 *** Changes since GDB 9
 
+* Debugging MS-Windows processes now sets $_exitsignal when the
+  inferior is terminated by a signal, instead of setting $_exitcode.
+
+* Multithreaded symbol loading has now been enabled by default on systems
+  that support it (see entry for GDB 9, below), providing faster
+  performance for programs with many symbols.
+
+* New commands
+
+set exec-file-mismatch -- Set exec-file-mismatch handling (ask|warn|off).
+show exec-file-mismatch -- Show exec-file-mismatch handling (ask|warn|off).
+  Set or show the option 'exec-file-mismatch'.  When GDB attaches to
+  a running process and can determine the name of the executable file
+  the process runs, this new option indicates whether to detect mismatch
+  between the name of the current executable file loaded by GDB
+  and the name of the executable file used to start the process.
+  If 'ask', the default, display a warning and ask the user
+  whether to load the process executable file; if 'warn', just display
+  a warning; if 'off', don't attempt to detect a mismatch.

   can turn it on using 'maint set worker-threads unlimited'.
 
+* Multi-target debugging support
+
+  GDB now supports debugging multiple target connections
+  simultaneously.  For example, you can now have each inferior
+  connected to different remote servers running in different machines,
+  or have one inferior debugging a local native process, an inferior
+  debugging a core dump, etc.
+
+  This support is experimental and comes with some limitations -- you
+  can only resume multiple targets simultaneously if all targets
+  support non-stop mode, and all remote stubs or servers must support
+  the same set of remote protocol features exactly.  See also "info
