The BitTorrent Community Forum coordinates the development of the BitTorrent protocol suite and its reference implementation. It is the wish of Bram Cohen that the BitTorrent mainline python implementation remain open source and that the protocol development process be modelled after the Python Enhancement Proposal (PEP) process [1].

This document indexes all BitTorrent Enhancement Proposals (BEPs). When a new proposal is submitted, one of the editors assigns a BEP number and updates this index appropriately. Each document has a number that never changes and the history of the document is maintained in git [2].

Accepted BEPs

These BEPs describe mechanisms that have been deployed in one or more BitTorrent implementations and have proven useful. They may require minor revisions. They await the blessing of the BDFL before they can be considered Final.
