From 47c9b0a281c0b6c8ebf444bfe732383fe7b6ef1a Mon Sep 17 00:00:00 2001 From: openhands Date: Fri, 6 Mar 2026 22:10:46 +0000 Subject: [PATCH 1/5] Add release notes generator plugin This plugin generates consistent, well-structured release notes from git history. It can be triggered via GitHub Actions on release tags following semver patterns (e.g., v*.*.*) or manually invoked. Features: - Automatic tag detection: Finds previous release tag to determine commit range - Categorized changes: Groups into Breaking Changes, Features, Bug Fixes, Docs, Internal - Conventional commits support: Categorizes based on commit prefixes (feat:, fix:, etc.) - PR label support: Also categorizes based on GitHub PR labels - Contributor attribution: Includes PR numbers and author usernames - New contributor highlighting: Identifies first-time contributors - Flexible output: Updates GitHub releases or generates CHANGELOG.md entries Closes #97 Co-authored-by: openhands --- plugins/release-notes/README.md | 251 +++++++++ plugins/release-notes/SKILL.md | 81 +++ plugins/release-notes/action.yml | 91 ++++ .../scripts/generate_release_notes.py | 501 ++++++++++++++++++ plugins/release-notes/skills/releasenotes | 1 + .../release-notes/workflows/release-notes.yml | 75 +++ tests/test_release_notes_generator.py | 360 +++++++++++++ 7 files changed, 1360 insertions(+) create mode 100644 plugins/release-notes/README.md create mode 100644 plugins/release-notes/SKILL.md create mode 100644 plugins/release-notes/action.yml create mode 100644 plugins/release-notes/scripts/generate_release_notes.py create mode 120000 plugins/release-notes/skills/releasenotes create mode 100644 plugins/release-notes/workflows/release-notes.yml create mode 100644 tests/test_release_notes_generator.py diff --git a/plugins/release-notes/README.md b/plugins/release-notes/README.md new file mode 100644 index 0000000..a0a9b30 --- /dev/null +++ b/plugins/release-notes/README.md @@ -0,0 +1,251 @@ +# Release Notes Generator Plugin + +Automated release notes generation using OpenHands agents.

comments MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. Remove unused requests dependency from action.yml (script uses stdlib urllib) 2. Remove __future__ annotations import (unnecessary for Python 3.12 target) 3. Fix semver regex with proper end anchor to avoid matching 'v1.2.3abc' 4. Add error logging to exception handlers instead of silently swallowing - get_pr_for_commit: logs warning when PR fetch fails - is_new_contributor: logs warning when contributor check fails - get_tag_date: logs warning when tag date fetch fails 5. Refactor main processing loop into separate helper functions: - _process_commit: handles single commit → Change conversion - _categorize_changes: categorizes list of changes - _process_contributors: extracts and identifies contributors 6. Fix regex to require colon delimiter to avoid stripping legitimate content (e.g., 'BREAKING change in...' won't be incorrectly stripped) Co-authored-by: openhands --- plugins/release-notes/action.yml | 5 -
