BTW... Can anyone see any more changes to the zones on that map? And
have anyone found a new version of the "London Connections" map with the
zones of all railway stations within Greater London?


No. Seems a faintly odd change, doesn't it? If you look at a map it
seems very strange that Chigwell should be in zone 4, yet places like
Chingford, Becontree and Chadwell Heath should still be zone 5.

Is it because of some action by Epping Forest DC? The loop also got services
after 8pm on weekdays recently, I wonder if they had any hand in it?

It could also just be a "simplification" so it doesn't matter which way
round the loop you go, the fare will be the same.

Chigwell and Becontree are similar distances from Charing Cross (about 12
miles), so it does seem unfair that Becontree is in zone 5 (especially given
it is in Greater London, while Chigwell is just outside).
