`docs/release.md` had the maintainer build both gems locally and push them by hand: `rake release` for the `ruby` one, and a Docker image for the `java` one because it needs the WASI SDK to compile `rbs_parser.wasm`. That is a lot of laptop for something that has to be reproducible, and it puts the RubyGems credentials of whoever runs it in the path. `Release gems` does it instead. Dispatched against a `vX.Y.Z` tag it builds both gems, checks them, pushes them to RubyGems through trusted publishing, and publishes the GitHub release. A release is now a pull request, a tag, and one workflow run. The `java` gem is built on CRuby rather than in the JRuby image: the platform comes from `RBS_PLATFORM`, not from the engine running `gem build`, so all the image was providing is the WASI SDK -- which the `wasm` and `jruby` workflows already install directly. JRuby is still needed to *run* the result, so the workflow installs the built gem on JRuby and parses with it. That is the check metadata cannot make: a stale or broken wasm module only shows at require time. Publishing is ordered so that the reversible step always comes first. The tag is created before the workflow runs; the artifacts are uploaded before the push, so a failed push still leaves the gems behind; and the GitHub release comes last, so a failed push never announces a release that has no gems. The trusted publisher has no environment, so the dispatched ref is the only thing deciding what gets published. The workflow refuses to publish unless the tag matches `RBS::VERSION`, and dispatching against a branch builds and stops. `gem:gh_release` takes the notes from the topmost CHANGELOG.md section and is skipped for `.dev.N` versions, which are cut from the development line and are not written up. It reads the file as UTF-8 explicitly: the default external encoding follows the locale, which is C on the runners. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Building both gems and pushing them by hand —
rake releasefor therubyone, a Docker image for thejavaone because it needs the WASI SDK — moves to aRelease gemsworkflow: dispatched against avX.Y.Ztag it builds both gems, installs thejavaone on JRuby and parses with it, pushes both to RubyGems through trusted publishing, and publishes the GitHub release.A release is now a pull request, a tag, and one workflow run;
docs/release.mdis rewritten around that, including what the three kinds of release (X.Y.Z,.pre.N,.dev.N) each get written up as.
