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.
