This is an important release. No new boards, but we make up for that by adding a bunch of other big stuff!

Some of the highlights:

  • Go 1.23 support (including the new range-over-func language feature)
  • WASI preview 2 support
  • MIPS little endian support (big endian support is still experimental), so you can use GOARCH=mipsle
  • softfloat support for ARM and MIPS
  • improved error messages

For a full list of changes, see the list below.

  • general
    • use latest version of x/tools
    • add chromeos 9p support for flashing
    • sort compiler error messages by source position in a package
    • don't include prebuilt libraries in the release to simplify packaging and reduce the release tarball size
    • show runtime panic addresses for tinygo run
    • support Go 1.23 (including all new language features)
    • test: support GOOS/GOARCH pairs in the -target flag
    • test: remove message after test binary built
  • compiler
