What's New:

New features
- New dialog for creating Flash images, which is also available in the Mobile UI!
- Running as 64bit application on Windows is supported now
- Polish translation is available now
- CX II (/-T/CAS) calculators can now be emulated! However, with the current dumping programs you will not get a complete bootrom and booting the OS will fail.

Improvements
- Multiple files can be sent in the Mobile UI and by dropping them into the main window on desktop
- Reimplemented emulation speed control: Now it's more accurate, especially on Windows
- GitHub actions now performs automated builds for Android (armeabi-v7a and arm64-v8a in one APK), macOS and Windows (32bit and 64bit) on releases and pull requests
- The "installer" for OS 4.5.3.14 (and later?) works now. It requires fastboot RAM to persist state across reboots, which is now implemented.
- More accurate emulation of the On button: It's now possible to enter Press-To-Test mode
- Faster saving and loading of snapshots
- More reliable USB file transfers
- The debugger console now includes entered commands in the log
- Support for PIE (position-independent executables) on x86_64. Previously, care needed to be taken that PIE was disabled, otherwise it would crash on start.
- Building the JIT is disabled automatically if the platform does not support it
- Firebird builds on FreeBSD
