release-1.4 branch on the Julia repository now contains the set of commits we’re planning to tag as v1.4.2, the second patch release in the 1.4 series. The list of commits included since v1.4.1 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-1.4 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 v1.4.1, 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.
Assuming all is well, we’ll move forward with releasing v1.4.2 in a few days.
