 *** Changes since GDB 7.12
 
+* 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
+     set $i = 0
+     while $i < $argc
+       eval "print $arg%d", $i
+       set $i = $i + 1
+     end
+   end
+
+* 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.
+
+* New native configurations

+flash-erase
+  Erases all the flash memory regions reported by the target.
+
+* New MI commands
+
+-target-flash-erase
+  Erases all the flash memory regions reported by the target.  This is
+  equivalent to the CLI command flash-erase.
+
+-file-list-shared-libraries
+  List the shared libraries in the program.  This is
+  equivalent to the CLI command "info shared".
+
+* New commands
+
+set disassembler-options
+show disassembler-options
+  Controls the passing of target specific information to the disassembler.
+  If it is necessary to specify more than one disassembler option then
+  multiple options can be placed together into a comma separated list.
+  The default value is the empty string.  Currently, the only supported
+  targets are ARM, PowerPC and S/390.
