The released beta 3 of EAC is probably the first really stable 1.0 version, as many more bugs are fixed. For an exact list, please read the News.rtf file, which is stored in the EAC directory by the installer (and which can be accessed via the start menu).
This version includes the CTDB plugin written by Gregory Chudov. It will not be installed by default, you need to check the plugin option in the installer. If everything works as expected, the next version of EAC will come with the CTDB plugin installed by default. So try it out now!
