No one knows when bukkit is going to come out creeper, not even the develpers know. Here is what vilSeph (creator of bukkit) says:
With the Minecraft 1.3 release date fast approaching, a lot of people are wondering when we will be releasing a CraftBukkit Recommended Build for Minecraft 1.3. We hope this short announcement will answer those questions.
Due to the size of the impending 1.3 update, we are unable to guarantee that we'll have a compatible CraftBukkit Recommended Build out in time for the release of Minecraft 1.3. Although we started working on the update immediately after the Minecraft 1.3 preview was made available to the public, a lot of things were added, removed and changed in Minecraft from 1.2.5 and, as such, this update requires more work than usual to get things up and running. That being said, we'll continue to do our best to get an update out within a reasonable amount of time and will likely follow our usual policy of promoting the first Recommended Build the moment we get something that compiles and runs without any testing done whatsoever.
As we have done a significant amount of...
Also, for the people who updated here is what else vilSeph said:
If you're using the new Minecraft launcher, you have a choice on whether or not you want to update to the latest Minecraft release - simply choose "Not now" when it asks if you want to update and you can continue to play on your pre-update Minecraft server.
If you're not using the new Minecraft launcher, backup your old launcher and update it by downloading it from
http://minecraft.net, then follow the steps above.
It usually takes us a few hours AT LEAST to get Bukkit working with the latest Minecraft update, so you're better off playing a different game or staying on the previous version of Minecraft, instead. If you have a special server that requires lots of mods, like a class-based server, consider backing up your world, running the new Minecraft update and calling it a grief/fun/fool-around period OR stay on your current version and just keep playing.
Just remember, always backup so you can switch between versions. You're no longer forced to go weeks without a Bukkit powered server.
Once we have a new Bukkit build that is compatible with the newest Minecraft update, we'll put it under rigorous testing and then promote it as a Recommended Build. Usually, due to the way Bukkit and CraftBukkit are designed, plugins should work just fine but there's no guarantee that this is always the case so be sure to test everything on a test server before you go live.
Lastly, we're fully aware that a new update is out - usually before anyone else. Don't spam the forums with threads or IRC with messages informing us that there's a new Minecraft update out. We know. And we're working on updating Bukkit to work with it. The more you bother us, the longer it'll take.
