For Tock 1.4 we had five milestones for the release:
- #1230 (Docs: Add README.md to /libraries/enum_primitive)
- #1215 (Tracking: Unified Course)
- #1167 (UART HIL re-design)
- #1233, #1297 (GPIO HIL re-design)
- #1234 (Time HIL re-design)
The major changes are around updating HIL interfaces (UART, Time, and GPIO). Other changes include:
- Initial support for RISC-V architectures.
- Update to Userland-Kernel boundary interface.
- Add nucleo-based boards.
- Add ACD52832 board.
