General development activities by Bitcoin Unlimited members do not need a BUIP. For those unfamiliar with the articles, the BU Lead Developer has broad powers to move development forward. BUIPs have 2 purposes; 1. to ensure that a feature will be incorporated into BU before spending the time to develop it, and 2. to block an initiative by the Lead Developer a member disagrees with. However, in general the Lead Developer seeks permission from the membership via BUIP for any major change (i.e. hard fork) so the membership does not need to resort to 2.
This is a list of interesting technical activities undertaken by BU developers but have not become BUIPs.
