f469-disco

Release Procedure

Releases are automated via GitHub Actions. Pushing a version tag triggers a build and creates a GitHub release.

Creating a Release

git tag v1.4.0
git push origin v1.4.0

What Happens

1. GitHub Actions checks out code with submodules
2. Builds mpy-cross, disco, empty, and unix targets
3. Runs tests
4. Creates release with:
   • upy-f469disco.bin - firmware with frozen bitcoin library
   • upy-f469disco-empty.bin - minimal firmware
   • Auto-generated release notes from commits

Version Format

Tags must match vX.Y.Z pattern (e.g., v1.4.0, v2.0.0-beta).
