Protocol Version	New Features
1	Protocol version control
2	Instant win zone and limited usability of brakes
3	Chat control( silencing and kick voting )
4	Fixed the rip bug, clients sent game time of cycle commands
5	new cycle sync code: server sends more data to identify which client command was last executed. Shaped arenas and non-rectangular turns added.
6	Client support for server formatted chat messages.
7	Doublebind countermeasures. Proper cycle speed and acceleration handling and syncing.
8	Server bugfix: turns that were accepted from the client, but not yet executed, are not claimed to be executed in sync messages.
10	New server controlled voting items to add voting items that only require code on the server (code was broken and is no longer used).
11	No actual change, just the bump to 0.2.8.
12	Again, no actual change to be found. Z-Man wonders why.
13	Spectators can now be visible and chat, clients no longer send redundant brake commands.
14	Clientside lag compensation and server controlled ping charity, fullscreen messages.
15	Player authentication, new fixed version of the server controlled vote items.
16	Bugfix: clients no longer get confused if they have to move a cycle backwards during a sync from the server.
17
18-19	Reserved for future usage in legacy versions
20	Zones with more shapes than circles introduced in 0.3.1
21	Network core switched to protobuf messages

Note: Some protocol versions were only available in CVS/SVN/BZR, so not every protocol version corresponds to a Armagetron Experimental version. Likewise, not every version had a network protocol change.
