From 4e4d574f38c5f65aa5bb1e1dcb798d7bbe6d886d Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Fri, 17 Apr 2026 18:29:19 -0400 Subject: [PATCH] Document towncrier changelog workflow in CONTRIBUTING.md and README.md MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both documents still told contributors to edit `changelog_entry.yaml` and run `make changelog`. Both have been deprecated for some time — the Versioning workflow runs towncrier on merge to compile fragments from `changelog.d/` into `CHANGELOG.md` and bump the version automatically. Contributors who follow the stale instructions hit the PR CI's "Check changelog fragment" step, which rejects branches that only have `changelog_entry.yaml`. Rewrites the "Changelog entries" / "Step 3: Changelogging" sections in both files with the fragment-type table and an `echo ... > changelog.d/...` example.

If you're new to the project, go to **Issues** and search for good first issues `label: "good first issue"`. If you see an open issue that no one's opened a PR against, it's all yours! Feel free to make some edits, then open a PR, as described below. - -## Developing - -Keep your fork's `master` branch in sync with the original repo by pulling the original repo's code at times; typically (if the original repo is called "upstream" by Git) this means running `git pull upstream master`, then `git push origin master` to sync the code to your local repo. - -Create branches on your fork off of your master or main branch. Periodically, if you're working on something for a while, you might also run `git rebase master` within your feature branch to sync your code with any new changes. - -## Testing, Formatting, Changelogging - -You've finished your contribution, but now what? Before opening a PR, we ask contributors to do three things. - -### Step 1: Testing - -To test your changes against our series of automated tests, run +```bash +# Install dev dependencies (uses uv) +make install -``` +# Run the full test suite make test -``` -We also ask that you add tests for any new features or bug-fixes you add, so we can gradually build up the code coverage.

This changelog is formatted in YAML and describes the changes you've made to the code. This should follow the below format: - -``` -- bump: {major, minor, patch} - changes: - {added, removed, changed, fixed}: - - -``` - -For more info on the syntax, check out the [semantic versioning docs](https://www.semver.org) and [keep a changelog](https://www.keepachangelog.com). - -Write your changelog info into the empty file called `changelog_entry.yaml`. When you open your PR, this will automatically be added to the overall changelog. - -## Opening a Pull Request - -Now you've finished your contribution! Please open a pull request (PR) from your branch to the live `master` branch and request review. At times, it may take some time for the team to review your PR, especially for larger contributions, so please be patient--we will be sure to get to it. - -In the first line of your PR, please make sure to include the following: - -``` -Fixes {issue_number} -``` - -This makes it much easier for us to maintain and prune our issue board. - -Please try to be detailed in your PRs about the changes you made and why you made them.
