*** Changes since GDB 9
+* Help and apropos commands will now show the documentation of a
+ command only once, even if that command has one or more aliases.
+ These commands now show the command name, then all of its aliases,
+ and finally the description of the command.
+
+* 'help aliases' now shows only the user defined aliases. GDB predefined
+ aliases are shown together with their aliased command.
+
* GDB now supports debuginfod, an HTTP server for distributing ELF/DWARF
debugging information as well as source code.
