Release process

How to make a new release of Annif.

1. Check that the master branch is in shape for a new release - tests are passing, no serious open issues etc.
2. Make sure your local master branch is up to date w.r.t. GitHub: git checkout master; git pull
3. Activate the pipenv with pipenv shell if you haven't already
4. Make a new version with bumpversion: bumpversion release
5. Check with git log that the new version number matches your expectations.
6. Push the commit to GitHub: git push
7. Push the version tag too: git push --tags
8. Wait for Travis CI builds to complete. The version tag should trigger a distribution build that is uploaded to PyPI.
9. In GitHub Releases tab, turn the tag into a release and add release notes. This should trigger archiving on Zenodo.
10. Close the milestone corresponding to the release (and create a new one for the next release).
11. Update the wiki documentation to match features of the new release (e.g. new or updated backends) and check that API documentation has been correctly updated (updating should happen on all commits to master).
12. Announce the release on annif-users and other channels (e.g. twitter)
13. Create a blog post (in Finnish) in the Finto wiki about the new release (make sure to include a Label finto)
14. Announce the release on @Fintopalvelu twitter, with a link to the blog post
15. Post the announcement to the mailing lists finto-tiedotus and automaattinen-kuvailu (make sure the message is not held up in moderation)
16. Prepare the master branch for the next development release with bumpversion: bumpversion minor (this should increment the second part of the version number and add a -dev suffix)
17. Check with git log that the new version number matches your expectations.
18. Push the commit to GitHub: git push
19. Push the version tag too: git push --tags
