I’m currently trying to set up GitHub Actions CI for my (still dev) package.
However, my package depends on the current master branch of another package (the last release is breaking compatibility).
I could not figure out how to specify that a certain branch is used for the CI.
Is it possible to request this in the Project.toml? I also tried using a Manifest.toml (since it is possible to specify a certain git-tree-sha1 there) but it seemed this has not been used at all.
