The big change is in regards to the Music apps, which now grabs the new branding of Groove Music announced earlier this week. Everything from the new Live Tile (which reveals now playing info) to the app itself has the new Groove label on it. No other changes are noted.
The version has been updated for phone and Windows 10 desktop. Look for version 3.6.1154.0 in the Store for the Groove labeled release.
Also, the MSN Weather app for Windows 10 and Windows 10 Mobile has been updated to version 126.96.36.199 and 188.8.131.52 (for Mobile). There appear to be some minor UI tweaks and performance improvements, but the biggest change is the removal of ads within the app. Indeed, many users using the Insider feedback app have complained about ads within Microsoft's first-party apps and it looks like they may be listening. Although we will have to see if this is just a glitch or a change in policy.
If you are using Windows 10 grab the apps and let us know what you think!
