Thanks for your work.
How could I better follow NIP changes? Just watch the git repo on github? Maybe there could be nostr-nip-report account or hashtag that would scream at devs that there were some changes to existing specs? Some changes are inevitable so I'd rather stay up to date than stay ignorant. 

 Yes, I want to see this too. A list so I can catch up from where I left off. Anything that might be a breaking change should be on the list.
