Releasing a new version

1. Decide on a new version number. We use semantic versioning.
2. Look through all merged PRs since the last release and write release notes as a list of Features, Bug Fixes,and Other.
3. Once CI has finished and passed on the most recent merge to the default branch, in the github web UI go to "Releases" and tag a new release with the right version number and the release notes you have prepared.
4. Update yul-dc-camerata with the new version of the postgres image and submit a PR.
