Use when publishing a new library version — bumping the version, tagging, creating a GitHub release — or when asked what remains before a release can be tagged.

Use when changes to src/ or examples/ need compile verification before committing, when asked to build or verify the library, or when arduino-cli is not installed on this machine ("arduino-cli not found").
Use when a public method is added, removed, or its signature changed, before committing API changes, or when asked to audit consistency between the header, cpp, README and keywords.txt.

| description | Use when publishing a new library version — bumping the version, tagging, creating a GitHub release — or when asked what remains before a release can be tagged. |
The Arduino Library Manager indexes this library by git tags, so a wrong tag is
effectively immutable — never delete or move a pushed tag; fix mistakes with a new
patch release. The version lives in two places that must match: library.properties
(version=) and the tag name. Tag format is bare x.y.z (no v prefix — must
match the existing 1.0.0 tag).
git status shows a clean tree; the release commit
is on master (feature work happens on dev, releases are tagged on master).version= in library.properties equals the intended x.y.z
(SemVer: breaking = major, new API = minor, fixes = patch).CHANGELOG.md has a ## [x.y.z] - YYYY-MM-DD section with the
release date and content matching what is actually being shipped.gh run list --branch master --limit 3.
An empty list also fails this check — it means CI has never run on that commit
(e.g. the workflow was never pushed); wait for a green run, don't assume one.Any precondition failing → stop and report what's missing; do not tag.
git tag x.y.z # on the release commit on master
git push origin x.y.z
gh release create x.y.z --title "x.y.z" --notes "<the x.y.z section from CHANGELOG.md>"
The Library Manager picks up the new tag automatically (the repo is registered in its
index; arduino-lint runs in CI with library-manager: update to guard compliance).
| Mistake | Consequence / fix |
|---|---|
Tag v1.2.0 instead of 1.2.0 | Inconsistent with 1.0.0; Library Manager treats it as a different scheme. Use bare x.y.z. |
Tagging with library.properties still on the old version | Library Manager publishes the tag with the wrong version string. Bump first, tag second. |
| Deleting/re-pushing a bad tag | The index may have already picked it up. Publish a new patch version instead. |
Tagging on dev | The tagged tree may differ from master. Merge first, tag the merge commit. |
