How to release

This document includes the steps necessary in cutting a new release:

1. Update the version number in pyked/_version.py
2. Create a new h2 header (##) and section in CHANGELOG.md and move the list of Unreleased changes there. (Alternatively, copy and paste the Unreleased section so that it is duplicated. Delete the changes from the top copy and update the version number/date of the bottom copy.) Update the links at the bottom of that file.
3. Bump version in CITATION.md in both citation examples, and add DOI for prior version to list at the bottom.
4. Add new version to chemked-version list in pyked/schemas/chemked_schema.yaml
5. Add and commit the changes to these files:

$ git add CHANGELOG.md CITATION.md pyked/_version.py pyked/schemas/chemked_schema.yaml
$ git commit -m ':gem: Release v#.#.#'

6. Tag the commit, and push:

$ git tag -a v#.#.# -m "v#.#.#"
$ git push upstream --tags

7. On GitHub, create a new release from the tag you just pushed, by going to Releases -> Tags -> Add release notes, and copy the relevant items from CHANGELOG.md
8. ⚡️ You're done! Enjoy your new version of PyKED and the associated DOI that Zenodo just minted for you.
