Edition

The specification as published on semver.org, built from spec/v2.0.0.md of github.com/semver/semver.org (last changed on 7 May 2023); the home page semver.org shows the same text. Since then the master branch of github.com/semver/semver has changed four places (“(build metadata” and “major, minor” in rule 11, “release a new patch version” and “probably an overkill” in the FAQ): the poster follows semver.org. The title of the page is the title of the poster; links are set as plain text; the grammar runs across the page in two columns and the two regular expressions wrap at the width of their column. No bundled font has the horizontal bar (U+2015) of the License section: it stays in text.md and is drawn as a rule one em long (style.css). The date of the kicker is date-released in CITATION.cff of github.com/semver/semver.
