+================================================
+Release 11: 9 August 2022
 
 New/changed features:
+
 - When restarting a game with sound (MEGA65 only) Ozmoo detects that the sounds have already been loaded, making restart a lot faster.
 - Fixed PRINTSPEED mode which was broken. It now prints the # of instructions executed per second, twice per second.
 - Player can now switch to darkmode by pressing F1 on the splash screen.

 - Ozmoo used to ignore REU:s smaller than 512 KB. It can now use any REU size. The REU can be used to cache game data and/or scrollback buffer.
 
 Optimizations:
+
 - Faster way to jump to instruction code
 - Made restart code less different for different targets, and shorter for Plus/4 and C128. 
 - Optimized multiplication for input interrupt intervals, thus removing the last use of the generic 16-bit unsigned multiplication routine.
