There haven't been any changes to the font locking code in this
release compared to Emacs 21.3.  So I'd say no.  It would have to be a
CVS snapshot or checkout.  But of course installing and using such a
snapshot is not everybody's cup of tea.

If an alltt environment is not fontified in brown you either forgot to
activate parsing or something else went wrong.  In the latter case you
will probably find some hint in the *Messages* buffer.

It is probably more reliable to check for correct fontification with
the verbatim environment instead of the alltt environment because the
former does not require an additional AUCTeX style file ot be loaded.
In case the verbatim environment is fontified but not the alltt
environment it is likely you forgot to enable parsing as mentioned
above.
