Alpha2 is out. It fixes a bunch of bugs, adds an anti-flood option, and adds a different icon for disabled connections. There's a changelog packaged with the release with more detail in it.
Alpha3 will mostly just include a bunch of bugfixes for the IRC part of the program. The DC part of the program is pretty solid (except for hashing, still no support for ADC password-protected logins).
Please report any bugs you find to me via email or using the project tracker.
