I think vtk9 is ready at your convenience
for transition 9.5 → 9.6

The library is built and tested in experimental.

I've tested build of those reverse dependencies that build in less
than 30 minutes, and filed bugs against those which fail.  In many
cases build failure was due to a missing #include <iostream> to define
std::cout, not a failure from vtk9.6 itself. Bug#1140923 gdcm is the
most centrally impacting but easily patched.

paraview will be upgraded to 6.1.1 as part of this transition
(also built in experimental)

https://release.debian.org/transitions/html/auto-vtk9.html

Ben file:

title = "vtk9";
is_affected = .depends ~ "libvtk9.5" | .depends ~ "libvtk9.6";
is_good = .depends ~ "libvtk9.6";
is_bad = .depends ~ "libvtk9.5";

This should wait until the python3 transition is finished, unless it somehow
improves things for it.

Cheers,

It does fix python3-vtk9.pydist (mapping python vtk to debian
python3-vtk9), but we've been living with that bug already.
Apart from that it's just general vtk improvements.

It can wait for the other transition.

Control: tags -1 confirmed

Go ahead.

Cheers,
Emilio
