Editing Unofficial Protocol Extensions

The following is a collection of Hotline protocol extensions discovered or documented in various third party Hotline clients, servers, and trackers. Please note that some of these may clash with other extensions described here, should you wish to implement them. Some are documented, but unused, however.

This page is an active work in progress and is incomplete.

=Hotline Open Protocol Extensions (HOPE)=
