 * Support for priority inherited mutexes in pthread condition variables on
   non-x86 architectures.
 
+* Port to Xilinx MicroBlaze contributed by David Holsgrove.
+
+* Optimized string functions for AArch64.  Implemented by Marcus Shawcroft.
+
+* Optimized string functions for ARM.  Implemented by Will Newton and
+  Richard Henderson.
+
+* Optimized libm functions for SPARC.  Implemented by David S. Miller.
+
+* Support for building more of ARM glibc as Thumb-2 code.  Implemented by
+  Richard Henderson.
+
+* Support for building most of MIPS glibc as MIPS16 code.  Implemented by
+  Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
+
 * Added a benchmark framework to track performance of functions in glibc.
 
 * New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
   It is based on draft TS 18661 and currently enabled as a GNU extension.
+
+* On Linux, the clock function now uses the clock_gettime system call
+  for improved precision, rather than old times system call.
+
+* Added new API functions pthread_getattr_default_np and
+  pthread_setattr_default_np to get and set the default pthread
+  attributes of a process.
+
+* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
+  This may improve lock scaling of existing programs on TSX capable systems.
+  When the --enable-lock-elision=yes parameter is specified at configure
+  time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
+  mutexes.
