 *****************************************************************************

+*** 0.7.0 ***
+- NEW: Memory Pools functionality added, this mechanism allows constant-time
+  allocation/freeing of constant size objects. It can be used to dynamically
+  allocate kernel objects like Semaphores, Mutexes, Threads etc it can also
+  handle application-defined objects. The allocator is, of course, thread-safe.
+- NEW: Kernel-provided sbrk() function, it is used internally by the Memory
+  Pools but can also be used by the C runtime. There is also an option to
+  meke the Memory Pools use an user-provided sbrk() function.
+
 *** 0.6.10 ***
 - FIX: Fixed a case-sensitiveness error in lpc214x_ssp.c, it affected only
  linux/unix users.
