A new CraftBukkit build (#670) is now available that fixes a CRITICAL exploit that allows people to easily take down your server. Please note: plugin names are now set based on the "name:" field in the plugin.yml, not the jar name anymore. This change MAY BREAK SOME PLUGINS. However, it should be easy to address.
