Dear Maintainer,
after the update of PyTables to v3.9.2 we observe a test failure in
Pandas 1.5.3
that prevents the migration of PyTables to testing.
It is just one single test failing. Please find below the relevant part
of the test loh:

The probles seems more related to an issue in the test code rather then
a real bug in PyTables or Pandas.
Indeed the SW correctly report both the main compressor type, "blosc2"
and also the specific compression
filter by blosc2, "blosclz" in this case.
kind regards
