| # This workflow will sync changes in the release candidate branch to master during a | |

| # there exists a release candidate branch corresponding to the current package version | |
| # as declared in pennylane/_version.py, that is if the branch "v0.23.0-rc0" exists while | |
| # the package version is "v0.24.0-dev". | |
