Julia v1.7.0-rc1 is now available

The Julia developers are pleased to announce that the first release candidate for Julia v1.7.0 is now available. You can download binaries at https://julialang.org/downloads in the “upcoming release” section for macOS (x86-64, AArch64), FreeBSD (x86-64), Windows (32-, 64-bit), glibc Linux (i686, x86-64, ARMv7, AArch64, PowerPC), and musl Linux (x86-64). Check out the NEWS file to see what will be new in 1.7.0.

As a release candidate, this should not be considered production-ready. Rather, it’s intended to give users, especially package developers, a chance to try our their code with 1.7.0 prior to a full release. Note that 1.7 on Travis, AppVeyor, Cirrus, and GitHub Actions now refers to 1.7.0-rc1.

Let us know in the issue tracker 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.


IIRC it’ll take somewhere around an hour before 1.7 is available on GitHub Actions. Just a heads up to those itching to start testing it out in their CI.

Sorry about that! The website should now be up to date. You may need to refresh the page and/or clear cookies if RC1 still doesn’t show up for you.


I’m finding that Github Actions CI is not recognizing 1.7 as a version, see: Limit maxdim in default contract by emstoudenmire · Pull Request #744 · ITensor/ITensors.jl · GitHub

Is there something I’m missing?

There’s no 1.7 yet, so I guess “1.7.0-rc1” needs to be put instead?

You should do '~1.7.0-0'.



I wish that could just be 1.7. Any complication like that means fewer people testing the prerelease.


I think your proposal in Proposal for simplifying testing of pre-releases · Issue #84 · julia-actions/setup-julia · GitHub (or something similar) is going to be the best way forward here.

Thanks everyone, using ^1.7.0-0 seems to work.

I was initially confused by this line in the original post:

which seems to imply that we could just use '1.7', so maybe the original post should be updated with more specific instructions.

Agreed it would be nice to have '1.7' “just work”.
