Releasing MarkdownViewr

Releases follow the KofTwentyTwo release standard. Pushing a protected v* tag on main runs .github/workflows/release.yml, which calls the shared release-velopack.yml workflow in KofTwentyTwo/standards.

Workflow baseline

The signing release builder is pinned to standards v1.1.0 (93b1d6163a4c466ae443e98b62786fc4d80d33bd); other shared gates retain v0.1.2. The release caller checks main ancestry and reruns build, coverage, formatting, UI tests, security scans and CodeQL before publication. The AppKit dependency locks now match the published 0.1.0 packages. Before changing any package version, regenerate the affected locks and verify a locked restore with a clean package cache.

Versioning and channels

The version is the tag without the leading v, in strict semver.

Tag	Version	GitHub Release	Velopack channel
v1.2.3	1.2.3	stable	stable
v1.2.3-beta.1	1.2.3-beta.1	prerelease	dev

An installed copy only updates within its own channel. Directory.Build.props holds VersionPrefix, the next expected release; local builds are <prefix>-dev. Bump it in a pull request right after each release.

Run the installed channel smoke test before releasing. It verifies real stable/dev upgrades and published-output startup with local fixtures.

What a release does

The shared workflow (SLSA Build L3: the build definition lives in KofTwentyTwo/standards):

1. Validates strict SemVer and repeats locked restore, zero-warning build, unit tests, and the 100% coverage gate.
2. Publishes the app unpackaged and self-contained (and the single-file command line), signs the owned binaries and packs them with Velopack: Setup, portable zip, full and delta update packages.
3. Generates CycloneDX SBOMs, writes SHA256SUMS, and attests provenance and SBOMs.
4. Creates a draft GitHub Release with every asset and generated notes, then publishes it (releases are immutable).

The optional winget job in release.yml then submits the manifest update for stable releases.

Optional Scoop/Chocolatey candidate generation supports CLI and GUI portable payloads, using final-byte hashes and verified provenance. Follow the distribution presets; no package feed is updated by default.

One-time setup (owner)

1. Environment release (Settings → Environments) with a deployment rule that allows only tags matching v*.
2. Code signing: complete the signing configuration, pin its published reviewed builder, then enable sign: true with an explicit owned-file catalog. The preflight blocks unsigned publication and incomplete protected-environment configuration before any release build starts.
3. winget (optional): submit the first stable release by hand with wingetcreate new, then add WINGET_TOKEN to the release environment and the repository variable WINGET_PACKAGE_ID.

Cutting a release

1. Make sure main is green and the conformance check passes: pwsh ../standards/tools/Test-RepoConformance.ps1 -Repository KofTwentyTwo/MarkdownViewr.Windows -LocalPath .

2. For a minor or major release, open a release checklist issue from the standards template and complete it (security assessment, threat model review, scan results).

3. Tag main and push the tag:

   git switch main
   git pull
   git tag -s v0.1.0 -m "v0.1.0"
   git push origin v0.1.0
   

4. Watch the release workflow, then verify the release as described in the developer guide.

5. Open a pull request that bumps VersionPrefix in Directory.Build.props.

When something fails

• Before the release is published: nothing is public. Delete the draft (gh release delete v0.1.0 --yes), fix the cause, and re-run the workflow.
• A published release is broken: never reuse its version; installed copies may have seen it. Fix forward with a new patch release.
