Julia 1.6.3 testing period

The release-1.6 branch on the Julia repository now contains the set of commits we’re planning to tag as v1.6.3, the third patch release in the 1.6 series. The list of commits included since v1.6.2 is available here. As a patch release, it should be strictly non-breaking for existing code and should introduce no new features at all, just bug fixes and performance enhancements.

We encourage users, especially package authors, to test their code using a source build of the release-1.6 branch to ensure there are no changes in behavior. (Binaries are not available for prereleases of patch versions at this time.) A package evaluation run showed no regressions from v1.6.2, so we should be good, but extra testing and assurance is always worthwhile. If you run into any issues, please report them on Julia’s GitHub issue tracker. We ask that you post them there rather than in this thread for visibility to the developers.

Assuming all is well, we’ll move forward with releasing v1.6.3 in a few days.


Hi JuliaLang,

I hope IJulia will be successfully installed in 1.6.3.
I have one more question, why is Juliapro not available?


JuliaPro is being discontinued. See here:

Thanks for quick response.

Is the installation of IJulia fixed in 1.6.3, which does not work in 1.6.2 unless very rigorous IT troubleshooting?

I’m not an IT person, I have 1.6.2 and IJulia works. If you have problems, I suggest asking for help in the forum, specifically mention how you installed it and what errors you are getting.


Are you doing the pkg> build IJulia thing? That is the only requirement within the same Julia environment (i.e., v1.6) as far as IJulia is concerned. If IJulia was working well with v1.6.1, it should work after upgrading Julia to v.1.6.2 and build IJulia.
