- Unique I/O configuration for Les Bird's Graphics/Sound/Joystick Module has been removed because the module now conforms to generic MSX port conventions.
- 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
- 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)

- 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.

- The post-reset delay of both the IDE and PPIDE drivers has been extended. The SD-IDE adapters need more time to initialize before being ready to behave as proper IDE devices.
- Added support for the FDC section of the Duodyne Disk-IO board.
- Credit and thanks to Martin R for providing a substantial list of suggested fixes and improvements to the User Guide. I have done my best to address them -- others will require more time and will hopefully be addressed in the future.
- Added support for Duodyne Multi-IO board
- Added support for Duodyne Zilog-IO board
- Added SUPCTS equate in hbios.asm to allow selectively adding code to suppress use of CTS during HBIOS boot
- Added reference in User Guide to Bruce Hall's Assembly Language Programming document
- Add minimal Fuzix instructions to User Guide
- Enable CTC auto-detect by default for RCBus. It causes no problems to auto-detect it and it will stop a CTC from generating unexpected interrupts after a soft restart.
- Upgrade `SUPERSUB` to v1.3 (previously v1.1)
Driver Device Type ID's have been stored in the upper nibble. However, running out of ID's, I have changed them to occupy the entire byte.
This is a breaking change, so I have updated the minor version number to maintain integrity between components. So, v3.3 will never become a stable release and I am moving directly to v3.4.
- Support is limited to 512 byte sectors. So, devices such as ATAPI Zip Drives will work. CD-ROM devices will not because they use a larger sector size.
IMM Driver has rational timeouts now. It also lights the MG014 LED during activity.
The PPA skeleton just attempts to determine if the PPA interface is present. It does not attempt any I/O.
