Version 1.4.4 has been released and is now appearing in the iTunes App Store.  Version 1.4.4 is primarily a stability release to correct a number of issues that arose during the compatibility changes made for the iPhone OS 3.0.  There are also performance enhancements particularly noticeable in improved scrolling speed of the search results.

The next update, Version 1.5, will include additional features and, finally, also new vocabulary – verbs!  The total vocabulary set will increase by about 25%.
