- Will Sowerbutts provided an updated flash4 v1.3.9
- Modified HBIOS to be more proactive about disabling interrupts on systems with interrupts disabled to avoid issues with applications that turn them on.
- Updated NABU default configuration to run under interrupt mode 2.

- Add Z280 interrupt mode 3 to INTTEST app
- Make application boot handle restart by using HBIOS restart in place
- Resolve multiple issues with HBIOS restart in place
- Moved the saving/restoring of the interrupt state to bracket each individual test instead of the entire application.
- Removed the IM n test because there is no way to save/restore it.
- Add a hack to TUNE application to avoid corrupting PSG R7 which is used by and critical to NABU.
- NABU default baud rate to 38400 to get file transfers working without flow control.
- NABU default to console on video instead of UART.
- Implement Interrupt Mode 2 (Mode 1 is still default)
- Implement interrupt driven keyboard support
- Improve UART keyboard driver to support interrupt driven flow control
- Additional HBIOS reorganization - no functional changes (in theory)
- Upgrade to v1.3.8 of FLASH4 from Will Sowerbutts
- Upgrade to FAT v1.1 based on input from Peter (@z80micro-mc)

Update CLRDIR with minor update from the author Max Scane to emphasize the need to type a capital Y to proceed. Thanks and credit to Max Scane for this application.
Adds CLRDIR to the Applications document.
- Rearranged HBIOS code to improve colocation of related code.
- Implemented macros to improve control over assembly diagnostic output.
- Improved handling of diagnostic LEDs.
- Improved application boot bank management.
- Implemented application boot for Z280 systems.
- Moved Z280_BNKSEL into proxy.
-
- Translate NABU special keys to standard RomWBW values to allow things like arrow keys to emit proper escape sequences within ANSI emulation.
- Add a simple, single byte buffer to avoid keyboard status returning a key is ready when it is only a special character that has no translation.
