 *** Changes since GDB 11
 
+* Configure changes
+
+--enable-threading
+
+  Enable or disable multithreaded symbol loading.  This is enabled
+  by default, but passing --disable-threading or --enable-threading=no
+  to configure will disable it.
+
+  Disabling this can cause a performance penalty when there are a lot of
+  symbols to load, but is useful for debugging purposes.

+set debug linux-nat on|off
+show debug linux-nat
+  These new commands replaced the old 'set debug lin-lwp' and 'show

+maint show gnu-source-highlight enabled
+  Whether GDB should use the GNU Source Highlight library for adding
+  styling to source code.  When off, the library will not be used, even
+  when available.  When GNU Source Highlight isn't used, or can't add
+  styling to a particular source file, then the Python Pygments
+  library will be used instead.
