Windows 8.1 was released yesterday, with some changes to the search
interface.
I've pushed out a new version of our Wikipedia app for Windows 8.1 which
uses the new search box style, and fixes a few crashing bugs. The bug fixes
(without the search UI change) are also available as an update on Windows 8.
Both Windows 8 and Windows 8.1 versions are available for installation via
the Windows Store.
Note that source has been broken out from the older cross-platform mobile
app to a standalone repository for future maintenance:
