-* details ...
+* Remove deprecated k_mem_pool_defrag code
+* Add the following application-facing memory domain APIs:
+  * k_mem_domain_init() - to initialize a memory domain
+  * k_mem_domain_destroy() - to destroy a memory domain
+  * k_mem_domain_add_partition() - to add a partition into a domain
+  * k_mem_domain_remove_partition() - to remove a partition from a domain
+  * k_mem_domain_add_thread() - to add a thread into a domain
+  * k_mem_domain_remove_thread() - to remove a thread from a domain
+* add k_calloc() which uses kernel heap to implement traditional calloc()
+  semantics.
+* Introduce object validation mechanism: All system calls made from userspace
+  which involve pointers to kernel objects (including device drivers) will need
+  to have those pointers validated; userspace must never be able to crash the
+  kernel by passing it garbage.

+
+* The implementation for sys_rand32_get() function has been moved to a new
+  "random" subsystem. There are new implementations for this function, one based
+  in the Xoroshift128+ PRNG (using a hardware number generator to seed), and
+  another that obtains random numbers directly from a hardware number generator
+  driver. Hardware number generator drivers have been moved to a
+  "drivers/entropy" directory; these drivers only expose the interface provided
+  by include/entropy.h.
