The process of [creating a patch release](https://docs.julialang.org/en/v1/devdocs/build/distributing/#Point-releasing-101) is roughly as follows:

1. Create a new branch (e.g. `backports-release-1.6`) against the relevant minor release
branch (e.g. `release-1.6`). Usually a corresponding pull request is created as well.
1. Create a new branch (e.g. `backports-release-1.10`) against the relevant minor release
branch (e.g. `release-1.10`). Usually a corresponding pull request is created as well.

2. Add commits, nominally from `master` (hence "backports"), to that branch.
