Some minor widget enhancements - now you can force that the phonetics are never displayed in the widget. Also, if you reinstall the app or reboot your device, the old word is still shown
Improved swipe left/right, up/down on Word Details screen - there was a bug introduced in 2.5.3 where (at least on Xperia X10) swiping left/right or up/down no longer worked. That has been fixed and the swiping generally improved - now you can swipe from anywhere on the screen (before you could not swipe starting from a clickable item like the Hanzi or Search/Links icons). Also, the swipe distance and speed thresholds have been lowered to make swiping more comfortable - no more frenetic swiping necessary!
Fixed bug regarding list items not in dictionary. This bug appeared in 2.5.0-2.5.3. For example, bringing up the hsk6 list would show the same entry (報酬, 报仇,“bao4 chou5”) multiple times due to a caching bug. It was this entry because this was the first entry in hsk6 that does not appear in the dictionary (CC-CEDICT 2.1.1). All later list items not in the dictionary were showing as the “bao4 chou5” also. However, clicking on them would bring the correct item up in the Word Details screen (so at least that worked). Side note: CC-CEDICT does have this word but with a different tone on the second syllable.
