v1.20.5 - DoS protections, Performance & More

Dear Extraordinary Survivalists 
v1.20.5, a stable release, can now be downloaded through the account manager.

This update should iron out a lot of oddities, strange behavior, lost items, some exploits, an item dupe bug and lots more, so we highly recommend to update to this version. There is a possibility that one of the latest fixes broke another system but we will then quickly release a fix for that.

Please note, this version is network incompatible with v1.20.4. In other words, with v1.20.5 you can no longer join a v1.20.4 server.

Game updates since 1.20.4

• Feature: Multiplayer server improvements
  • Performance: Slightly better ticks-per-second on large multiplayer servers (Technical info: Improved handling of client packets queue)
  • Protection against one type of denial-of-service attacks (Technical info: Disallow large packets from unauthenticated clients)
  • Two more protections against repeated attempts, disabled by default: server configs TemporaryIpBlockList and LoginFloodProtection. If activated these automatically ban IP addresses when they send invalid packets or when they attempt to connect too many times - more than what a normal user would be able to do. Added command /ipban to list/clear the banned IPs list.  The banned IPs list is temporary, it will automatically be cleared if the server is restarted or after a certain amount of time has passed.
  • Please note: These protections only mitigate certain denial-of-service attacks, not all. Additional protection layers are necessary for solid protection, such as the use of iptables against SYN/PSH-ACK floods and/or use of a reverse proxy.
• Tweak: First person chiseling animation now less view covering
• Tweak: Smoother transitions between sky colors around midnight
