Added

• Power button (#317) default action is now a clean shut down (requesting the guest to shut down). Shift+click reboots, Ctrl+click cuts power.
  • Linux handles this through a new poweroff/reboot driver.
  • On a Z80 the button falls back to a hard stop or restart.

Changed

⚠️ Really breaking ⚠️

Shut down computers before updating. If you copied the bundled Lua/MicroPython libraries to a drive, those must be replaced with the new versions.

• HLAPI (RPC) protocol changed (multi-blob support, checksums are now CRC32). This is why the libs need updating.
• MLAPI memory address changed
  • RISC-V: moved from 0x03000000 to 0x10000000.
  • Z80: now comes after other built-in devices, so its port has changed.
• Interrupts: dynamically assigned interrupts are now allocated from high to low. New system controller interrupt uses 7, so this can conflict with saved state.
• Finding devices by name now takes a list of names and returns the devices that match all of them (#316):
  • Lua bus:find(...) and Python bus.find(*names).
  • C mlapi_find(nth, name, ...) (argument order changed).
  • Z80 OCFIND takes a list of names ending in a double zero byte.
  • The C helper names were also changed to match the Z80 library.

All of this just to make clear: don't be surprised if things break during this upgrade. It's a bit of a pain, but it's some direly needed cleanup that should also avoid such breakages going forward.

Fixed

• Fixed a client crash when enchanted armor or elytra is rendered in the projector depth pass (#325).
• Fixed the world flickering near a projector while it rains (#321).
• Clean reset of the RISC-V board on reboot. The HLAPI state now also resets on boot.
