If you’re using Windows 10 Mobile on the Windows Insider Release Preview ring, you’re wanting to get the newest bits before they’re sent out to non-Insiders. As we reported yesterday, Microsoft has been testing a new build for just this ring, dubbed 10586.218, and today they started rolling it out.

There’s no official changelog, but we did have some inside scoop:

WinBeta can confirm that this new cumulative update fixes a bug on Mobile that involved the apps list not dimming the background when opening and closing apps, making it difficult to read text sometimes. There are likely more bug fixes included in this cumulative patch, so when it arrives keep an eye out on any other fixes.

Update: An official changelog was just posted, and here are the noted changes, fixes and additions:

  • Reliability, performance and stability improvements.
  • Support for Visual Voicemail on Dual SIM phones.
  • Improvements for Bluetooth connectivity, including the reliability of connecting to and staying connected with Bluetooth devices.
  • Fix for a problem that caused audio playback to get occasionally interrupted in Groove Music and other music apps when phone display was turned off.
  • Improvements for Microsoft Edge browser, including support for configuring a prompt before a file download occurs, support for background downloads, and a fix for a problem where opening a link from an another app wouldn’t load the web page.
  • Reliability improvements for Cortana reading text messages aloud and usability improvements for Quiet Hours feature.
  • Improvements for Store reliability, including a fix for a problem that prevented some apps from being updated and installed.
  • Fix for a problem that occasionally caused some apps to show blank tiles after upgrading from Windows Phone 8.1.
    Improvements for PC connectivity via USB on some phones that were upgraded from Windows Phone 8.1.
If you’re one of these special kinds of Windows Insiders, then go to Settings > Update & Security > Phone Update, and get that update downloading. Let us know in the comments if you find anything new.

Update: Reports of Windows 10 Mobile build 10586.218 showing up on non-Insider enabled devices (aka retail sold with Windows 10 Mobile onboard) are sprouting up across the web. Seems as though the new build is an update that is available for all non-Insider devices as well as though put on the Release Preview Ring which acts as a refined and finalized release of Windows 10 Mobile updates and features.
