FIX Protocol Extension Packs

The FIX Protocol is updated and extended constantly. Rather than releasing new FIX versions from time to time, the Protocol evolves through Extension Packs, each produced by the Global Technical Committee based on requirements from FIX’s working groups and members, and published immediately. The term “FIX Latest” stands for the most recent version of the Protocol up to and including the latest Extension Pack.
