I usually use
diffchecker to find the changes, but for some reason this time diffchecker flags pretty much the whole document as being different (which it isn't)
So I scanned through the new version and the only change I've spotted is the removal of the
highlighted words below:
4(g) Intermediate surface sectors are permitted at the passenger’s expense.
Transoceanic surface sectors between TC1-TC2 and TC1-TC3 are not permitted.
EXCEPTION: For travel originating in the South West Pacific, one transoceanic surface sector between TC1-TC2 or TC1-TC3 is permitted.
The first crossing between TC areas must be flown, not surfaced.
