 *** Changes since GDB 7.12
 
-* GDB and GDBserver now require building with a C++11 compiler.
+* GDB now supports access to the PKU register on GNU/Linux. The register is
+  added by the Memory Protection Keys for Userspace feature which will be
+  available in future Intel CPUs.
+
+* GDB now supports C++11 rvalue references.
+
+* Python Scripting
+
+  ** New functions to start, stop and access a running btrace recording.
+  ** Rvalue references are now supported in gdb.Type.
+
+* GDB now supports recording and replaying rdrand and rdseed Intel 64
+  instructions.
+
+* Building GDB and GDBserver now requires a C++11 compiler.
 
   For example, GCC 4.8 or later.

 * Support for Java programs compiled with gcj has been removed.
 
+* User commands now accept an unlimited number of arguments.
+  Previously, only up to 10 was accepted.
+
+* The "eval" command now expands user-defined command arguments.
+
+  This makes it easier to process a variable number of arguments:

+   define mycommand

+
+* Target descriptions can now describe registers for sparc32 and sparc64.
+
+* GDB now supports DWARF version 5 (debug information format).
+  Its .debug_names index is not yet supported.

+  Controls the passing of target specific information to the disassembler.
+  If it is necessary to specify more than one disassembler option then
