1. Create a release branch off master in the format `release_YYMMDD`, for example `release_230410` for a release in 10 April 2023. Run `git checkout -b release_YYMMDD`
1. Create a tag on that branch in the format `release_YYMMDD_nn` where `nn` is a sequence number (so we can release a patch off the same branch later and they sort correctly). Run `git tag release_YYMMDD_nn`
1. Create a tag in the format `release_YYMMDD_nn` where `nn` is incremented from the previous tag on that branch. For example, if the last tag was `release_230410_02`, create a tag `release_230410_03` for the new patch.
