* Release checklist

- Check that the current virtualenv matches the current coverage branch.
    $ g ma
    $ make sterile venv install
    $ python -V # should match lowest PYVERSIONS
- start branch for release work
    $ make relbranch
- check version number in coverage/version.py
    - Update to a major/minor version bump if needed.
    - IF PRE-RELEASE:
        - edit to look like one of these:
            version_info = (4, 0, 2, "alpha", 1)
            version_info = (4, 0, 2, "beta", 1)
            version_info = (4, 0, 2, "candidate", 1)
            version_info = (4, 0, 2, "final", 0)
        - also:
            _dev = 0
    - IF NOT PRE-RELEASE:
        $ make release_version
- Update source files with release facts, and get useful snippets:
    $ make edit_for_release cheats
- Edit supported Python version numbers. Search for "PYVERSIONS".
    - Especially README.rst and doc/index.rst
- Look over CHANGES.rst
- Update docs
    - IF PRE-RELEASE:
        - Version of latest stable release in doc/index.rst
    - Make sure the docs are cogged:
        $ make prebuild
    - Don't forget the man page: doc/python-coverage.1.txt
    - Check that the docs build correctly:
        $ tox -e doc
- commit the release-prep changes
    $ make relcommit1
- Generate new sample_html to get the latest, incl footer version number:
    - IF PRE-RELEASE:
        $ make sample_html_beta relcommit2 install
    - IF NOT PRE-RELEASE:
        $ make sample_html relcommit2 install
- Build and publish docs:
    - IF PRE-RELEASE:
        $ make publishbeta
    - ELSE:
        $ make publish
    - commit and publish nedbatchelder.com
- Done with changes to source files
    $ g puo; gshipit
        - check them in on the release prep branch
        - wait for ci to finish
        - merge to main
        - git push
- Start the kits:
    $ opvars github; make build_kits

    - Wait for kits to finish:

        - approve the action using the url printed out
- Tag the tree, update GitHub releases and comment on issues:
    $ make clean tag github_releases comment_on_fixes
- Bump version:
    $ make bump_version
$ deopvars
- Once CI passes, merge the bump-version branch to main and push it
    $ gshipit
- Update readthedocs (this might need to wait 15 minutes after shipping)
    - IF PRE-RELEASE
        - find the latest tag in the inactive list, edit it, make it active.
        - keep just the latest version of each x.y release, make the rest active but hidden.
            - pre-releases should be hidden
    - IF NOT PRE-RELEASE:
        $ opvars; make update_rtd; deopvars
