V1.0 (snapshot) - <date>
|
||||
- added support for on-the-fly video resolution and depth seitching
|
||||
- fsave/frestore emulation under AmigaOS and NetBSD/m68k always behave
|
||||
like a 68882/68040 FPU, eliminating the need for 68060 FPU patches
|
||||
|
||||
V0.9 (release 0.9-1) - 31.May 2001
|
||||
- final adjustments for 0.9 release
