@ -5,6 +5,8 @@ V1.0 (snapshot) - <date>
like a 68882/68040 FPU, eliminating the need for 68060 FPU patches
- added support for platform-independant mutexes, used by adb.cpp for
thread-safe mouse handling
- the TIME_OFFSET constant has been replaced by a (portable) function
TimeToMacTime(); file dates in ExtFS should now be correct
- Unix: windowed display mode supports different resolutions and color
depth, which can be switched on-the-fly
- Unix: Ctrl-F5 grabs mouse in windowed mode (enhanced compatibility
