now (there will be no embedder support on X11 platforms in the first place, since they dropped some X11-specific classes like the QX11EmbedContainer -- an add-on for Qt 5 to revive this functionality is planned, but will probably not be available before Qt 5.1)
new: YouTube video-player: you can now also 'paste' a YouTube video URL into the video-player itself, which will then start playing the respective video without attaching it to the play list
new: about dialog: added output of run-time Qt library paths to the system-information page
new: integrated zlib 1.2.6 to remove the extra requirement
new: the MiniWebBrowser now supports and allows pop-up window requests when the build option BROWSER_JAVASCRIPT is enabled (which is the default)
new: build option BROWSER_EXTRAS is now enabled by default which also activates the use of QtWebKit's Web Inspector in the MiniWebBrowser for everyone
new: added a Spanish translation -- thanks to Daniel Barrado
wip: adding a set rename tool to the ROMAlyzer which uses the -listxml outputs from both the old and the current emulator to gather the changes automagically
wip: adding a Romanian translation (mostly done) -- thanks to Mihai Boisteanu
wip: adding an Italian translation -- thanks to Stefano Cereda
wip: adding a stand-alone CHDMAN GUI (see tools/qchdman/)
wip: adding a Greek translation -- thanks to Kostas Albanidis
wip: adding a Swedish translation -- thanks to Daniel Nylander

v0.35, 06-FEB-2012:

fix: minor: hide the software-list favorites column 'device configuration' for MAME targets as it's a MESS-only feature
fix: minor: corrected the main progress-bar's visual behavior when ROM status checking and software-list caching are running in parallel
fix: MAME targets: the software-list widget wasn't cleared upon reload
fix: the last active detail-tab's header wasn't always shown initially
fix: software-snapshots were positioned incorrectly under certain circumstances
fix: corrected a few minor log-scrolling issues
fix: individual ROM checks didn't work correctly when the ROM status was 'not found' since output is written to stderr in this case and not to stdout as otherwise
fix: YouTube video-player: avoid crashes on exit by waiting for all application threads to finish before returning to the OS
fix: YouTube video-player: attached videos could get lost when changing the current game/machine very quickly
fix: ROMAlyzer: correctly 'remove' the progress-bar item-widget before deleting it (worked w/o until Qt 4.7.x, crashed since Qt 4.8.0)
fix: corrected restoration of main-widget's layout when the front-end was showing a maximized embedded emulator during clean up on the previous run
fix: corrected Windows 64-bit builds with DEBUG=2 (see bug tracker ID #21)
fix: file-chooser: the underlying item model now produces correct minimum widths for icon-less columns (size and modification date)
fix: embedder on X11: corrected initial input focus after launching a new embedded emulator
imp: ROM status exporter: additional output-format choice ('all formats') to export the ROM states to all three formats at once
imp: when a software-list can't be found (though it's expected to exist), leave the software-list widget disabled and don't try to parse the invalid XML (a warning will still be logged since this is actually an emulator bug, but probably also a wanted/known situation as told by etabeta78)
imp: MAME/MESS emulator templates updated to 0.145
imp: faster display of software-snapshots by using tool-tip like window attributes for the viewer widget (this also fixes bad-window errors on X11)
imp: slightly bigger icons in all game/machine list views
imp: updated template format to v0.2.5 which adds support for an optional 'part' attribute that can be used in file-type options to specify the extracted part of the file's path (currently only "basename" is supported, used by the effect-option)
imp: loading of software-lists can be interrupted now and is indicated accordingly for larger lists (i.e. cpc_cass/cpc_flop)
imp: Mac OS X build: moved macx/Info.plist.in to arch/Darwin/Info.plist.in where it belongs
imp: build: added a 'configure' make target to create platform dependent project file(s) and stop (i.e. to open it in XCode and build from there on Mac OS X, or to run MinGW make in job-server mode on Windows)
imp: MiniWebBrowser: browser-plugins are now enabled per default (see make option BROWSER_PLUGINS)
imp: build: removed make option PRETTY as it's no longer usable in the supported Qt versions
imp: Mac OS X build: provide application icons (.icns) to be associated with the apps
imp: created new logo images (thanks to JacKc)
imp: ROMAlyzer: checksum-wizard: when the user changes the checksum-type and the current checksum is available in the 'other' type as well, display it in the line-edit (not available when the checksum is edited manually)
new: the ROM state filtering mechanism can now be enabled/disabled on-the-fly (the default is 'enabled', just as before)
new: added support for multi-device software-list entries as well as automatic vs. manual mount-device selection (includes the ability to mix parts from different software-list entries)
new: added an alternative game/machine search entry box to the tool-bar
new: added a CSV and ASCII export tool for software-lists
new: added import/export functionality for software-list favorites
new: changed the MESS device configurator so it offers available device-instances based on the slot-options specified, thus allowing to mount them as well (through the legacy device-mapper and the file-chooser)
new: added ZIP support for software-snapshots
new: X11 and Windows only: game/machine icons are now also shown on the tab headers of embedded emulators
new: all images have an additional context-menu item ('refresh') now to clear and reload their cached pendants
new: integrated the HTML editor from Qt Labs / graphics-dojo for all kinds of (upcoming) rich-text editing purposes
new: added content-zoom to the MiniWebBrowser
new: top-level windows can now optionally be minimized upon emulation launch and automatically restored when the (last) emulator instance has ended
new: YouTube video-player: added a semi-transparent overlay widget to display status information at the bottom of the player's viewport
new: software-lists: added software-compatibility filtering
new: added a 'MESS wiki' detail to look up available driver information
new: added an option to suppress all messages sent through QDebug and related convenience functions
new: added an optional startup splash-screen utilizing the new logos
new: added support for emulator-embedding on Windows (!) -- note, however, that embedding of emulators running in Direct 3D mode ('-video d3d') has two known issues: full-screen switching will lead to a crash (of the emulator) and screen-shots aren't taken correctly from within the GUI (just a black image)
new: X11 and Windows only: added an option to select the default launch-mode used when starting emulation by activating (i.e. double-clicking) an entry in any list
new: X11 and Windows only: replaced the style-controlled embedder-release icons (usually a red 'X' which some users wrongly interpreted as 'exit emulator') with a more suitable / less irritating and style-independent icon by setting explicit style-sheets on the tab-bars of all embedders
new: added two options to allow for hiding of BIOS and/or device sets in all master-lists (see Front end -> Game/Machine list in the main setup dialog) -- both will trigger an automatic reload when changed
new: added a dock-able/floating software-detail widget with a separate snapshot-browser, a ProjectMESS software-lookup feature, and an HTML editor/viewer for personal rich-text software-notes
inf: the new required minimum Qt version is 4.7.0, support for older versions of Qt has been dropped

v0.34, 15-NOV-2011:

fix: MAME targets: don't auto-resize the last column in the game/machine list views when toggling the use of catver.ini (it annoys more than it helps)
fix: build: corrected compile-time bugs related to builds with PHONON=0
fix: adjust icon sizes when showing the audio-effect dialog initially
fix: removed flicker on changing game-/machine-list views
fix: corrected a few MESS-specific phrases
fix: corrected delegate-sizing issues when there's only one device instance in the MESS device setup
fix: Mac OS X: set ROMAlyzer's parent widget in order to avoid context-menu displacement
fix: ROMAlyzer: the ROM set's context-menu should be available also when the set rewriter hasn't been enabled
fix: MAME targets: category- and version-views were not created initially when switched to via the view-selector combo-box
fix: MAME targets: demo-mode: avoid floating-point exception when no games were selected by the filter
imp: updated minizip to version 1.01h
imp: YouTube video player: decode (percent-)encoded error messages before logging them
imp: setup dialog: conflated all formerly split emulator- and game-info DB settings
imp: MAME/MESS emulator templates updated to 0.144
imp: ROMAlyzer: better 'no dump' indication
imp: enabled audio-effect widgets for MinGW builds (they work fine when the official Qt DLLs are being used, otherwise set the new AUDIOEFFECTDIALOGS make option to 0 in order to disable them)
imp: X11 only: minor embedder optimizations regarding widget resizing
imp: YouTube video player: added support for YouTube's new way of presenting video stream URLs
imp: general overhaul of the main-widget's layout parameters to allow for a somewhat more 'compact' design
imp: the working directory of the external ROM tool can be specified now
imp: build: added EMU as an alias for the EMULATOR make option
imp: locale-aware statistics in the ROM status exporter and the GUI's ROM status bar
imp: updated redistributed Qt translations from Qt 4.7.4
new: added a 'driver status' column to all game/machine lists (or views)
new: Windows only: the other variant's exe file can now be specified explicitly (the default is to search for it only in the directory where the calling variant was started from) -- this works also when you rename the exe files; you can additionally specify the command line arguments passed to the other variant (note that this is an independent setting and would also be used when the variant exe is not overwritten!)
new: support for MAME's/MESS's new device-referencing (new since 0.143u2+ SVN)
new: Mac OS X only: the tool-bar can now optionally be unified with the title-bar
new: MESS targets: support for machine-specific device slots / slot options, integrated with the MESS device configurator
new: the MESS variants now use their own logo, and all variants use new unified applications icons -- thanks to Anna Wu
new: added a new tool-function to allow for forced removal of ALL emulator related caches at once
new: added support for the new 'messinfo.dat' file from AntoPISA (see http://www.progettosnaps.net/messinfo/)
new: completed the support for software-lists in MAME and MESS (ZIP-support for software-snaps will be added later)
new: customizable columns in all game-/machine-list and software-list views
new: MESS targets: a new 'file chooser' dialog has been added to the MESS device configurator as an easy-to-use alternative to the manual setup
new: MESS targets: device type icons are now displayed to better symbolize MESS device instances
new: ROMAlyzer: you can specify an additional source ROM path for the set rewriter in order to allow for merging updates
new: added support for item-tagging and a number of related operations that can now also be performed for tagged games/machines
new: for ZIP-archived icons (actually the only practical way to store them) support for ICO format has been added -- this means that for instance MAMU's icon can now be used directly, w/o conversion to PNGs!
new: icons are now also supported for all MESS targets
wip: adding a Java (Eclipse/SWT) based editor/translator for emulator templates (see tools/qmc2_options_editor_java) -- thanks to Marcelo Bossoni
inf: note that the versioning pattern has changed: we now just count the releases and follow the simple scheme '0.XX', where XX is the release number
inf: note that the minimum required MESS revision now is SVN r12599 (or MESS 0.143u3)

v0.2.b20, 29-JUN-2011:

fix: ROMAlyzer / checksum wizard: correctly handle ROM files when their names contain special characters (i.e. '&')
fix: corrected the handling of repeated log messages (the repetition counter was correctly logged, but the actual new message was eaten)
fix: remove Phonon effects asynchronously (aka QObject::deleteLater()) -- note that this finally also fixes the long-standing post-mortem crash on Mac OS X
fix: file and directory edit widgets did only commit any data changes when they were 'edited', but not when their data changed 'spontaneously' -- see bug tracker ID #17
fix: MESS targets: avoid crash when exiting while a device setup is open
fix: emulator configuration: correctly position the text cursor for 'int' and 'float' option types as well
fix: corrected hiding of category-/version-columns in the category-/version-views
fix: embedder: under certain window-managers (i.e. KDE4 >= 4.6) the snapshot-viewer wasn't correctly updated -- fixed by adding an explicit paintEvent() method which just repaints the background brush
fix: Win32: emulator control panel: hide LED0-, LED1- and status-columns, because notifiers aren't supported on Windows (yet)
fix: build: corrected the default image directory settings used for /etc/qmc2/qmc2.ini during installation (see inst/qmc2.ini.template)
fix: minor: put arguments containing white-space characters in double-quotes when presenting/copying the emulator command line
fix: log file paths weren't correctly set up on the initial run, so logs were written only on subsequent runs
fix: corrected a rather old bug within the game/machine-list cache creation code that could've led to rare (and hard to reproduce) crashes
fix: ROM status exporter: CSV and HTML output formats didn't honor the specified ROM status filter
fix: ROMAlyzer: corrected (minor) overflow issues caused by using plural-translation with large unsigned numbers (Qt only supports this cleanly for signed integers)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.143 (new option menu for MAME, removed option uimodekey for MAME, changed default value of audio_latency for SDLMAME, added new options use_cpanels, use_marquees and confirm_quit for all, added many new HLSL options for MAME)
imp: SDLMESS/MESS templates updated to 0.143 (changed default value of audio_latency for SDLMESS, added new options use_cpanels, use_marquees and confirm_quit for all, added many new HLSL options for MESS)
imp: ghost image enhanced, including a derived 'no video' pendant
imp: improved log output when the validation of the emulator executable fails
imp: MESS targets: added new / alternate emulator type identification string ('M.E.S.S.' vs. 'MESS') as used since 0.142 SVN -- see bug tracker ID #16
imp: MESS targets: the device configurator now also saves / restores the last selected setup (if any) and includes a context menu for the device instance map
imp: added an option to let the user decide if the ROM status icons are to be shown or not (see in game/machine-list tab of the main setup dialog)
imp: avoid potential blocking when synchronously calling external programs
imp: updated template format to v0.2.4 which adds support for a new 'combo' option-type (editable combo-box with pre-defined choices the user can select from), a new 'visible' attribute to hide certain options (esp. to hide the ramsize option for MAME, where it's not used, but the emulator still reports it as a valid option), two additional option types ('float2', 'float3') for multi-part floating point values and an optional decimals attribute for all float types to specify the precision (default precision: '6 decimals')
imp: setup dialog: added the ability to reset a customized application- or log-font as well as to reset the style-sheet (note that the system's default font will be gathered during startup, so if its value changes at run-time you will have to restart QMC2 for correct behavior)
imp: reduced (eliminated?) flickering upon creation of game-/machine-specific emulator configuration widgets
imp: the game/machine search function now also searches through the 'short names' (or game/machine IDs), so for instance entering 'snes' would also return valid results for MESS
imp: variant launching now also works on Windows (it's assumed that the 'other' variant exe can be found in the same path as the currently running one)
imp: MESS targets: device configurator: modified the extension filter to be case-insensitive when browsing for device files, added a 'clear' button to reset a device instance mapping and added a 'remove configuration' action to the context-menu for available device configurations
imp: ROMAlyzer: honor the system locale when logging CHD header information (logical size and other numbers)
new: added command line option -qmc2_config_path to allow for overwriting the path where QMC2 stores its setup, caches etc. -- it's in the user's responsibility to copy/move the data to the desired directory (otherwise QMC2 will start over, which may be wanted behavior, though)
new: support for game/machine attached YouTube videos (Phonon-based video player)
new: added 4 new tool-functions to allow for forced removal of any game-/machine- and software-list related cache data stored on disk
new: added support to provide lists of available BIOS sets (MAME & MESS) and RAM size options (MESS-only) in the game/machine-specific emulator configuration widgets
new: MESS targets: added a 'general software folder' setting used as the default directory for the MESS device configurator (when no individual software folder was specified explicitly); when a sub-folder named as the currently selected machine exists in this directory, that folder will be selected automatically
new: MESS targets: enabled the use of a 'cabinet detail' for MESS as well
new: added support for the MinGW (GCC) compiler on Windows (you need the MAME dev-tools plus the QMC2 add-on package for your architecture)
wip: completing the support for software lists -- basically working, but some planned functionality is still missing, and there are open questions regarding the official way to scan the hash XML data
doc: added Q2.14, Q2.15, Q2.16 and Q2.17 to the FAQ

v0.2.b19, 03-APR-2011:

fix: ROMAlyzer: corrected status determination for ROM files that have no dump (but for which the file size or any checksums are available through the XML data)
fix: corrected the scrolling behavior of the front-end and emulator logs
fix: MESS targets only: corrected ROM status determination for machines that require no ROMs
fix: correctly display document titles / title changes in the mini web browser
fix: MP3 player: corrected auto-repeating of pressed (and held) fast-forward / fast-backward buttons
fix: corrected MAWS web-cache compression (works also on Windows now)
fix: embedder: avoid left-over embed container widget when an emulator dies unexpectedly while it's currently being embedded
fix: demo mode: avoid saving game configurations while in demo mode (may crash)
fix: corrected the conversion to/from some (HTML encoded) special characters as used in a few game/machine descriptions and manufacturer names
fix: ensure correct parsing of XML attributes when retrieving game/machine details
fix: mini web browser: don't produce lower case URL patterns when validating entered strings
fix: corrected ROM cache updates on individual ROM status checks
imp: ROMAlyzer: improved performance for CRC identification of ZIP-archived ROM files
imp: ROMAlyzer: generally improved progress indication
imp: all logs are now based on read-only QPlainTextEdit's as this class is much better optimized for large amounts of plain-text data (compared to rich-text capabable QTextBrowser's, which were used before)
imp: SDLMESS/MESS templates updated to 0.141 (new option uifont, changed default value of writeconfig)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.142 (new option ramsize for all, new options syncrefresh, bench and watchdog for SDLMAME, removed option uimodekey for SDLMAME)
imp: MESS targets only: for machines that require no ROMs, the ROMAlyzer will now display both their emulation- and file-states as 'good' (as opposed to 'unknown' / 'not found' which was used before)
imp: launching of BIOS sets will no longer be prevented (it actually makes sense for some of them) -- except in demo mode, where BIOS sets are never selected
imp: Windows build: revised the VC++ project generation script to be fully automatic and to also support VC++ 2010 (requires sed for Windows now!)
imp: support for additional XML data in game/machine details (tag and mask as sub-elements of configuration)
imp: embedder: when embedder maximization is turned on, the menu-, status- and tool-bars as well as the game-/machine-list status frame are now automatically hidden while an emulator is shown
imp: embedder: the embedder maximization toggle button now uses two icons to indicate the action taken when it's clicked
imp: updated redistributed Qt translations from Qt 4.7.2
new: ROMAlyzer: added a checksum wizard to search for SHA1 or CRC hashes in all sets, to qualify the states of the results and to repair bad sets from good ones (note: the set repair function works only for ZIPs at the moment -- create backups before using it!)
new: ROMAlyzer: if a ROM or CHD file that's expected to be merged from a parent set is loaded from the child set instead, a warning is logged (may be obsolete); the report will contain green (OK), yellow (warning) or red (critical) symbols to indicate the merge status
new: ROMAlyzer: added a set rewriter function to programmatically rewrite (clean) ROM sets on demand and/or while analysing them (works only for ZIPs!)
new: ROMAlyzer: the number of reported sets held in memory can now be limited (which is important for long batch runs where the memory consumption can otherwise grow enormously); the new default behavior now is that after 1000 analyzed sets the ROMAlyzer will start to remove the oldest reports
new: you can now select the position chosen by QMC2 when scrolling to the current game/machine item (the setting actually applies to all views & lists); the default is top (= old behavior)
new: all game/machine detail images now have a context menu with a 'copy to clipboard' item
new: added new compile-time setting BROWSER_PREFETCH_DNS to allow for prefetching of DNS lookups by the mini web browser (Qt 4.6 and higher)
new: embedder: embedded emulators can now automatically be paused when they are hidden and resumed when they are shown (requires the MAME/MESS notifier FIFO in order to correctly track any state changes)
new: embedder: the current status of an embedded emulator is now indicated through traffic lights in the respective tab widget header
new: added support for a 'number of players' column to the game/machine list as suggested by Francisco Javier Felix (csfax) -- see bug tracker ID #14
new: ROMAlyzer: added a 'copy to clipboard' function to copy the analysis output for the currently selected set to the system clipboard (as formatted text)
wip: completing the support for game/machine attached youtube.com videos -- note: this is a Qt 4.7+ only feature as it uses the embeddable youtube.com video player which in turn needs the npviewer browser plugin (and that's only cleanly supported since Qt 4.7)
doc: updated Q1.7.2 in FAQ to reflect openSUSE 11.4
inf: SDLMAME & SDLMESS targets only: the output notifier FIFO (/tmp/sdlmame_out) is no longer removed when QMC2 exits to allow for clean concurrent use by multiple variants (that's actually a work around because SDLMAME & SDLMESS both use the same FIFO, and there's apparently no portable way to find out if it's opened by another process to decide when it's eligible for removal)

v0.2.b18, 02-JAN-2011:

fix: welcome dialog: the initial/optional hashpath setting must be stored under MESS (not MAME)
fix: Qt 4.7+ only: worked around a Qt bug that caused the first embedded emulator whose options were activated to disappear (visually)
fix: corrected concurrent/mixed joystick control when emulators are embedded
fix: avoid a QWebInspector warning by setting the application's organization name (only for builds with BROWSER_EXTRAS=1); as a result, QWebInspector will now correctly (re)store its settings in ~/.config/qmc2.conf
fix: corrected cursor positioning when editing strings in delegated item views (emulator configuration widgets and MESS device setup)
fix: avoid possible qUncompress() warnings due to empty input data
fix: embedder: corrected client resizing issues on maximized embedded emulators
fix: embedder: make sure the next visible embedded emulator (if any) gains input focus when the currently focused embed client is released
fix: set the codec for C-string conversion to the current locale's codec in order to correctly support unicode characters used in XML data (however, note that this makes the creation of XML- and gamelist-caches a bit slower)
fix: ROMAlyzer: just because chdman verifies the file integrity as good doesn't mean that it's the wanted file, so we still need to use the header checksums for comparison
imp: foreign emulator support: a working directory can now also be specified in the registration of foreign emulators (this was particularly added to support RAINE, but it's a good idea anyway)
imp: SDLMESS/MESS templates updated to 0.140 (no new or changed options)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.141 (new options profile and bench for MAME, new option uifont for all, changed default value of coin_lockout for MAMEUIFX32, removed option volume_adjust for MAMEUIFX32, new option hashpath for all)
imp: UNIX build: forcedly disable pretty compilation output ('make PRETTY=1 ...') for Qt 4.7+ as it produces irritating (but harmless) shell warnings
imp: updated redistributed Qt translations from Qt 4.7.1
imp: embedder snapshot tool: the snapshot viewer now also hides itself when the escape key is pressed -- we're no longer bypassing the X11 window manager and are instead using a managed frameless window (the window manager must understand Motif and/or NETWM hints for this to work; however, most - if not all - modern WMs should be able to handle this)
imp: embedder: cleaner layout handling to avoid flickering borders due to auto-maximization
imp: ROMAlyzer: checksum columns will only be shown in the analysis report when their calculation has been enabled in the settings
imp: support for additional XML data in game/machine details (status for ROMs, disks and software-lists, optional for ROMs and disks)
new: embedder: the embedder options drop down menu now also contains a copy command item
wip: adding support for game/machine attached youtube.com videos -- will likely only work for Qt 4.7+ as it uses the embeddable youtube.com video player which in turn needs the npviewer browser plugin

v0.2.b17, 22-OCT-2010:

fix: embedder snapshot tool: the first snapshot clicked wasn't displayed in the viewer
fix: demo mode and ROM checks aren't allowed to run at the same time (would crash); additional emulators shouldn't be launched while in demo mode -- both will be avoided now
fix: ROM check: on fast machines, the first few check results got lost sometimes (this was a serious bug!)
fix: the game/machine status indicator wasn't correctly updated when the ROM status of the currently selected game/machine changed during a ROM check
fix: consider the MAWS cache as invalid when the MAWS base URL is changed (cleared now)
fix: corrected widget layout restoration for image- and sample-check dialogs
fix: when the tool-executor dialog gets closed while the external program is still running, the process must be killed
fix: MESS targets only: don't try to load machine icons (we don't support them anyway in case of MESS)
fix: ROMAlyzer: corrected icon size adjustment
fix: ROM status toggles were effectively disabled when the applied configuration was restored by the user
fix: embedder: corrected initial focus and container maximization issues
fix: joystick test widget: if a style sheet is active, the button test labels must be colorized with a style sheet as well (instead of changing their palette)
fix: icon sizes of the MAWS quick download setup dialog are now also correctly adjusted
fix: ini-importer/exporter: when the inipath hasn't been set explicitly, try to use the template's default value instead
imp: SDLMESS/MESS templates updated to 0.139 (no new options, corrected default value for option writeconfig)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.140 (no new or changed options)
imp: Mac OS X build: determine correct SCM revision used for CFBundleVersion in Info.plist, call macdeployqt only when necessary, use correct permissions on directories for system-wide installation
imp: demo mode dialog: added a label to display the name of the currently played game
imp: about dialog: supported MIME types (Phonon backend) shown on the sys-info page are sorted now
imp: support for additional/new XML data when retrieving game/machine details (configuration, adjuster, category and softwarelist)
imp: updated the MAWS quick download links to the current site layout
imp: the tool executor dialog can now auto-close and copy the tool's output to the front end log (i.e. for debugging)
imp: additional empty-line consolidation for game/machine info texts
imp: the demo mode dialog now (re)stores its geometry
imp: build: cleaned up the build system in many aspects, added several new make options (for special build environments)
imp: keep an internal run-time index of the XML data when searching and retrieving game/machine details (making subsequent retrievals of the same data slightly faster)
imp: embedder: using the internal emulator ID to set the WM_CLASS property in order to make the emulator's X11 window uniquely identifiable (this means that multiple windows with the same emulated game/machine can now be cleanly embedded!)
imp: the hierarchical parent/clone view is now also hidden during game/machine list reloads (if applicable)
imp: embedded emulator windows are now automatically maximized to use all available space within their parent widgets (no margins)
imp: file & directory editors in the emulator configuration widgets use tool-buttons (instead of push-buttons) now for better consistency
imp: textual descriptions for emulator exit codes
imp: using separate semaphores for the serialization of log data (front end and emulator logs)
new: added generic support to drive a ROM tool for any external processing based on the game/machine ID ($ID$) or description ($DESCRIPTION$)
new: URLs in the game/machine and emulator info DBs are now directly clickable (opening the URL in the desktop's default browser, if any)
new: MESS targets only: MESS wiki texts from sysinfo.dat are now converted to HTML (far from perfect, but basically working fine)
new: experimental support for Qt 4.7 -- browser plugins appear to work nicely using Qt 4.7, so you could enable the compile-time option BROWSER_PLUGINS in this case; however, there's at least one embedder-related issue left: toggling the embedder options will lead to a black screen for the embedded emulator's window, but only the first time it is used (strange)
wip: MESS targets only: completing the support for MESS software lists -- basically working, but some functionality is still missing
wip: started to add support for an optional ROM/CHD database, a repository to store and retrieve unique copies of ROM and CHD data
wip: added the current template-tool wip to the SVN trunk
doc: updated Q1.7.1 and Q1.7.2 in FAQ to reflect Ubuntu 10.04, Ubuntu 10.10 and openSUSE 11.3
doc: updated the ROM status table in section 4 of the README to better describe the meaning of the different states
inf: Greek translation dropped

v0.2.b16, 30-JUL-2010:

fix: correctly clear the MESS device configurator when the machine list is reloaded
fix: MP3 player (cosmetic): forcedly stop the progress bar's unknown length animation when a stream (or track) is stopped
fix: Mac OS X build: removed i386 and ppc requirements from the qmake/xcodebuild configuration
fix: Mac OS X build: corrected build rules for the mixed Qt/Cocoa environment
fix: if a font hasn't been set yet, use the QApplication's current font to initially feed the font dialog (on Mac OS X, 'Arial' and 'Courier New' are used as the initial fonts for that dialog)
fix: removed the deprecated Encoding key in the desktop entry template (see http://standards.freedesktop.org/desktop-entry-spec/latest/apc.html)
fix: ini-importer: correctly handle quotation marks and white space in string values
fix: Qt bug circumvention on Mac OS X: combo box and button pop-ups were strangley displaced in some parentless dialogs
fix: corrected the welcome dialog's UI (logo pixmap wasn't displayed)
fix: MP3 player: corrected multi-track selection behavior when in playback mode
fix: tweaked full sreen startup for Qt 4.6+ to ensure that the main window is raised
fix: restore Qt's default message handler shortly before exiting (this may fix crashes caused by Qt warnings posted after the QApplication object has been destroyed)
imp: SDLMESS/MESS templates updated to 0.138 (new option newui for MESS only, ignored in all SDLMESS builds)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.139 (new option writeconfig)
imp: added / changed a number of icons in the classic image set
imp: updated template format to v0.2.3 which adds support for OS-specific default attributes and the ability to ignore certain options on specific OSs (namely Mac OS X)
imp: besides better text, the welcome dialog now also includes an optional entry to specify the hash path (in case of MESS, which needs it to support software lists cleanly)
imp: the MESS device configurator now also determines the devices' brief names (to make it compatible with MESS software lists)
imp: build: added make options BROWSER_JAVA and BROWSER_JAVASCRIPT to allow for a compile-time decision to enable Java and/or JavaScript (default: both enabled, current behavior)
imp: about dialog: added output of the Qt build key and MIME types supported by the Phonon backend to sys-info page
imp: MP3 player: display the buffer fill level (percentage) while in buffering state
new: MP3 player: when Qt 4.6+ is used, the volume slider is replaced with a nice new volume dial
new: MP3 player: support for available audio effects (depends on Phonon backend capabilities) -- CAUTION: certain effects may cause crashes!
new: you can now specify the working directory that's used when the emulator is executed in play or demo mode (optional, but recommended)
new: MP3 player: the playlist now supports drag & drop to move items internally
wip: MESS targets only: support for MESS's new -listsoftware feature (new since version 0.138) as a new machine detail -- not really working yet, but basic GUI integration and software list caching are done -- thanks to etabeta78 for the suggestion
doc: added Q1.7.4 to FAQ

v0.2.b15, 16-MAY-2010:

fix: correctly change the view menu's and game list tab's icons when the view is selected via the combo box under the game/machine list
fix: ROMAlyzer (cosmetic): forcedly update the result tree widget after each individual analysis (circumvents rare update issues when the ROMAlyzer isn't the active window)
fix: correctly honor the escape key in the global emulator options when its temporary search widget is hidden (i.e. cancel/close the setup dialog instead of eating the key press)
imp: SDLMESS/MESS templates updated to 0.137 (new/changed options debug_internal, natural and uimodekey)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.138 (no new or changed options)
new: added boolean option PlayOnSublistActivation to interprete item activations in search-, favorites- and played-lists as start playing commands instead of jumping to the game/machine list (default: false, current behavior)
new: added a new ROM types column to all game/machine lists and the ROM status exporter (the game/machine list cache will be updated automatically)
new: the exit/stop action now blinks when there's background activity, giving better indication of the activity itself as well as the action's second function (stop all current activity)
new: MAME targets only: added optional support for catver.ini from http://www.progettoemma.net/?catlist; this includes standard game list integration as well as two new views (view by game category / view by emulator version the game was added)
new: MP3 player: also handles MP3 streams now (simply add a valid URL instead of a file name)

v0.2.b14, 12-MAR-2010:

fix: MAME/MAMEUIFX32 templates: corrected default value for audio_latency, added new option numprocessors
fix: build: disabling joystick support caused compilation errors -- thanks to Marcelo Bossoni for reporting the issue
fix: corrected a set of initial setup issues (when there's no valid user-scope configuration for the respective QMC2 variant)
fix: corrected template checking for default values containing white-space (bug tracker ID #11)
fix: after checking icons, widget updates to the detailed game/machine list were disabled -- thanks to Robert Hamberger for reporting the issue
fix: the game/machine list header's sort indicator wasn't correctly shown when the load process finished
fix: corrected the MP3 player's internal state handling
fix: avoid crashes when switching style sheets on-the-fly
fix: avoid auto-scrolling of any game-/machine-list when returning from an embedded emulator
fix: prevent the menu-bar's context menu from being displayed (it may irritate the user that settings made through it aren't (re)stored)
fix: corrected full screen restoration on startup for desktops with multiple screens
imp: the search pattern combo box is now part of the search tab widget (which appears more intuitive and leaves vertical space for better uses)
imp: delaying initial main widget updates until all basic initializations & GUI reconstructions are finished
imp: added distribution-specific package specs to the source tree (see directory pkg-specs/)
imp: delaying automatically triggered ROM checks for 250ms (in the hope it avoids rare crashes on slower systems)
imp: nice performance improvements for ROM state filtering and loading of cached data (ROM state cache, game/machine list cache and XML cache)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.137 (new options debug_internal, natural and uimodekey)
imp: SDLMESS/MESS templates updated to 0.136 (new option numprocessors)
imp: embedder snapshot tool: positioning the snapshot viewer more intelligently, scaling the snapshot preview down to 50% of the captured size (if its size is larger than the native resolution)
imp: build: QTDIR is no longer used -- use QMAKE instead, which defaults to qmake (that is, the qmake command found in $PATH)
imp: added new alternative image sets circles and cubes (95% the same as the classic image set, except the colored spheres are replaced with styled circles / cubes)
imp: embedder: show a message box and let the user decide if to retry an embedding operation if a window ID couldn't be found but the corresponding emulator was active at that time
imp: honoring desktop/screen geometry limits when positioning context menus
imp: setting the update delay to 'none' (0) will now cause synchronous updates when the game/machine selection changes; values higher than 0 will cause asynchronous updates just as before
imp: embedder snapshot tool: by default, take snapshots in the game's/machine's native resolution
imp: build: added the new make option L_FLAGS to pass additional flags to the linker
new: embedder: added a toggle switch for automatic horizontal maximization of embedded emulator windows
new: ROMAlyzer: CHD manager integration for optional deep verification (+ fixing) and automatic updates of CHDs -- caution: create backups before enabling the CHD manager!
new: the main widget's splitters now have their own context menus to allow for orientation flipping and swapping of their sub-widgets/sub-layouts -- this allows a free (to a certain extent) layout of all major widgets!
new: embedder: the embedder options toggle button now also includes a drop down menu (opened after a short delay when the button is held down) to terminate/kill the emulator or to add the game/machine to the favorites list (more actions may follow perhaps)
new: MAME targets only: added a demo mode which runs random games from the overall list (filtered by ROM state) for a selectable period of time -- this has been requested by some MAME cabinet users for whom it may be useful
doc: added Q3.6 and Q2.13 to FAQ

v0.2.b13, 02-JAN-2010:

fix: minor: use reverse order when loading translators (first load the Qt translations, then QMC2's translations -- Qt searches the loaded translations in reverse order, that is QMC2's translation will now be used with higher precedence)
fix: disable MAWS cache directory browse button during reload
fix: worked around a Qt bug that inhibits font changes through QApplication::setFont() when a style sheet is active
fix: restored forced backround widget updates for Qt versions >= 4.5.3 (MAWS quick links feature), delaying it to allow Qt to process all pending events (not perfect: may flicker)
fix: hide the MAWS quick links button when its menu is (auto-)hidden and the mouse cursor has left the browser widget in the meantime
fix: corrected minor focus issues after game/machine list reload
fix: MAWS lookup: don't try to download the startup URL when we're offline
fix: audio player: initially scroll playlist to the track last played (if any)
fix: using update() wherever repaint() was used to redraw game/machine images (among other things, this corrects some long-standing minor item selection issues)
imp: build: added a build configuration file for NetBSD (see arch/NetBSD.cfg) -- thanks to Jürgen Buchmüller for testing QMC2 in this environment and reporting his results
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.136 (SDLMAME only: new option numprocessors)
imp: SDLMESS/MESS templates updated to 0.135 (no new or changed options)
imp: added/replaced a number of embedded icons to/in the classic image set
imp: improved the error handling of the process manager
imp: build: added new make options CC_FLAGS and CXX_FLAGS to pass additional flags to the C/C++ compiler
imp: reparent the detail setup dialog to the widget it was called from (main widget or settings dialog)
imp: removed programmatic scrolling of front-end and emulator logs on new entries (using Qt's default now, which allows the user to scroll back and uses automatic scrolling when at the end of the log)
imp: improved synchronization of log browser updates
imp: minor: forcing PNG format when loading images, which offers a small performance increase
imp: during a session, the item expansion state and scroll bar values of game-/machine-specific emulator configurators are preserved
imp: using QStyledItemDelegate as base-class for item delegation (Qt recommendation)
imp: tool tips with descriptions are now also shown for the names of emulator options (not only when hovering their editors/values)
new: support for additional (foreign) emulators which can be used on a per-game/-machine basis
new: Portuguese translation by Marcelo Bossoni
new: experimental support for Qt 4.6 (note that Qt 4.5 is still the required and recommended version)
new: added new make option BROWSER_PLUGINS to enable/disable the use of browser plugins (default: disabled)
new: X11 only: added support for optional/on-demand embedding of emulator windows through the XEmbed extension (note that without minor modifications to SDLMAME/SDLMESS, there's currently no way to distinguish between multiple instances of the same emulator, running the same game/machine) -- requires xwininfo!
new: X11 only: optional embedder functions (snapshot tool, additional features planned)
new: added new make option XWININFO to supply an alternate path to xwininfo (default: "xwininfo")
new: added ability to specify a separate (i.e. fixed sized) font for all log browsers
new: except for menus, all static icons are now scaled/adjusted to the size of the current application font (even icons on the tool bar)
new: emulator configurator widgets now use check boxes (instead of combo boxes) for all boolean settings
doc: updated Q1.7.1 and Q1.7.2 in FAQ to reflect Ubuntu 9.10 and openSUSE 11.2

v0.2.b12, 01-NOV-2009:

imp: minor main widget layout improvements (MP3 player)
imp: updated redistributed Qt translations to Qt 4.5.3 and integrated them into build system
imp: new (transparent) QMC2 logo
imp: log loading of style sheets only if the name changed (this effectively suppresses the second log entry during initialization)
new: added optional live indicator for physical memory utilization to main widget
new: variant launcher: support for spawn & quit when launching another variant (optional, mainly for low memory systems)
new: template check against the running emulator's options and defaults
doc: added Q1.11 and Q2.12 to FAQ

v0.2.b11, 10-SEP-2009:

fix: corrected default short cuts for audio player functions jump to previous/next track (old short cuts were already used by X.Org X11 servers, now using Ctrl+Alt+Left/Right)
fix: custom palettes and style sheets are mutually exclusive (this fixes minor palette issues with the menu- and tool-bars when switching styles / style sheets on-the-fly)
fix: options dialog: adjusted some texts & tool tips for MESS targets
fix: corrected MOC warning for arcade/arcadeitem.h related to a missing Q_INTERFACES() statement when using Qt 4.6+
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.134 (no new options)

new: options dialog: provide a push button to open the detail setup dialog from the main GUI settings
doc: updated Q1.7.1 and Q1.7.3 in FAQ to reflect Ubuntu 9.04 and Fedora 11

v0.2.b10, 20-JUL-2009:

fix: clear MAWS lookup correctly when reloading game list
fix: corrected icon size adjustment for mini web browser, detail setup and ROM status exporter
fix: fixed a series of race conditions with activated Qt style sheets (Qt 4.5.2+ is recommended when using style sheets)
fix: audio player: when starting to play a new track, scroll playlist to the file currently played
fix: disable a number of widgets to avoid launching of modal dialogs when the emulator and/or game/machine info DBs are loaded (would interrupt the load progress)
imp: log discovered emulator type (MAME or MESS) together with its version
imp: download manager: remember / preselect last storage path when presenting the file name chooser, show download details in tool tip
imp: about dialog: using QDesktopServices to launch default browser when following links
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.133 (new option burnin, crsshairpath changed to crosshairpath)

imp: updated redistributed Qt translations to Qt 4.5.2
imp: greatly improved download retry logic & timing
imp: build: added new distribution specific build configuration for Debian Squeeze (thanks to Tomasz Moń)
imp: cosmetic: added detection of Windows 7 and Mac OS X 10.6 to about dialog
imp: code cleanup: set and (where possible) use QMC2_EMUTYPE_MAME/QMC2_EMUTYPE_MESS macros instead of OR'ed emulator target macros to select MAME-/MESS-only code segments
new: built-in support for dynamic loading of Qt style sheets -- note: due to a Qt bug, for now we have to change the current working directory to the style sheet's directory to make sure relative paths (image URLs) are handled correctly
new: support for PCB images as an additional game/machine detail
new: added new make option FADER_SPEED to select the speed of audio fading at build time (0: fastest/instantly, >0: slower, default: 100)
new: MAWS quick download links (manual and automatic) -- supports all available in-game previews, title snapshots, icons and cabinet art images (flyers, cabinets, control panels, marquees and PCBs)
wip: Greek translation (thanks to Giorgos Kostopoulos)
doc: adopted new homepage look to all docs

v0.2.b9, 08-JUN-2009:

imp: build: Windows: add icon to binary target exe (qmc2-emulator.exe)
new: all UI files regenerated with Qt 4.5's designer -- Qt 4.5.0+ promoted as the new required version -- Qt 4.4 is no longer supported!

new: using the new mini web browser to display online documentation (includes support for external links)
new: save/restore layout of documentation browser (not its visibility), made it an independent widget
new: download manager for use with web content, integrated into the main widget (still needs a bunch of improvements, but basically does its job -- also, there are still some QtWebKit issues we've tried to work around as far as possible...)
doc: changed all occurrances of external URLs to real href's (only http://... URLs supported)

v0.2.b8, 23-APR-2009:

fix: completely removed buggy settings conversion code
fix: ensure trailing slash for data-directory for path returned by standard dialog
fix: corrected variant launch on Mac OS X -- now uses LaunchServices to locate the other variant
fix: full ROM check: increase progress indicator during final determination of games/machines with a not found ROM status (or when the ROM states of all remaining systems need to become unknown due to interruption)
fix: use rompath and samplepath only if they have been explicitly set, otherwise fall back to the default paths (roms, samples)
fix: start emulator audit processes after their signals were connected (otherwise we can't be sure on all platforms that the QProcess::started() signal will be catched)
fix: insert process map entry before starting the emulation (same reason as preceding fix)
fix: ROM state toggles weren't correctly initialized at very first start
fix: corrected position restauration of image checker dialog

fix: fixed crashes when the game- or emulator-info widgets were visible during game-/machine-list reload
fix: correctly update the ROM state toggles when the ROM state filter is changed through the options dialog
imp: revised executable check of emulator binary to work platform independently
imp: SDLMAME template updated to 0.131 (new option crsshairpath)
imp: SDLMESS template updated to 0.130 (no new or changed options)
imp: completely reverted the use of wildcards (*) on full audit calls -- makes more troubles than it brings benefits
imp: ROMAlyzer: skip unsupported CHD formats
imp: pressing Qt::Key_Escape in the emulator configuration does no longer open the alphanumeric search widget, but will close it if it's currently visible
imp: updated template format to include the two new option types directory and file (new format version 0.2.2)
imp: code cleanup: replaced all occurrences of getenv("HOME") with QDir::homePath() as it is more platform independent
imp: print warnings to the front end log if emulator audit calls don't exit cleanly
imp: ROM check: set ROM status of remaining games/machines to unknown if the emulator crashes while auditing
imp: updated redistributed Qt translations to Qt 4.5.0
imp: main widget improved to allow for even more layout flexibility
imp: ROMAlyzer: changed some default settings to be more like "what the user expects"
imp: earlier initial style setup, also circumvents a minor issue with the GTK+ style
imp: worked around an annoying Qt bug that sometimes left the menu- and tool-bars at the wrong style or color palette (when changing the style dynamically)
imp: removed icon-related GUI representations for MESS targets (there are no usefull MESS machine icons we're aware of)
new: Mac and Windows only: show version of running OS on the sys-info page of the about dialog
new: show Phonon runtime version on the sys-info page of the about dialog (if applicable)
new: support for Windows^TM and the original versions of MAME & MESS (including some of their variants)

new: added new template for the original version of MESS on Windows (see data/opt/MESS/template.xml, initial version 0.130)
new: added new template for MAMEUIFX32 on Windows (see data/opt/MAMEUIFX32/template.xml, initial version 0.131) -- use this template together with the MAME variant on Windows to cleanly support MAMEUIFX32 through QMC2
new: added batch script for VC++ project file generation on Windows (see scripts/generate-vcprojects.bat -- preliminary, you'll have to adjust the path variables if you're going to use this script!)
new: added new game/machine list setting called DoubleClickActivation to let the user enable/disable the start of an emulator on mouse double-clicks (may be annoying)
new: build: added new VARIANT_LAUNCHER make option to enable/disable the QMC2 variant launcher at compile time (default: enabled on UNIX and Mac, disabled on Windows for now)

doc: revised many paragraphs to better reflect platform-specific and common information

v0.2.b7, 09-MAR-2009:

fix: ini-import/-export didn't work correctly when built for SDLMESS
fix: clear search results list when search pattern is empty
fix: ROMAlyzer: correctly reset the progress bar after analysing a game/machine for which the XML data indicates that it has no ROM files (MESS example: genesis)
fix: corrected item cursor behavior in parent/clone hierarchy view on rapidly changing selections (i.e. when hovering over the list)
fix: loading translations earlier now to allow for a translated welcome wizard
fix: SDLMESS variant: store machine-specific emulator configurations in the [MESS] section
fix: corrected a minor initial item selection issue for search results, play history and favorites lists
fix: ensure a trailing slash for preview-, flyer- and icon-directories for paths returned by the directory selection dialog
fix: corrected a series of bugs related to trimming the cached XML data -- if you don't update MAME/MESS when first using this (hopefully) fixed version of QMC2, it's recommended that you remove the gamelist- and XML-caches prior to starting QMC2 (the caches will be recreated cleanly)
fix: ROMAlyzer: use full range of main progress bar
fix: ROM state filter: correctly reset the progress bar after the filter has been applied
fix: corrected a minor style setup issue on startup

fix: center main widget on desktop if its restore position is yet undefined
imp: build: added installation of desktop entry files
imp: build: added optional support to build against a local / alternate SDL library (see new make options starting with SDLLOCAL) - the default is to use whatever SDL library the system may default to

imp: SDLMESS configuration template updated to 0.129 (revised several option descriptions, removed remapjoys and remapjoyfile, added new options joy_idx1 - joy_idx8)
imp: ROM status exporter: more SDLMESS specific updates to translatable texts
imp: build: add qmc2.pro dependency for Makefile.qmake target
imp: avoid potential locking during the determination of the emulator's version & supported games/machines due to a probably failed reception of the sub-process' finished() signal

imp: ROMAlyzer: show count down in analyzer status
imp: code cleanup: replaced all occurrances of obsoleted QWidget method setShown() with setVisible()

imp: more flexibility to layout the main widget (note that this can lead to unusable sub-widgets if you overdo what's possible :)
imp: ROMAlyzer: colorize wrong checksums in red, unknown states in blue
imp: build: added new ARCADE_OPENGL make option - if enabled (default), QMC2's arcade mode will support OpenGL (if available - direct rendering/hardware acceleration recommended!), otherwise only the software renderer will be available (should be fast enough, though)
imp: build: added new WIP make option - if set to 1, unfinished code will be made available (default = 0/disabled)
imp: updated redistributed Qt translations to Qt 4.4.3
imp: build: added new QT_TRANSLATION make option - set this to the absolute path to your Qt translation files if you don't want to use the ones which are redistributed with QMC2 (which is the default)
imp: welcome wizard: remove initial sample path setup for MESS variant because MESS doesn't support samples anyway
imp: added distribution specific build configuration for Mandriva Linux release 2009.0
imp: use -listfull '*' / -listxml '*' (instead of just -listfull / -listxml) to determine the total number of supported games/machines and their detailed XML data - some MAME/MESS builds wouldn't report the full game/machine list without the asterisk
imp: ROMAlyzer: log elapsed time after analysis
imp: improved full screen toggling of main widget -- should work generally better now and be more independent of the window manager
imp: build: out-of-the-box build support for Mac OS X (Darwin) -- thanks to Vas Crabb!
new: log activation of joystick support and the run-time version of SDL (if applicable)
new: show compile- and run-time versions of SDL in about dialog (if applicable)
new: log run-time version of Phonon (if applicable)
new: added new setting ParentImageFallback (default: false) to enable falling back to the parent's image if an individual clone's image doesn't exist (but the parent's image does)

new: added new setting CheckSingleInstance (default: true) to enable/disable a startup check against multi-instance runs of the same QMC2 variant
new: all QMC2 variants are now separately configured - includes automatic settings conversion (if required) and automatic cloning of a probably already existing front end configuration (from another variant)
new: added runonce utility to project for use with the QMC2 variant launcher
new: QMC2 variant launcher: both QMC2 variants (qmc2-sdlmame & qmc2-sdlmess) can launch one another; if the other variant already runs, try raising it - note that this feature is very dependent on the window manager which may decide to ignore XMapRaised(); on KDE for example, it will only work correctly when focus under mouse or focus strictly under mouse has been set!)
wip: arcade mode (not working in this release -- disabled by default -- use "make WIP=1 ..." for a preview)
doc: added Q2.11 to FAQ
inf: checked SDL 1.3 (experimental!) compatibility of joystick API
inf: trying to build with Qt versions less than 4.4.0 is now completely inhibited!
inf: long project name changed to M.A.M.E./M.E.S.S. Catalog / Launcher II
inf: build: compile time measurement is disabled per default now
inf: there's nothing like an emulator info DB for MESS, so this feature is completely disabled in case of QMC2 for SDLMESS
inf: project home page moved to http://qmc2.arcadehits.net -- thanks to Vincent Bousquet
inf: checked Qt 4.5+ compatibility (recommended due to much better performance!)

v0.2.b6, 05-JAN-2009:

fix: startup crash on the creation of the template configuration map under certain circumstances (see tracker #2201714)
fix: worked around a minor Phonon issue with duplicate metaDataChanged() signals
imp: SDLMAME options template updated to 0.129 (corrected default value for audio_latency, revised several option descriptions, removed remapjoys and remapjoyfile, added new options joy_idx1 - joy_idx8)
imp: updated template format to include the template's emulator name (new format version 0.2.1)
imp: ROMAlyzer: determine ROM file CRC identification troubles in ZIPs, log warnings and set the file status to bad in such a case (in contrast to not found as before)
imp: code cleanup: changed several macro definitions to be consistent within QMC2's namespace
imp: build: added new make options DISTCC, DISTCC_CC & DISTCC_CXX (uses a distributed compiler such as distcc or icecc if DISTCC is set to 1 - check/set DISTCC_CC / DISTCC_CXX if enabled!)
imp: slightly improved welcome dialog (logo, button icons and layout)
imp: build: preserve existing system-wide configuration (usually /etc/qmc2/qmc2.ini) on make install
imp: build: avoid overwriting the Makefile when qmake is accidently called standalone (the project file now sets QMAKE_MAKEFILE to Makefile.qmake)
imp: build: allow pretty compile output (doesn't work for RCC yet due to a qmake bug) - enabled per default, use make PRETTY=0 to disable
imp: build: splitted CCACHECMD into CCACHE_CC & CCACHE_CXX
imp: build: use the same qmc2.pro project file for both debug and release builds (adding CONFIG settings dynamically on qmake call)
imp: ROMAlyzer: log more CHD v3 header information (CHD tag, writable flag and parent's MD5/SHA1 checksums, if applicable)
imp: ROMAlyzer: if romof is set in a game's XML data, but the file to merge is missing from this data (= merge attribute is empty), recursively search for the name of the current game's ROM file instead - MAME does exactly this in these rare cases (example: sfiiin)
imp: ROMAlyzer: produce better status and log information on CHDs that were not found
imp: allow higher values for gamelist responsiveness - setting this value higher than the total number of games will usually allow for less than 2 seconds of gamelist processing (at the expense of a more or less unresponsive GUI during reload, of course)
imp: updated XML game info parser to support all current game/machine settings from MAME/MESS
imp: many [Frontend] settings moved to [MAME] and [MESS] sections (automatically converted if the previous version is less than 0.2.b6)
imp: code cleanup: make class and variable names emulator independent (i.e. use EmulatorOptions instead of MameOptions)
new: added new SDLMESS options template (see data/opt/SDLMESS/template.xml, initial version 0.128)
new: experimental support for SDLMESS (status: very basic and no device support yet)
new: added plugin helper sample script for emulator startup interception (see scripts/plugin_helper.sh)
new: all UI files regenerated with Qt 4.4's designer - Qt 4.4.0+ promoted as the new required version, although you may still be able to build it using Qt 4.3 in the short term - Qt 4.3 is no longer supported!
new: added tab icons for all main widget functions
new: ROM status export tool with support for ASCII, CSV and HTML output formats - can output to file or clipboard
doc: added Q2.10 to FAQ
doc: added Ubuntu 8.10 (Intrepid) as an officially tested distribution to the FAQ (see Q1.7.1)
doc: added Fedora release 10 as an officially tested distribution to the FAQ (see Q1.7.3)
doc: added openSUSE 11.1 as an officially tested distribution to the FAQ (see Q1.7.2)

v0.2.b5, 16-OCT-2008:

fix: corrected a serious bug in ROM state and gamelist caching introduced by trimming the data - please remove all cache files from previous releases before using this version, otherwise QMC2 is likely to crash (rm ~/.qmc2/mame.lxc ~/.qmc2/qmc2.rsc ~/.qmc2/qmc2.glc)
fix: corrected the shortcut scope of several actions

imp: layout improvements for the ROMAlyzer (file I/O indicator now vertical)
imp: code cleanup: prepend QMC2_ to SDLMAME macro internally

imp: exchanged Qt logo due to Qt rebranding as of 4.4.3
new: support for MAME output notifications via a named pipe (SDLMAME 0.127+)
new: emulator control panel changed to a multi-column tree widget displaying more information like the game name, its LEDs (if applicable), the current emulator status and additional notifiers/values not handled statically (in a sub tree)
new: added a copy command menu item to the emulator control panel's context menu to allow for easier copying of emulator command lines to the system clipboard
new: individual joystick axes can now be enabled/disabled at will (this should make Sixaxis users happy :)
new: the number of lines kept in the ROMAlyzer log can now also be limited
new: optional support for background music playback (requires Qt 4.4+ / Phonon API - feature will be completely disabled for Qt 4.3)
new: the boolean emulator option values true and false are now also translatable
doc: added Q2.9 to FAQ

v0.2.b4, 19-AUG-2008:

fix: joystick mapping initially didn't work before the options were explicitly applied
fix: keep game-specific emulator configurations open only as long as they are really needed
fix: corrected support for keyboard shortcut mapping with multiple modifier keys
imp: try to use system locale to setup the language if no language was specified (or if the language is unavailable within the translations); fallback to us as last resort
imp: joystick test and calibration widgets are enclosed in scrollable areas now to allow for better handling of high amounts of axes or buttons; due to this, the layout management for these widgets was totally revised
imp: minor speed ups for loading of XML and gamelist caches by reading data block-wise
imp: SDLMAME options template updated to 0.127 (yuvmode replaced with scalemode, removed cheat_file, added new options cheatpath, videodriver, audiodriver and gl_lib)
imp: code cleanup: use constants instead of numbers for logical gamelist columns, prepend QMC2_ to JOYSTICK and OPENGL macros internally
imp: trimmed XML cache data - saves memory and disk space (plus adds a minor speed improvement upon cache reading)
imp: build: check required Qt version on call to qmake (see qmc2.pro*)
new: show number of (real/virtual) CPUs on system information page (about dialog)
new: the frontend and emulator log browsers can now be limited to the amount of lines they keep in memory (the default is unlimited as before)
doc: added Q2.8 and Q3.5 to FAQ

v0.2.b3, 07-JUL-2008:

fix: if a null pixmap was retrieved, display the ghost image instead (of nothing)
fix: under rare circumstances, the game specific emulator configuration wasn't updated correctly (empty widget)
fix: positions of about dialog and doc browser were incorrectly restored on showEvent()'s
fix: when switching between detailed gamelist and parent/clone hierarchy during reload, QMC2 crashed under certain circumstances (not absoluteley sure if this bug existed before or if it was introduced by new features of this release :)
fix: avoid auto-selecting first game in list if switching views during gamelist reload
fix: adjust icon sizes of shortcut redefinition buttons
fix: restore "Default" style selection correctly after language switch

imp: build: added support for distribution specific build on openSUSE 11.0, Fedora release 9 and Yellow Dog Linux 6.0
imp: build: moved os-detect.sh to scripts/ directory (where it belongs :)
imp: build: changed os-detection to be architecture independant for Linux distributions
new: optional use of OpenGL to draw images (previews & flyers) - decided at compile time with the new OPENGL make option (OPENGL=0 is the default and paints on a normal QWidget; using a QPainter on a QGLWidget is actually a bit slower)
new: optional direct GUI control via digital and analog joysticks (joystick support is enabled by default, use make option JOYSTICK=0 to completely disable it - note that compilation of QMC2 with enabled joystick support requires an SDL 1.2.11+ development package to be installed on your system!)
new: support for MAME's history.dat game information database
new: support for MAME's mameinfo.dat emulator information database
new: show memory information (total, free, used) in about dialog (see system info)
new: toggle fullscreen mode of main widget

new: game's short name (game ID) now also included in gamelist, plus added sorting by game name
inf: SDLMESS can only be used when compiled against the MAME target, of course :)

fix: don't try to analyze data if an incompatible executable was selected
fix: corrected several time measurements to be more precise
