CMSIS Version 5 will focus on improvements and further industry adoption. The license will be changed to the permissive Apache 2.0 license, to enable contributions from interested third parties.
Support for the new ARMv8-M architecture will be added as well as improvements for ARM Cortex-A/Cortex-M based hybrid devices (with a clear focus on Cortex-M interaction).
The CMSIS-RTOS API and RTX reference implementation with get several enhancements:
CMSIS-Pack will get additions for generic example projects, project templates, and multiple download portals. It will also adopt the Flash loader technology from IAR Systems.
As announced on embedded world, the development repository of CMSIS Version 5 is now available on GitHub: https://github.com/ARM-software/CMSIS_5
ARM invites all interested parties to contribute and/or to provide feedback for the CMSIS project using GitHub.

Ok, license changes may be a valid argument. But why 5? There will never be a version 6? CMSIS-Next? CMIS-whatever?
And by the way: I would love to see if CMSIS is going the way Liviu started to go. With c++11 major roadblocks against c++ are gone.
A threadsafe c and c++ lib with threadsafe STL (libstdc++) and maybe some other allocators to choose (because the default allocator of e.g. gcc is not really matching for embedded systems of that size) would be great.
