the 28th June map updates - do they include the WAC updates or not ?
No. Everything except WAC & OpenStreetMap.
Note: There are 3 new VNC's (Deniliquin,Hobart,Launceston) & 2 new TAC's (and 3xTAC's have had a name change). TAC4 is now TAC6, TAC5 is now TAC4 and there's a new TAC5 Broome & Karratha. These maps are hard-coded in, so we'll be releasing an update (v2.7.2.1) on 28th so these new maps are available. Subsequent map name changes/additions will be better handled in v2.8 so this doesn't happen.
I haven't got access to the latest WAC yet (they will update half of Australia). What I'll do is make them
live and any new downloads will include the new ones. I'll put in a facility in v2.8 (testing now) to delete the old WAC to make way for the new.
