Hi Paul,

As I mentioned earlier [1], recent updates in core LaTeX and accompanying
changes in the array package broke build of perfbook.

There are two modes of incompatibilities.

  1. arydshln assumes array's internal implementation of a past version of
     array, which is no longer true with array >=v2.6.

  2. A "LaTeX Warning:" message in loading parnotes.sty.

Neither arydshln nor parnotes is actively maintained, so here are
workarounds made in perfbook-lt.tex.

Patch 1/3 adds a rollback option to array and sticks with array v2.5 or
earlier.

Patch 2/3 enables a silence filter for the particular warning.

Patch 3/3 is a follow up change to use date as rollback options of
glossaries related packages.  By saying [=2022-10-01] rather than
[=v2.07], [=v4.49], etc., it becomes obvious when those packages worked
well with our custom code for glossaries & indexing.
