Releasing

Releases are automated by release-plz. You do not run cargo publish, edit versions, write changelog entries, or push tags by hand.

How it works

Merge a PR to master using conventional commits (feat:, fix:, perf:, refactor:, docs:, chore:, or a ! / BREAKING CHANGE: footer for a major bump).
.github/workflows/release.yml opens or updates a chore: release vX.Y.Z PR. It contains the semver bump in [workspace.package], the refreshed Cargo.lock, and the generated CHANGELOG.md entry. Review it like any other PR.

Merging that PR releases, but only once CI has passed on the merge commit — a published crates.io version can be yanked but never withdrawn, so the Wait for CI job blocks the publish until the CI run for that exact commit is green:

tags vX.Y.Z and creates the GitHub release with the changelog as its notes,
publishes soulseek-rs-lib then soulseek-rs to crates.io (dependency order, waiting for the index between them),

builds and attaches binaries with .sha256 checksums for six targets:

Archive	Notes
`soulseek-rs-vX.Y.Z-x86_64-unknown-linux-musl.tar.gz`	static, any glibc
`soulseek-rs-vX.Y.Z-aarch64-unknown-linux-musl.tar.gz`	static, any glibc
`soulseek-rs-vX.Y.Z-x86_64-apple-darwin.tar.gz`	Intel Mac
`soulseek-rs-vX.Y.Z-aarch64-apple-darwin.tar.gz`	Apple Silicon
`soulseek-rs-vX.Y.Z-x86_64-pc-windows-msvc.zip`
`soulseek-rs-vX.Y.Z-aarch64-pc-windows-msvc.zip`

rewrites Formula/soulseek-rs.rb in the michel/homebrew-tap repository so brew install michel/tap/soulseek-rs picks up the new macOS and Linux archives.

Both crates always share one version, one tag, and one changelog — see release-plz.toml.

Nightly builds

.github/workflows/nightly.yml builds the tip of develop at 02:17 UTC every day. It resolves the commit once, builds the same six targets as a numbered release, verifies all twelve archives and checksum files as one set, then replaces the mutable nightly prerelease and tag. The published release is smoke-tested through both the curl and wget installer paths.

Use Actions → Nightly → Run workflow to force a build. The workflow always checks out develop, regardless of the ref selected in the dispatch form. The equivalent command is:

gh workflow run nightly.yml --ref develop

Nightly does not publish crates or update Homebrew. If a target fails, the previous nightly release stays available; use a manual run to retry.

One-time repository setup

Settings → Actions → General → Workflow permissions: enable Allow GitHub Actions to create and approve pull requests. Without it the release PR is never opened.
Settings → Secrets and variables → Actions: add CARGO_REGISTRY_TOKEN, a crates.io token scoped to publish-new and publish-update. Without it the tag and GitHub release still happen, but the crates.io publish fails.
Homebrew tap: create a public michel/homebrew-tap repository, then add a HOMEBREW_TAP_TOKEN secret — a fine-grained PAT with Contents: read and write on that repository only. GITHUB_TOKEN cannot reach another repository. The formula itself is generated by the workflow; nothing in the tap needs editing by hand.

Notes

A merge with no releasable commits (only docs:/chore:/test:) opens no release PR. That is intended.
The release PR does not run CI on its own, because GitHub does not trigger workflows for PRs opened with GITHUB_TOKEN. Pushing any commit to that branch yourself does start it — handy if you want the version bump validated before merging.
If one target's build fails, the other five still upload (fail-fast: false). To retry, run the Release workflow manually and set tag to the existing tag (e.g. v6.0.0); it rebuilds and re-uploads every target for that tag. Re-running the failed job from the Actions UI replays the old workflow file, so it is no use when the workflow is the thing that needs fixing.
To skip a release for a commit that would otherwise trigger one, use a chore: type.
If CI flakes on the release commit the publish is blocked, by design. The e2e suite talks to a real soulfind server over the network and does occasionally time out. To recover: re-run the failed CI job, wait for that run to go green, then re-run the Release workflow. The gate reads the newest CI run for the commit, so it will then pass. Never work around it by publishing by hand.
Release binaries are stripped via [profile.release] strip = true in the workspace Cargo.toml, so cargo install benefits too — not just the release archives.

Installing a release

cargo install soulseek-rs

Or download an archive from the releases page, verify it against the adjacent .sha256, and extract the binary.
