We are going to make a patch release, ParaView 5.6.1, in the next couple of days prior to starting the 5.7 release candidate cycle.
The impetus behind 5.6.1 is a bug in the merge blocks filter that comes up often in LANL’s in situ work flows. (https://gitlab.kitware.com/paraview/paraview/issues/18991)
I am gathering up a merge request for this and a handful of other critical/easy bug fixes in gitlab.
(https://gitlab.kitware.com/paraview/paraview/merge_requests/3267). If you have other fixup that you need to see in this release, please let us know.
