Before, the former would print "<optimized out>", and the latter

** Frame filters and frame decorators have been added.
** Temporary breakpoints are now supported.
** Line tables representation has been added.

+ ** New attribute 'name' for gdb.Type objects.
* New targets
Specifies whether Unix child processes are started via a shell or
directly.

* You can now use a literal value 'unlimited' for options that
interpret 0 or -1 as meaning "unlimited". E.g., "set
trace-buffer-size unlimited" is now an alias for "set
