How to issue an xarray release in 16 easy steps

Time required: about an hour.

These instructions assume that upstream refers to the main repository:

$ git remote -v
{...}
upstream        https://github.com/pydata/xarray (fetch)
upstream        https://github.com/pydata/xarray (push)

1. Ensure your main branch is synced to upstream:

   git switch main
   git pull upstream main
   

2. Add a list of contributors. First fetch all previous release tags so we can see the version number of the last release was:

   git fetch upstream --tags
   

   This will return a list of all the contributors since the last release:

   git log "$(git tag --sort=v:refname | tail -1).." --format=%aN | sort -u | perl -pe 's/\n/$1, /'
   

   This will return the total number of contributors:

   git log "$(git tag --sort=v:refname | tail -1).." --format=%aN | sort -u | wc -l
   

3. Write a release summary: ~50 words describing the high level features. This will be used in the release emails, tweets, GitHub release notes, etc.
4. Look over whats-new.rst and the docs. Make sure "What's New" is complete (check the date!) and add the release summary at the top. Things to watch out for:
   • Important new features should be highlighted towards the top.
   • Function/method references should include links to the API docs.
   • Sometimes notes get added in the wrong section of whats-new, typically due to a bad merge. Check for these before a release by using git diff, e.g., git diff v{YYYY.MM.X-1} whats-new.rst where {YYYY.MM.X-1} is the previous release.
5. Open a PR with the release summary and whatsnew changes; in particular the release headline should get feedback from the team on what's important to include.
6. After merging, again ensure your main branch is synced to upstream:

   git pull upstream main
