+ * version 3.3.1.0 released
+
+2013-10-21
+ * version number set to 3.3.1.0
+
+2012-10-13
+ * fixed display of level time switching from ascending to descending
+ 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)
+
+2010-06-18
+ * added separately configurable game panel background to graphics config
+ * fixed displaying Supaplex time (now based on 35 fps instead of 50 fps)
+
+2010-06-16
+ * added tape panel graphics and screen positions to graphics config
+
+2010-06-15
+ * added compatibility stuff for redefined "global.door" (which affects
+ all parts of that image that have their own graphics definition now)
+
2010-06-14
* added sound button graphics to graphics config
