 *** 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.
+
+* Python Scripting
+
+  ** New functions to start, stop and access a running btrace recording.
+
+* 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.
+
+  It is no longer possible to build GDB or GDBserver with a C
+  compiler.  The --disable-build-with-cxx configure option has been
+  removed.
+
+* Building GDB and GDBserver now requires GNU make >= 3.81.
+
+  It is no longer supported to build GDB or GDBserver with another
+  implementation of the make program or an earlier version of GNU make.
+
+* Native debugging on MS-Windows supports command-line redirection
+
+  Command-line arguments used for starting programs on MS-Windows can
+  now include redirection symbols supported by native Windows shells,
+  such as '<', '>', '>>', '2>&1', etc.  This affects GDB commands such
+  as "run", "start", and "set args", as well as the corresponding MI
+  features.
+
+* Support for thread names on MS-Windows.
+
+  GDB now catches and handles the special exception that programs
+  running on MS-Windows use to assign names to threads in the
+  debugger.
+
+* 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

+-target-flash-erase
+  Erases all the flash memory regions reported by the target.  This is
+  equivalent to the CLI command flash-erase.
