As promised, Microsoft has released its official Remote Desktop app for Android and iOS to coincide with the launch of Windows 8.1.

Instagram announced new versions of its app on Android and iOS are now available. The Android 4.2 update adds the intelligent photo straightening tool that iOS users have been enjoying for a few months now.

The iOS 4.2.1 update doesn’t contain any major new features, although Instragam did add new settings that let you mute the playback of video with your ringer switch, or leave it always on. You can also choose to preload videos over Wi-Fi only or leave it always on as well. Unfortunately, there’s still no slo-mo support.

The free updates are available for free in the App Store and Google Play.
