The first release candidate for Julia v1.2.0 is now available. Binaries can be found at the usual download page https://julialang.org/downloads/. There are source tarballs available as github releases, or of course you can check out and build the release-1.2 branch.
Please test if you can, and file any issues you encounter at https://github.com/JuliaLang/julia/issues. If you maintain any packages, this is a good time to add CI for 1.2, check compatibility, and tag new versions as needed.
Thank you and happy coding!
