When the version changes, a new release should be cut. To do this, push a tag with the valid SemVer version number as the tag. It may also be useful to update documentation references at the same time.
For Bookstack version 23.01:
sed -i '' -e 's/22.11.1/23.1.0/g' * # 22.11.1 was the previous version
git commit -am "Update references to version 23.1.0" [-S]
git tag [-s] -a 23.1.0 -m "Release version 23.01"
git push --tags
The workflow will then build, test, push, and release this image.
