macemu/BasiliskII/ChangeLog

V1.0 (snapshot) - <date>
	- added support for on-the-fly video resolution and depth switching,
	  and gamma tables

	  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
	- 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
	  with games like flight simulators)
	- Unix: audio sample rate, bit depth and channel count are adjustable
	  in the MacOS "Sound" control panel

	- removed Windows sources from the source archive; a version of
	  these that actually compiles and works can be downloaded from
	  Lauri Pesonen's site
