 Public API changes usually fall into one of the following categories:
 
 * Addition of new methods
+
 * Modifications to prototypes
+
 * Deletion of obsoleted methods
 
 Implementation improvements usually fall into one of the following categories:
 
 * Algorithm improvements in execution time or memory usage
+
 * Critical section reduction
 
 ### API Changes
 
+* The header file <rtems.h> no longer includes <limits.h> and <string.h>.
+
 * Most services use now statically allocated resources and no longer need
   accounting in the application configuration.
+
 * The work area initialization (RTEMS Work Space and C Program Heap) changed.
   BSPs must provide now a `_Memory_Get()` function.
+
 * POSIX timers and signals are now the only POSIX resources which are enabled
   by the POSIX API.
 
 #### API Additions
 
 * Support for recording of high-frequency events in particular on SMP systems
+
 * Support for thread pinning (enables support for Epoch Based Reclamation; used
   by libbsd)
+

+
 * New fatal sources:
+
   * `RTEMS_FATAL_SOURCE_EXCEPTION`
+

-* TBD
+* Priority inheritance is now transitive.
+
+* POSIX key destructors are now called during thread restart.
+
+* More robust thread dispatching on SMP and ARM Cortex-M
 
 #### API Deprecations
 
 * `rtems_iterate_over_all_threads()`.  Use `rtems_task_iterate()` instead.
 
+* `rtems_get_current_processor()`.  Use `rtems_scheduler_get_processor()` instead.
+
+* `rtems_get_processor_count()`.  Use `rtems_scheduler_get_processor_maximum()` instead.

+### SMP Support Improvements
+
+* Reimplemenation of the Multiprocessor Resource Sharing Protocol (MrsP) to

+
+* The default SMP scheduler supports now EDF scheduling, one-to-one and
+  one-to-all thread to processor affinities, and thread pinning.
+
+* Timers (watchdogs) use now per-processor data structures.
+
+* Improved POSIX key to value look up.
+
+* The Ada runtime supports now SMP configurations.
