Building a new Ruby release

ruby build.rb [ruby|jruby|truffleruby] VERSION

Process for new builds

When making builds a different way, first create a new release and mark it as prerelease.

Then if it might cause breaking changes, open an issue on actions/virtual-environments with a description of the changes. This needs to be done 2 weeks prior to using the release.

Once it's ready, mark the release as non-prerelease and switch to it in ruby/setup-ruby.

Naming

Archives are named $engine-$version-$platform.tar.gz.

platform is one of:

• ubuntu-NN.NN: built on the corresponding GitHub-hosted runner virtual environment
• macos-latest: built on macos-13, the oldest macos-amd64 available on GitHub-hosted runners.
• macos-13-arm64: built on macos-14, the oldest macos-arm64 available on GitHub-hosted runners.
• windows-latest: built on windows-2019 (does not matter, it's only for repacking a JRuby archive, no actual build)

The names contain -latest for compatibility, even though what -latest points to for runners might have changed.
