I updated all my devices to iDialog 2.0.2 - from my point I did not see any instabilities that needed to be fixed and the description of features is exactly the same as it was before. So it seems nothing big is going on.
However - a timely update like this just a week after the mayor release and added functionality in 2.0 just means Modality Systems takes this App serious and sees some future in the market. Good for them - and good for us (the users).
John Lamb from Modality Systems tweeted me this morning letting me know that the 2.0.2 Update fixed issues with non western keyboards as well as a minor corner-case bug.
Since then it seems the next update 2.0.4 already arrived - this one mentioning fixes for IM sessions and japanese keyboards - nothing mayor but nice to see the updates coming.
