Release Process

This document is for maintainers releasing new versions of RustNet.

Changelog Maintenance (ongoing, not at release time)

Notable changes are added to the ## [Unreleased] section of CHANGELOG.md in the same PR that makes them — don't wait until release time and reconstruct the list from git history. Cutting a release then just renames that section (see step 3 below). pre-release-check.sh warns if [Unreleased] still has content after the rename, and the release workflow's notes extraction ignores it.

Creating a New Release

1. Run Pre-Release Checks

After updating versions and changelog, run the pre-release validation script:

./scripts/pre-release-check.sh 1.2.0

This validates version consistency, changelog entries, code quality (fmt/clippy/test), Dockerfile correctness, and git status. Fix any errors before proceeding.

2. Test Platform Builds

Before tagging, verify all platform builds succeed on the current main branch:

# Ensure you're on the main branch with latest changes
git checkout main
git pull origin main

1. Go to Actions > Test Platform Builds
2. Click "Run workflow"
3. Select all to test all platforms (including static Linux builds)
4. Wait for the workflow to complete successfully

This catches cross-platform and static linking issues before you invest time in release prep.

3. Prepare the Release

Two version tracks since the workspace split. Cargo.toml carries two versions: the binary's [package] version (line ~30, the user-facing 1.x line that tags and packages follow) and [workspace.package] version (line ~9, the 0.x library crates rustnet-core/-capture/-host, single source of truth also referenced from [workspace.dependencies]). A normal feature release bumps only the binary [package] version and rpm/rustnet.spec. Bump the library version separately, and only when the libraries actually change in a release-worthy way.

Update the binary version in Cargo.toml and rpm/rustnet.spec, and turn the accumulated [Unreleased] changelog section into the release entry:

# Update Cargo.toml [package] version (e.g., version = "1.4.0") — NOT the
#   [workspace.package] version unless you intend to bump the library crates.
# Update rpm/rustnet.spec Version field (e.g., Version: 1.4.0)

# In CHANGELOG.md:
#   1. Rename "## [Unreleased]" to "## [0.3.0] - YYYY-MM-DD" (review/polish the entries)
#   2. Add a fresh, empty "## [Unreleased]" section above it
#   3. Update the comparison links at the bottom:
#        [Unreleased]: https://github.com/domcyrus/rustnet/compare/v0.3.0...HEAD
#        [0.3.0]: https://github.com/domcyrus/rustnet/compare/v0.2.0...v0.3.0

# Update Cargo.lock and test the build
cargo build --release
cargo test

4. Commit Release Changes

# Stage and commit the version and changelog changes
git add Cargo.toml Cargo.lock CHANGELOG.md rpm/rustnet.spec
git commit -m "Release v0.3.0

- Feature or fix summary here
- Another change here
- And more changes"

5. Create and Push Git Tag

# Create an annotated tag matching the version in Cargo.toml
git tag -a v0.3.0 -m "Release v0.3.0

- Feature or fix summary here
- Another change here
- And more changes"

# Push both the commit and the tag
git push origin main
git push origin v0.3.0

That's it! The GitHub Actions workflow will automatically:

• Build binaries for all platforms (Linux, macOS, Windows - multiple architectures)
• Create installer packages (DEB, RPM, DMG, MSI)
• Extract release notes from CHANGELOG.md
• Create a draft GitHub release with all artifacts attached
• Upload all binaries and installers to the release
• Publish the release (un-draft) once all assets are uploaded
• Trigger downstream package updates (Homebrew, Chocolatey, FreeBSD, PPA, COPR, AUR, Docker, crates.io)

6. Verify the Release

Once the GitHub Actions workflow completes (~15-20 minutes):

1. Go to the GitHub repository releases page
2. Verify the release is published (no longer a draft) with all assets
3. Review the automatically extracted release notes
4. Check downstream package updates completed (Homebrew, Chocolatey, etc.)

Automated Release Workflow

The release process is fully automated via .github/workflows/release.yml:

Triggers:

• Pushing a tag matching v[0-9]+.[0-9]+.[0-9]+ (e.g., v0.3.0, v1.2.3)
• Manual workflow dispatch

What it does:

1. Builds cross-platform binaries:

   • Linux: x64, ARM64, ARMv7 (with eBPF support)
   • macOS: Intel (x64) and Apple Silicon (ARM64)
   • Windows: 64-bit and 32-bit

2. Creates installer packages:

   • Linux: DEB packages (amd64, arm64, armhf) and RPM packages (x86_64, aarch64)
   • macOS: DMG installers with app bundles (supports code signing/notarization if secrets configured)
   • Windows: MSI installers (64-bit and 32-bit)

3. Extracts release notes:

   • Automatically parses CHANGELOG.md to extract the version-specific section
   • Falls back to auto-generated notes if no changelog entry is found

4. Creates GitHub release:

   • Creates a draft release with the tag name as title
   • Attaches all binaries and installer packages
   • Uses extracted changelog content as release notes

5. Publishes the workspace to crates.io (via .github/workflows/publish.yml, after the GitHub release is published): the four crates are published in dependency order — rustnet-core → rustnet-capture → rustnet-host → rustnet-monitor — waiting for each to appear in the index before publishing a dependent. The step is idempotent (it skips any crate@version already on crates.io), so a re-run after a partial failure is safe. The library crates use the [workspace.package] version; the binary uses its [package] version.

Important: Never Move a Tag After Release

Never force-push or move a tag after the release pipeline has started. Moving a tag causes GitHub to regenerate source tarballs with different SHA checksums, which breaks every downstream package manager that already cached the original checksums:

• AUR/Homebrew/Chocolatey: checksum verification failures for end users
• Launchpad PPA: rejects uploads with the same version but different file contents
• crates.io: already published and cannot be re-published with the same version

If a fix is needed after tagging, create a patch release (e.g., v1.1.1) instead.

Release Checklist

Before pushing the tag, ensure:

• Pre-release checks pass: ./scripts/pre-release-check.sh x.y.z
• Test Platform Builds workflow passes for all platforms (including static)
• Binary version updated in Cargo.toml [package] (not [workspace.package] unless bumping the library crates)
• Version number updated in rpm/rustnet.spec (line 5: Version: x.y.z)
• Cargo.lock updated (via cargo build)
• CHANGELOG.md: [Unreleased] renamed to ## [x.y.z] - YYYY-MM-DD, a fresh empty [Unreleased] added, comparison links updated
• All tests pass (cargo test)
• Changes committed to main branch
• Git tag created and pushed

After GitHub Actions completes:

• Verify release is published (automatically un-drafted after all assets uploaded)
• Verify all platform binaries built successfully
• Verify all installer packages created (DEB, RPM, DMG, MSI)
• Verify Docker image pushed to ghcr.io
• Verify all four crates published to crates.io (rustnet-monitor, rustnet-core, rustnet-capture, rustnet-host) and docs.rs built
• Review automatically extracted release notes
• Verify Homebrew formula updated at https://github.com/domcyrus/homebrew-rustnet
• Verify Chocolatey package updated at https://github.com/domcyrus/rustnet-chocolatey
• Verify FreeBSD build at https://github.com/domcyrus/rustnet-bsd
• Announce release (if applicable)

Maintenance: New Ubuntu and Fedora Releases

This is an occasional task, not part of every release. When a new Ubuntu interim or LTS, or a new Fedora release, is published and we want RustNet packages to ship for it:

1. Ubuntu PPA: add the new codename to the matrix in .github/workflows/ppa-release.yml (the set-matrix job's releases=[...] list and the workflow_dispatch choice options). Confirm the new series ships rustc-1.88 (or whatever the current rust-version floor in Cargo.toml is). Reference: issue #254 added Ubuntu 26.04 (Resolute) support.
2. Fedora COPR: add the new chroot in the COPR project settings at https://copr.fedorainfracloud.org/coprs/domcyrus/rustnet/edit/. The chroot list is managed in the COPR UI, not in this repo.
3. Trigger a workflow_dispatch of Release to Ubuntu PPA for the new codename to verify the build before relying on it from the next tagged release.

Conversely, when an older Ubuntu series is no longer worth supporting (no rustc-1.88 in archive, or end of life), remove it from the same two locations and update INSTALL.md and debian/README.md to match.

Versioning

RustNet follows Semantic Versioning (SemVer):

• MAJOR version for incompatible API changes
• MINOR version for backward-compatible functionality additions
• PATCH version for backward-compatible bug fixes

Examples:

• v0.1.0 → v0.1.1 (bug fixes)
• v0.1.1 → v0.2.0 (new features)
• v0.2.0 → v1.0.0 (major changes, API stability)
