                What has changed in GDB?

+set|show varsize-limit
+  This new setting allows the user to control the maximum size of Ada

+*** Changes in GDB 8.1
+
+* GDB now supports dynamically creating arbitrary register groups specified
+  in XML target descriptions.  This allows for finer grain grouping of
+  registers on systems with a large amount of registers.

+* The 'ptype' command now accepts a '/o' flag, which prints the
+  offsets and sizes of fields in a struct, like the pahole(1) tool.
 
 * New "--readnever" command line option instructs GDB to not read each
   symbol file's symbolic debug information.  This makes startup faster
