Here at WinBeta, our preferred choice of RSS reader is Nextgen Reader, which makes use of Feedly, and is probably one of the best Feedly apps for Windows, as well as Windows Phone. Recently, the app was bumped to version 6.1.918.0, which isn't a very big update, but comes with a few unspecified design improvements.
Additionally, the new update features several bug fixes and performance tweaks to improve the overall usability of the app. The developer didn't introduce any new feature, but who doesn't love bug fixes? They are always welcomed since it can make the app perform seamlessly.
If you happen to be a regular user of Feedly, or looking for a decent RSS app, head over to the Windows Phone Store and grab it.
