One useful change not mentioned yet (in this thread at least, though
we've certainly been here before!) is the Upper Holloway to Archway/
Northern line (non-)interchange.

What is the best term for describing such an interchange - an out-of-
station interchange might be a good one, but in ticketing terminology
that means a journey where a change that involves transfer between
stations on the street can be completed on a single ticket. Using the
phrase 'out-of-station interchange' where through tickets might not be
valid would perhaps just serve to confuse things.

Since PAYG was extended to the Overground there are 3 new valid out of
station interchanges for PAYG purposes. These are

West Hampstead LU / West Hampstead NLL / West Hampstead Thameslink

Was validity extended to WHT on 11 November? Is there now a gate line?

Yes, on the 11th November. There is no gate line, just validators by
the exit to the main road. I first found out about it in the week
starting 11th November, but it was clearly advertised on the website
and at the station.

Validity used to stop at Kentish Town.
http://www.tfl.gov.uk/tickets/oysteronline/5823.aspx supports your
point.

shows the old validity.
