Julia version 1.13.0-alpha2, the first alpha pre-release in the upcoming 1.13 series of releases, is now available. Check out the NEWS.md file to see what will be new in 1.13. Binaries are available via JuliaUp and in the upcoming release section of https://julialang.org/manual-downloads/ for macOS (Intel and M-series processors), Windows (x86 and x86-64), glibc Linux (x86, x86-64, AArch64), and FreeBSD (x86-64).
As an alpha version, 1.13.0-alpha2 should not be considered production-ready. Rather, it’s intended to give users, especially package developers, a chance to try out their code with 1.13.0 prior to a full release.
Note that 1.13 on Cirrus, Travis, and AppVeyor now refers to 1.13.0-alpha2. On GitHub Actions, use ~1.13.0-0 or similar (see the setup-julia action’s README for options).
In case you’re wondering why the first pre-release for 1.13.0 is alpha2 rather than alpha1, that’s because Julia is moving to 2-based indexing in 1.13. (Not actually—there is a 1.13.0-alpha1 git tag, we just opted not to make a full pre-release from it.)
