With the news that the Minecraft 1.4.5 update will be released next week Tuesday (November 20th, 2012), we've decided to push out a developer quality build (i.e. "it compiles and runs", no guarantees) to help us get to a Beta release faster. As of this post, we've shifted development over to Minecraft 1.4.5 compatibility and now have development builds available with Minecraft 1.4.5 support. While we would love to be able to do this for every Minecraft update, the speed at which we can update is determined by the size and complexity of the update and this varies with each release. Please only use this build if you're familiar with the Minecraft snapshot process and would like to help us get a Beta Build out soon after Minecraft 1.4.5 is officially released. This build is COMPLETELY UNSUPPORTED and if you do not know how to acquire Minecraft 1.4.5 early to use it, you should not be running it. We will be deleting any questions asking how to get this usable. If you have to ask where or how to get the development build, you should NOT be running it and posts of that nature will be deleted. Will plugins break with this build? Provided the developers of the plugins you are using are keeping up with the development of Bukkit, all your plugins should work fine. Unless we specifically have to break plugins or the plugins you are using are employing inappropriate practises, most plugins should work without needing an update whenever we put out a new release. What is a Developer Build? A Developer build is provided AS IS and COMPLETELY UNSUPPORTED. You should only be running these builds if you are completely aware of how to properly make use of them. Support request of ANY KIND will be removed without warning. If you have to ask where or how to get the development build, you should NOT be running it and posts of that nature will be deleted. Known Issues: Torch flame graphical glitch resulting in a torch's flame flickering randomly on the screen. This is a Minecraft bug that can't be fixed by Bukkit. Client displays "Unable to locate sign" debug messages under certain circumstances. This is a Minecraft client change that can't be fixed by Bukkit.
