Microsoft has pushed an update to the default Podcasts app for Windows Phone today. Unfortunately, if you were looking for much in the way of what's new or fixed, Microsoft opted not to include a changelog on this one.
In any case, the update bumps Podcasts up to version 1.2.15145.0, and it's available in the store now. The update is most likely just bug fixes and improvements, but be sure to let us know in the comments if you spot anything new and notable.
Thanks for the tips, everyone!
