Yes, my apologies for that.  However, it should be easy to re-enter pool information if you use one of the default pools as your login information will be pre-populated from previous keychain entries regardless of Asteroid version.  Actually you just gave me an idea, perhaps I can allow custom pools to be saved in a similar manner...  Anyway, Asteroid does include code to migrate preferences from version to version, but the format changed slightly between the two most recent versions and I think there's likely a bug or two in there too.  I'll have a look for 0.9.6, and thanks for the feedback
