Java Edition Alpha server 0.1.1

0.1.1 was an Alpha server version released with client v1.0.16 on August 12, 2010.

Additions

 * Added online authentication for online servers.
 * The server can now be started in either online/secure mode or offline/insecure mode. A secure server requires all connecting players to first authenticate on minecraft.net, then checks that the authentication matches, before letting the player in. A server running in offline mode won’t do any such checks, nor will it ask the client to authenticate, but you can’t be sure that people who connect really are who they claim they are. Offline mode is meant for LAN play where you know the people connecting to the server.

Changes

 * Made the server save terrain more frequently.
