Here's a summary:
Promoted to the Football League: Barrow & Harrogate
Relegated to the National League: Macclesfield (Looks like they are going to be wound up but won't be replaced)
Promoted to the National League: King's Lynn, Altrincham, Weymouth and Wealdstone
Relegated from the National League: Ebbsfleet, Chorley, AFC Fylde
The reason 4 were promoted and 3 were relegated is down to Bury's expulsion from the League. However it will be an odd number of teams again as Macclesfield will be thrown out.
