git tag -a) store extra metadata: tagger name, email, date, and a message. They are checksummed and are the recommended choice for releases.
Lightweight tags (git tag without -a) are just pointers to commits with no extra data. Use them for temporary or personal references. For public releases, always prefer annotated tags.
git push does not push tags. Use:
git push origin <tagname> – Push a single tag.git push --tags – Push all local tags to the remote.git push --follow-tags – Push only annotated tags that are reachable from pushed commits.1.0.0-alpha.1) – Early testing, may be unstable.1.0.0-beta.1) – Feature-complete but still under testing.1.0.0-rc.1) – Potentially final, last round of testing.1.0.0-alpha < 1.0.0.
v prefix (e.g., v1.0.0) is a widely adopted convention, especially in the Git and open-source community. It helps distinguish version tags from other tags.
