Release Notes: Three denial of service attacks (or accidents) have been fixed. Forged clients could crash or freeze a server by sending wrong data that was left unchecked, and a clumsy remote administrator could freeze the server by entering commands that produce too much output. 0.2.8.2.1 fixes all of that.
Release Notes: This release aims mainly at giving players greater control over each other. You can now silence other players and issue polls to kick unfriendly players from the server. The "huge chat" exploit has been disabled by truncating chat messages both on the server and on the clients. Additionally, the long sought-after option to display the player names above the cycles so you can identify them easier has been implemented.
