New in Version 2.5

• Fixed a bug that suppressed an immediate interrupt at the drive CPU when the ATN line went down. This bug was the cause of the Action Replay fast loader problem.
• The disk encoder used a wrong sector ordering. It arranged the sectors similar to a PC floppy drive (physical interleaving) which is wrong for the VC 1541.
• Fixed VICE test drive/skew.prg by adjusting the tail gap values the disk encoder uses.
• Now passing VICE test irq-ack-vicii.prg. This bug bix makes the Vandalism demo work well.
• Now, the virtual keyboard can be opened via the keyboard menu, too. If it is opened that way, it is displayed as a separate window and won't close automatically when a key is pressed.
• In the previous release, the G64 mount dialog ignored the selected target drive. G64 disks were always inserted into drive 2. This has been fixed.
• If the emulator fails to build a GPU compute kernel (upscaler or filter), the corresponding option is grayed out in the emulator preferences. Previous versions crashed in this case.

New in Version 2.4

• Added a virtual keyboard to the toolbar.
• Added a second VC 1541 drive to the virtual hardware.
• Added support for the Freeze Frame cartridge.
• Fixed a bug that prevented the fast loader of the Action Replay 4 cartridge to work properly. AR cartridges with higher version numbers still have issues though.

New in Version 2.3

• Added support for the GeoRAM memory extension cartridge.
• Added a sleep logic to the virtual VIA chips that partly compensates the performance loss showing up in Version 2.2 due to the more accurate drive emulation.
• Added experimental support for the ActionReplay cartridge. Please note that the AR fast loader does not work yet.
• Fixed a bug that prevented the emulator state to be restored accurately when loading from a snapshot file.
• Added some more options to the Drive, Tape, and Cartridge menus for conveniently accessing previously used files.

New in Version 2.2

• Emulation of the VC1541 disk drive has been improved considerably. The emulator is compatible with various fast loaders now. Before updating, please note that the higher accuracy results in a reduction of the maximum emulation speed (warp mode) by approx. 25 percent. I hope to be able to restore the old emulation speed in one of the next releases.
• Added an option to the emulator preferences to disable the auto-snapshot feature.
• Fixed a bug that caused the drive to enter write mode after a reset.

New in Version 2.1

• Now passing VICE test openio/de00int and all tests in the irqdma test suite.
• Fixed a bug in the implementation of the LSR command.
• The floppy drive's clocking logic has been improved. A couple of demos that did not work in the previous release can be loaded smoothly now.
• Some minor GUI issues have been fixed.
