To be precise, there have been substantial changes in (IIRC) 9.5.1
from 9.5.0, so it's actually not between 9.5 and 9.6.  Note that the
XML format is still considered "experimental", and backward
incompatible changes may still happen.  However, we understand such
changes are very inconvenient even if it's still "experimental", and
we'll try to keep future changes in a backward compatible manner as
much as possible.

No, but you can at least check the statistics version to see if it's
compatible for your parser.  The current version is 2.0, and, in
general, changes in the same major version (currently "2") should be
backward compatible.

The latter.  If a statistics counter is provided per-view basis, you
need to sum up the counters of all views to get the total.
