Hi, Version 2.21 has been released. http://www.rakkarsoft.com/raknet/downloads/RakNet.zip 1. Fixed a bug with the autopatcher sending the full file even when compressed. 2. Added the concept of client update ownership to the Distributed Network Object system. 3. Changed chat example to use separate client and servers. 4. Added the string compressor class, so you can write compressed strings to bitstreams. 5. Total rewrite of the master server. The old one is in Master Server / old if you want it.
