Releasing FieldCraft

Releases are deliberate. Development lands on main; pushing the chosen commit to the release branch builds every package and creates a draft GitHub Release; a maintainer verifies the draft and publishes it. Pushes to main and tags never start a release, and nothing bumps the version automatically. The workflow is .github/workflows/release.yml; the packaging scripts are in packaging/ and run the same way on a developer machine.

What a release contains

Platform	Files	Script
macOS 11+, universal (arm64 + x86_64)	fieldcraft-<v>-macos-universal.dmg (FieldCraft.app on a drag-to-Applications image), fieldcraft-cli-<v>-macos-universal.zip	packaging/macos/package.sh
Linux x86_64, glibc 2.35+	fieldcraft-<v>-linux-x86_64.tar.gz (bin/, share/), fieldcraft-<v>-linux-x86_64.AppImage	packaging/linux/package.sh
Windows x64	fieldcraft-<v>-windows-x64.zip (fieldcraft.exe, fieldcraft-cli.exe)	packaging/windows/package.ps1

Plus SHA256SUMS.txt and the notes from .github/release-notes.md followed by GitHub's generated list of changes. Every package carries README.md, LICENSE-MIT, LICENSE-APACHE, NOTICE and THIRD-PARTY-LICENSES.txt (on macOS in FieldCraft.app/Contents/Resources/Licenses). The application id is io.github.jyviko.fieldcraft: the macOS bundle id, the Linux .desktop entry and icon name, and the window's Wayland app_id / X11 class. The icons come from assets/app-icon: icon.icns and Assets.car (macOS 26 and later) in the app bundle, icon.ico embedded in fieldcraft.exe (apps/fieldcraft/build.rs), the iconset PNGs as the Linux hicolor icons.

Signing

macOS. When the repository has the secrets below, the app, the dmg and the CLI are signed with a Developer ID (hardened runtime, packaging/macos/entitlements.plist) and notarized, and the tickets are stapled. Without them the build is ad-hoc signed, which runs on Apple silicon but which Gatekeeper blocks on first launch until the user right-clicks › Open; a run warns about it, and the release notes say which of the two the draft contains.

Secret	What it is
APPLE_CERTIFICATE	The "Developer ID Application" certificate with its private key, exported as .p12 and base64-encoded (base64 -i cert.p12 | pbcopy)
APPLE_CERTIFICATE_PASSWORD	The .p12's password
KEYCHAIN_PASSWORD	Optional: the temporary CI keychain's password (random when unset)
APPLE_ID	The Apple ID used for notarization
APPLE_PASSWORD	An app-specific password for that Apple ID (appleid.apple.com › Sign-In and Security)
APPLE_TEAM_ID	The 10-character team id of the Developer ID

Add them with gh secret set <NAME> -R jyviko/fieldcraft. With the certificate but without the three notarization secrets the app is signed and not notarized. A dmg made locally with packaging/macos/package.sh is ad-hoc signed unless MACOS_SIGN_IDENTITY names an identity in the keychain.

Linux and Windows builds are not signed; the checksums are the integrity check. On Windows SmartScreen warns about an unsigned download (More info › Run anyway) until a code-signing certificate is added.

Choose and prepare the version

1. Look at the previous published release (gh release list -R jyviko/fieldcraft) and the changes since it, and choose one version for the batch: a patch for compatible fixes; a minor for new capabilities, and while on 0.x also for breaking changes (say what breaks in the notes); -rc.N for a release candidate. 1.0 is the owner's decision.
2. Set [workspace.package] version in the root Cargo.toml and run cargo update --workspace --offline, which changes only the workspace crates' versions in Cargo.lock. Land it on main through a pull request like any change, and let CI on main pass. Note the commit to release.

Build the draft

git fetch origin
git switch release                 # the first time: git switch -c release origin/main
git merge --ff-only origin/main
git push origin release

Only fast-forward release and never force-push it. The run builds the three platforms; when all succeed, the last job checks that every file is there, writes SHA256SUMS.txt and the notes, and creates the draft FieldCraft v<version> targeting the pushed commit. Pushing release again with the same version rebuilds and replaces the draft's files (its notes are kept). The job refuses a version whose tag exists or whose release is already published: bump the version instead.

Verify and publish

Publishing is a maintainer's call; an agent preparing a release stops at the draft.

1. Check the run succeeded for the intended commit and the draft targets it (gh release view v<version> -R jyviko/fieldcraft).
2. Download the assets into an empty folder (gh release download v<version> -R jyviko/fieldcraft), run shasum -a 256 -c SHA256SUMS.txt, and check every platform's files are there.
3. Smoke-test what you can run: open the dmg, drag the app to Applications, launch it with --sample cantilever; run fieldcraft-cli --version from the zip or tar.gz; on Linux run the AppImage; on Windows unzip and start fieldcraft.exe. Look at the run's logs for the platforms you could not try (each job checks its own package).
4. Edit the notes: what is new, fixes, breaking changes, known limitations. Keep the install and signing paragraphs; never claim signing the notes don't state.
5. Publish: gh release edit v<version> -R jyviko/fieldcraft --draft=false --latest (a release candidate: --draft=false --prerelease --latest=false). Publishing creates the tag at the draft's commit; never push release tags by hand.

Dry runs

gh workflow run release.yml -R jyviko/fieldcraft --ref <branch> builds every package and uploads them with the notes as the release-assets artifact of the run, without creating a release. -f draft=true creates or updates the draft, and is accepted on release only. Locally, packaging/macos/package.sh --arch aarch64 (or x86_64, universal) and packaging/linux/package.sh write to dist/release/.
