The official Podcasts app from Microsoft has been updated on the Windows Phone Store. The latest release brings the app up to version 1.2.15156.0, and is believed to include the usual bug fixes and minor improvements.
Since the version increment is small, and there's no changelog attached to the store listing, we'll assume it's a relatively minor update. Do you use the app? If so, and you happen to notice anything new in the latest release, be sure to shout out in the comments.
