The `release-1.13` branch on the Julia repository now contains the set of commits we’re planning to tag as v1.13.1. The list of commits included since v1.13.0 is available [here](https://github.com/JuliaLang/julia/compare/v1.13.0...release-1.13). As a patch release, it should be non-breaking for existing code and introduce no new features, just bug fixes and performance enhancements.

We encourage users, especially package authors, to test their code using the `1.13-nightly` channel in `juliaup`. If you encounter any issues, please report them on Julia’s [GitHub issue tracker](https://github.com/JuliaLang/julia/issues). If you use GitHub Actions for CI, you can use the `1.13-nightly` version specifier to test the upcoming release.

Assuming all is well, we’ll release v1.13.1 in a couple of days.
