I think the following new features should be brought to a broader attention.

• Mouselook can now be allowed or prohibited by the game host. See the more multiplayer options menu.
• If the game host doesn't use D2X-XL, mouselook gets disabled.
• D2X-XL v1.5.122 now contains a ban feature. Press F8 and type ban:<player name> or ban:#<player number> to ban a player. Names of banned players are stored in the Descent 2 main or data folder in an ascii (index) file named 'banlist.txt'. You can edit it manually. The ban feature does not hinder people to change their name and rejoin, but it makes it somewhat more tedious and saves the game host some work.
• You can now make D2X-XL blend colored weapon light with ambient light. That will look more natural, but the weapon light will be less visible in bright environments.
