When 2 changes are in the same node, write them one after the other,
and have only one "(Node Name)" thing.

> +* Python Scripting
> +  Access frame registers

This is an incomplete sentence.  I guess you meant something like

  You can now access frame registers from Python scripts.

> +Return the value of @var{register} in this frame. The @var{register}
> +argument must be a string (e.g., 'rsp' or 'r1'), or a register number.
                                    ^^^^^^^^^^^^^
These should be in @code instead of quotes.

> +Returns @code{Gdb.Value} object.
          ^
"a" missing here.

The documentation parts are OK with these fixed.
