Minecraft release v1.1 was pushed to clients today, but be aware that if you update you won't be able to connect to the BRD Minecraft server. There are technical reasons for this tied to our use of CraftBukkit for various mods (administrative, multi-world, etc.). Please hold off on updating your clients; optionally, create a backup of your current [tt]minecraft.jar[/tt] prior to updating. [tt]minecraft.jar[/tt] can be found under [tt]C:\Users\%username%\AppData\Roaming\.minecraft\bin[/tt] for Windows Vista, 7 (also accessible from the run menu with [tt]%appdata%\.minecraft[/tt]); [tt]~/.minecraft/bin[/tt] for Linux; or [tt]~/Library/Application Support/minecraft/bin[/tt] for Mac OS X.
Due to bugs in the latest release candidate for CraftBukkit, I will probably be upgrading to the latest development build as soon as v1.1 support is released. This post will be updated when the update becomes available.
