The first release candidate for Julia v1.4.0 is now available. You can get binaries at https://julialang.org/downloads for Linux (i686, x86-64, ARMv7, AArch64), macOS, FreeBSD (x86-64), and Windows (32-, 64-bit). Check out the NEWS file to see what will be new in 1.4.0.
As a release candidate, this should not be considered production-ready. Rather, it’s intended to give users a chance to try out their code with 1.4.0 prior to a full release. Note that 1.4 on Travis, AppVeyor (with Appveyor.jl), and Cirrus (with CirrusCI.jl) now points to 1.4.0-rc1.
Let us know in the issue tracker if you run into any issues. (Note that any bugs you may encounter should be posted there rather than being discussed in this thread for developer visibility.) Assuming no problems arise with this release candidate, we’ll move forward with a full 1.4.0 release soon.
