The Julia developers are pleased to announce two new releases: v1.5.4, the fourth patch release for Julia 1.5, and v1.6.0-rc2, the second release candidate for Julia 1.6. You can download binaries at [https://julialang.org/downloads](https://julialang.org/downloads) for macOS, FreeBSD (x86-64), Windows (32-, 64-bit), glibc Linux (i686, x86-64, AArch64, PowerPC), and [musl](https://en.wikipedia.org/wiki/Musl) Linux (x86-64).

As a patch release, 1.5.4 contains no new features or breaking changes, only bug fixes, documentation improvements, and performance improvements. You can see the list of commits included since 1.5.3 [here](https://github.com/JuliaLang/julia/compare/v1.5.3...v1.5.4). We recommend anyone currently using 1.5.0, 1.5.1, 1.5.2, 1.5.3 upgrade to 1.5.4.

As a release candidate, 1.6.0-rc2 should **not** be considered production-ready. Rather, it’s intended to give users, especially package developers, a chance to try our their code with 1.6.0 prior to a full release. Check out the [NEWS file](https://github.com/JuliaLang/julia/blob/v1.6.0-rc2/NEWS.md) to see what will be new in 1.6.0.

Note that 1.5 and 1.6 on Travis, [AppVeyor](https://github.com/JuliaCI/Appveyor.jl), and [Cirrus](https://github.com/ararslan/CirrusCI.jl) now refers to 1.5.4 and 1.6.0-rc2, respectively. This will be the case for [GitHub Actions](https://github.com/julia-actions/setup-julia) soon as well.

As always, let us know in the [issue tracker](https://github.com/JuliaLang/julia/issues) if you run into any issues. Please note that any bugs you may encounter should be posted there rather than being discussed in this thread to ensure visibility to the developers.

Enjoy!

Just installed 1.6.0-rc2 on Win10, looks like it should be run with admin rights, filed an issue:

I think “should” is a strong word. You probably don’t want to be running Julia as administrator.

I read this and my thought was “They are already in Julia 1.6.2? How?!” Typos are one of the things that Computer Science can’t solve. 😉

Is this first time in Julia history that there is double release of such kind?

Keep on working on milestone Julia 1.6. 👍

[Nope](https://discourse.julialang.org/t/julia-v1-0-4-and-v1-1-1-have-been-released/24298). It just happens whenever multiple releases are ready to go at the same time. Not as exciting or momentous as it sounds, unfortunately. 😉

I have a theory that Docker images appear after a full workday, like with rc1, so end of Monday would be a good guess, I think?
