+ * added some performance improvements when handling SDL surface scaling
+
+2014-09-04
+ * added custom graphics property "game.tile_size" to define in-game tile

+
+2014-09-01
+ * added custom graphics property ".tile_size" to define tile image size
+ for game element graphics (like "custom_1.tile_size"); non-standard

+
+2014-08-18

+
+2014-01-06
+ * fixed inconsistent custom artwork constants numbering in src/main.h,

+
+2013-12-16
+ * continued porting Rocks'n'Diamonds to Android (levels now playable)
+
+2013-12-12
+ * added SDL2 renderer/texture based graphics frame handling to allow for
+ "desktop" style fullscreen mode and scaling of game screen/window
+
+2013-12-11
+ * removed limitation of artwork files to selected file types (this means
+ that every file type supported by SDL_image and SDL_mixer can be used)
+ * changed default graphics from PCX to PNG (needed for Android version
+ to prevent painfully slow image loading, although not compressing PCX
+ files in the assets directory of the APK package might also work fine)

+ surface are the same (this bug also existed in versions of SDL 1.2.x)
+

+
+2013-11-13
+ * fixed problem with R'n'D restarting with same level set that may have
+ caused a problem (and therefore failing again and again); after an
+ error, the last level set is now deactivated in file "levelsetup.conf"
+ to restart with default level set (which should work without error)
+
+2013-11-07
+ * fixed determining main game data directory on Mac OS X "Mavericks"
+
+2013-11-04

+ when making use of the "time orb bug" (see element setting in editor)
+ (see level 053 of set "rnd_equinox_tetrachloride_ii" for an example)
+ * fixed graphics performance problems (especially on Mac OS X) by using
+ whole-playfield redraw on SDL target, while still using the previous
+ single-tile redraw method on X11 target (using redraw tiles threshold)
+
+2011-10-07
+ * fixed code (esp. random/tape handling) when compiled on 64-bit systems
+ (by replacing all "long" types by "int" types)
+
+2010-11-19
+ * fixed nasty bug (affecting crumbled graphics) after adding new special
+ graphics suffix ".TAPE" (and messing some things up in src/main.c)
+
+2010-08-04
+ * fixed wrong argument order in DrawTextBuffer() in gadgets.c
+ (this caused fonts in envelope config in level editor being invisible)
+
+2010-07-19
+ * fixed some problems with half tile size and even tile sized playfields
+
+2010-07-12
+ * added level selection screen (when clicking on main menu level number)
+ * added level tracing (played, solved) for use in level selection screen
+ (to display already played or solved levels in different font color)
+
+2010-06-24
+ * added alternative game mode for playing with half size playfield tiles
+ * fixed another memory violation bug in the native Supaplex game engine
+ (this potential memory bug was also in the original Megaplex code, but
+ apparently only occured under rare conditions triggered by using the
+ additional added preceding playfield memory area to make a few strange
+ levels using dirty off-playfield tricks (bugs) like "12s033.sp" also
+ solvable (this all worked fine in the classic DOS version, of course))
+
+2010-06-23
+ * added graphics performance optimization to native Supaplex game engine
+ * fixed bug with accidentally removing preceding buffer in SP engine
+ * moved some editor graphics from "RocksDoor.pcx" to "RocksMore.pcx"
+ (to prevent compatibility mapping of these newer graphics to older
+ (custom) versions of "RocksDoor.pcx" which did not contain them yet)
+
