New Release 19.4.21¶
This is a hot-fix release 1, it includes only the solution to a single bug that was released in 19.4.20 (#2793).
Said bug doesn’t seem to be present on 20.0.18 and that’s why you’ll not find the matching hot-fix release for our v20 branch.
Upgrading is highly suggested, but always backup and test before doing it.
