There's a lot going on in the world of Windows Phone. So much, in fact, that it is sometimes tough to catch every important story.

Device rumors come and go. New apps join the Windows Phone Store, and your favorite app can get a big update with a new look or new features.

Therefore, every week we will compile a list of the Windows Phone news that you just shouldn't miss. Welcome to the "Windows Mobile Weekly Digest."

Windows Mobile

1. Windows Mobile

Microsoft rolled out Windows 10 Mobile build 10586.218 for retail devices, including the AT&T Lumia 950, and members of the Release Preview ring. The update adds several fixes and improvements, but nothing monumental.

Fast ring Insiders picked up Windows 10 Mobile preview build 14322. Most noteworthy in the new build are improvements to Cortana, and a customizable Action Center, which was captured in leaked screenshots earlier in the week.

The FM Radio app is strangely absent from build 14322.

Microsoft quietly confirmed rumors of an upcoming 64-bit version of Windows 10 Mobile. The comment came as part of a feature story about Microsoft Senior Technical Fellow Dave Cutler, who was honored on April 16 as a Computer History Museum Fellow:

"In March 2005, he completed one of his "most gratifying pieces of work" at Microsoft when, partnering with AMD, he helped develop the AMD64 architecture (64-bit extensions to the 32-bit x86 architecture) and led the effort to ship the first two x64 64-bit Windows systems (workstation and server). At the time, some questioned why Microsoft developed a 64-bit system; today most computers are 64-bit systems and even our phones will soon have a 64-bit operating system."

The company may also be working on a flexible phone case that doubles as a second touchscreen. At the moment, the project is just a joint research venture with the University of Applied Sciences Upper Austria, but who know what the future holds?

2. Apps

Viber may be close to releasing their new Windows 10 universal app. The maker of the popular messaging app has begun closed beta testing, so a wide release should only be a hop, skip, and a jump away.

The official Windows Central App picked up an update, bringing article deep-linking to notifications, and some other perks to our fans.

Twitter client Tweet It! got bumped to version 2.7, complete with a brand new Windows 10 Mobile UI. To celebrate, the app is currently on sale for just $1.49.

With the latest update for Windows 10 Insiders, Microsoft's Groove music app has gone truly universal. The PC and Mobile versions are finally aligned at 3.6.1886.0 and share all of the same features.

And Fast ring Insiders also saw their MSN and Office Mobile apps get updated. While details are scarce, the sheer breadth of the update is likely to help prep the operating system for the upcoming Anniversary Update.

3. Games



Rayman Fiesta Run has been re-released in the Store as a universal app for Windows 10 PC and Mobile. Despite the update, there doesn't seem to be much else new with the game.

King's Candy Crush Jelly Saga and Soda Saga both pick up new levels for Windows 10 PC and Mobile. Jelly Saga gets a new episode entitled "Toffee Tops!" while Soda Saga adds 20 new levels in its new "Bubblegum Blueshift!" episode.

Minecraft creator Mojang announced that it will be bringing Realms support to Minecraft Pocket Edition and Windows 10 versions. Realms allows players to play with friends across platforms:

"Minecraft Realms is the easiest way to play Minecraft together with your friends and family. Realms worlds are always online and can only be accessed by an approved group of people. Though it's nice to have some alone time, there's something really special about creating and adventuring as a group. Realms makes that really easy to do."
