This is a smaller but important release just in time for GopherCon US.

Some of the bigger changes of this release are switching to LLVM 16, fixes for two separate hard-to-reproduce compiler crashes, improvements to USB-MIDI, and added support for the Adafruit Gemma M0.

Here is the full list:

• general
  • add LLVM 16 support, use it by default
• compiler
  • build: work around a race condition by building Go SSA serially
  • compiler: fix a crash by not using the LLVM global context types
  • interp: don't copy unknown values in runtime.sliceCopy to fix miscompile
  • interp: fix crash in error report by not returning raw LLVM values
• standard library
  • machine/usb/adc/midi: various improvements and API changes
  • reflect: add support for [...]T → []T in reflect
• targets
  • atsamd21, atsamd51: add support for USB INTERRUPT OUT
  • rp2040: always use the USB device enumeration fix, even in chips that supposedly have the HW fix
  • wasm: increase default stack size to 32k for wasi/wasm
• boards
  • gobadge: add GoBadge target as alias for PyBadge :)
  • gemma-m0: add support for the Adafruit Gemma M0
