Only generating the changelog manually using `cz ch` lets the bump succeed.\n\nThe error occurse in a bump chain `0.0.1` → `0.0.2` → `0.0.3-rc.0` → `0.0.3-rc.1`\n\nFurthermore, using prereleases, `cz changelog` always throw warnings like:\n\n`Invalid version tag: '0.0-2rc.0' does not match any configured tag format`\n\nIt seems that the git tag is not parsed correctly when using custom tag_format and semver2.\n\nSee a szenario in steps to reproduce.\n\n### Steps to reproduce\n\n1. Initialize git project and place cz configuration:\n```\ngit init .\ncat \u003c\u003c EOF | tee cz.toml\n[tool.commitizen]\nname = \"cz_conventional_commits\"\ntag_format = \"\\${major}.\\${minor}-\\${patch}\\${prerelease}\"\nversion_scheme = \"semver2\"\nversion = \"0.0.1\"\nupdate_changelog_on_bump = true\nEOF\n```\n2. Create a first commit\n```\necho \"# test\" | tee README.md\ngit add README.md cz.toml\ngit commit -m \"fix: Add readme file\"\n```\n3. Bump a prerelease\n```\ncz bump --prerelease rc --yes\n```\n4. Add changes, commit and create changelog\n```\necho \"Some changes\" | tee -a README.md\ngit add README.md\ngit commit -m \"fix: Add changes to readme file\"\n```\n5. Try to bump another prerelease version (**failing**)\n```\ncz bump --prerelease rc --yes\n```\n5. Generate changelog (**succeeding with warning**)\n```\ncz changelog\n```\n6. Try to bump prerelease version again (**succeeding**)\n```\ncz bump --prerelease rc\n```\n\n### Current behavior\n\nBumping without prior changelog generation fails with: \n\n`Invalid version tag: '0.0-2rc.0' does not match any configured tag format`\n\nOnly if the changelog is created before bumping (so that `# Unreleased` heading appears) let's you create a bump.\n\nFurthermore commitizen does not recognize custom tags with prerelease part correctly, resulting in warnings using `cz changelog` like: \n\n```\nInvalid version tag: '0.0-2rc.1' does not match any configured tag format\nInvalid version tag: '0.0-2rc.0' does not match any configured tag format\n```\n\n\n### Desired behavior\n\n1. Changelog generation shall recognize the tags using custom tag_format with `${prerelease}`\n2. Bumping with changelog creation shall succeed without generating changelog before\n\n### Screenshots\n\nn/a\n\n### Environment\n\nCommitizen Version: 4.9.1\nPython Version: 3.9.21 (main, Aug 19 2025, 00:00:00) \n[GCC 11.5.0 20240719 (Red Hat 11.5.0-5)]\nOperating System: Linux","author":{"url":"https://github.com/pydal","@type":"Person","name":"pydal"},"datePublished":"2025-09-18T09:23:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1614/commitizen/issues/1614"}
