I have been doing this, but perhaps sometimes changes are made to the
Therion Book relating to an existing unchanged feature - explaining default
font sizes instance? I always check the new versions, as I have many unasked
questions, which are too low a priority to bother the forum with.

Comparing text in documents is a bit tedious to do on a regular basis, if
the authoring software can do it quickly and easily.  Perhaps it does not,
and if so that is OK.
