Windows Phone 8.1 'Blue'

Windows Phone 8.1, codenamed ‘Blue’, is a forthcoming milestone update to the Microsoft Windows Phone operating system. It is expected to be announced at Microsoft’s Build 2014 conference in April, with new hardware arriving in June.

A 'developer preview' program, akin to Update 3, is expected to be announced at Build, with immediate availability for the general public.

All current Windows Phone 8 devices, including the Lumia 520, are expected to receive the update. 

History and Future

Following the re-launch of Windows Phone 8 back in late 2012, the 8.1 update follows on Microsoft’s planned 18-month upgrade path for their mobile operating system. While Windows Phone 8 had three feature-adding updates during its life-cycle (‘Portico’, Update 2, Update 3), the 8.1 update is a significant overhaul of the OS.

After Windows Phone 8.1 is announced (May 2014), it is expected to receive numerous General Distribution Release (GDR) updates, finally being supplanted by a spring 2015 release of ‘Threshold’ aka Windows Phone 8.2 or Windows Phone 9.

On February 11, 2014, the beta SDK for Windows Phone 8.1 leaked. You can follow all of that coverage here:
