BIP-132
Committee-based BIP Acceptance Process.
Proposed that committees for developers, miners, merchants and users vote on whether each BIP is accepted.
This was about the BIP process, not Bitcoin's rules. BIP 1 set out how to write a BIP but not how one is accepted. This proposal added fixed periods for comment and opinion, and counted a BIP as accepted with 70% support in three of the four groups.
