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+

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

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: added new make option AUDIT_WILDCARD to enable/disable the use of wildcards ('*') on full audit calls if required (default: disabled)
new: free reordering & (de)activation of all available game/machine details

doc: changed all occurrances of external URLs to real href's (only http://... URLs supported)

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

fix: joystick calibration and test widgets: check current joystick index correctly (also fixes build issues with gcc 4.4)

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

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: 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)

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 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: code cleanup: use constants instead of numbers for logical emulator options columns

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 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)

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: the boolean emulator option values true and false are now also translatable
doc: added Q2.9 to FAQ

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: 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)

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 :)

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 mameinfo.dat emulator information database
new: show memory information (total, free, used) in about dialog (see system info)

new: added new setting ToolbarState to save/restore the toolbar position
new: added a built-in ROMAlyzer to deeply analyze a game's individual ROMs and CHDs

new: added remap function for shortcuts & GUI control keys
doc: todo: define missing features for 0.1 final, add planned features for 0.2 series
