Process
-------

- Set release variables::

export VERSION=<version number>
export PREVIOUS=<previous version number>
export ORG="numpy"
export REPO="numpydoc"
export LOG="doc/release/notes.rst"

- Autogenerate release notes::

changelist ${ORG}/${REPO} v${PREVIOUS} main --version ${VERSION} --config pyproject.toml --format rst --out ${VERSION}.rst
changelist ${ORG}/${REPO} v${PREVIOUS} main --version ${VERSION} --config pyproject.toml --out ${VERSION}.md
cat ${VERSION}.rst | cat - ${LOG} > temp && mv temp ${LOG} && rm ${VERSION}.rst

- Update ``__version__`` in ``numpydoc/_version.py``.

- Commit changes::

 git add numpydoc/_version.py ${LOG}
 git commit -m "Designate ${VERSION} release"

- Add the version number (e.g., `v1.2.0`) as a tag in git::

 git tag -s v${VERSION} -m "signed ${VERSION} tag"

If you do not have a gpg key, use -u instead; it is important for
Debian packaging that the tags are annotated

- Push the new meta-data to github::

 git push --tags origin main

where ``origin`` is the name of the ``github.com:numpy/numpydoc`` repository

- Create release from tag::

- go to https://github.com/numpy/numpydoc/releases/new?tag=v${VERSION}
- add v${VERSION} for the `Release title`
- paste contents (or upload) of ${VERSION}.md in the `Describe this release section`
- if pre-release check the box labelled `Set as a pre-release`


- Update https://github.com/numpy/numpydoc/milestones::

- close old milestone
- ensure new milestone exists (perhaps setting due date)

- Update ``__version__`` in ``numpydoc/_version.py``.

- Commit changes::

 git add numpydoc/_version.py
 git commit -m 'Bump version'
 git push origin main
