tinygo-org/tinygo v0.32.0

0.32.0

on GitHub

This release has lots of features and fixes that you need. From support for the new LLVM 18, to a patched version of the go/ssa package with a fix for the race condition that annoys anyone who maintains a CI build using TinyGo. Of course, no TinyGo release would be complete without new hardware supported, such as the Pimoroni Badger2040-W. And more WASM features too!
