Is this the first tag created? No\n1.1.0rc0+gha\n```\n\n### Current behavior\n\nEven if a tag like 1.0.1rc0+gha` exists, Commitizen reports:\n\n```\nNo tag matching configuration could be found.\nPossible causes:\n- version in configuration is not the current version\n- tag_format or legacy_tag_formats is missing, check them using 'git tag --list'\n```\n\nIf answering No to “Is this the first tag created?”, Commitizen appears to compute from more history than expected instead of using 1.0.1rc0+gha:\n\n```\n? Is this the first tag created? No\n1.1.0rc0+gha\n```\n\n### Desired behavior\n\nIf the current tag is of the pattern `1.0.1rc0+gha`, cz should recognize it and properly bump to `1.0.1rc1+gha` when using `cz bump --prerelease rc --build-metadata gha  --get-next`\n\n### Screenshots\n\n_No response_\n\n### Environment\n\nCommitizen Version: 4.16.3\nPython Version: 3.14.6 (main, Jun 11 2026, 04:03:53) [Clang 22.1.3 ]\nOperating System: Linux\n","author":{"url":"https://github.com/theinditector","@type":"Person","name":"theinditector"},"datePublished":"2026-06-16T15:59:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2015/commitizen/issues/2015"}
