testLandingKeepsTheHistoryOfItsReleases

tcmts.cli.test.e2e.merge.testLandingKeepsTheHistoryOfItsReleases · #cimbqb5i · term

A branch that made a release lands with its history, squashed or not: the release is an entry of the branch's, so main's next release follows it, and a push of main carries it.
