Release Steps:

• suppose the current tag is 4.2.2 and the next is 4.2.3
• with no staged commits and a clean status...
• meld a summary of git log $(git tag --sort version:refname | tail -n 1)..HEAD --oneline (all commits since last tag) with whatever hash with [4.2.3] in changelog
• commit, push
• mkvirtualenv releasetest
• check that pip install . and python -c "import pyamg; pyamg.test()" pass (outside source directory)
• remove untracked files git clean -xdf
• the following can be done with a pre-release, v4.2.3-alpha.6, for testing. It will not become the default on pypi and gh release create can be marked with --prerelease (below)
• mark fallback_version in pyproject.toml
• commit, push
• git tag -a v4.2.3 -m "version 4.2.3"
• git push
• git push --tags
• then release the version on Github: gh release create v4.2.3 --notes "see changelog.md"
  • This will trigger the GHA .github/workflows/wheels.yml which builds wheels and a source distribution, and publishes to pypi

Testing notes:

• do not use seeds such as 0, 1, 42, 100
• for each needed seed, generate a "random" int
• python3 -c "import numpy as np; np.random.seed(); seeds = np.random.randint(0, 2**32 - 1, 5); print(seeds)"
