Both Windows Maps and Shazam are the subject of minor updates pushing out now. Unfortunately, there are no changelogs accompanying either update, so it's tough to tell what's new in each app.
It's likely that both updates simply take care of some nagging bugs and bring performance improvements, which is never a bad thing. As for version numbers, you're looking at 188.8.131.52 for the latest version of Shazam, while Windows Maps comes in at version 4.1601.10150.0. If you happen to notice anything new or notable after updating, be sure to let us know in the comments below.
Update: As pointed out in the comments, Windows Maps now has a settings toggle for the Live Tile option, allowing you to turn the feature on or off as desired.
Thanks for the tips, everyone!
