I think so.  My point is that the older entry says goto-line has
buffer-local history by default, whereas the newer entry says goto-line
does not have buffer-local history by default.

The older entry came with the following change:

Make goto-line keep a separate input history per buffer

The newer entry came with the following change:

Make goto-line-history buffer local only when so customized

The latter change reverts some parts of the former, and makes the
behaviour customisable, but the older NEWS entry was not updated to
reflect this.  I was hoping you would merge the two NEWS entries or
simply delete the older one, since it no longer accurately represents
the default, and is duplicated by the newer entry.

This part of (info "(elisp) Minibuffer History") also needs updating:

 -- Variable: goto-line-history
     A history list for arguments to ‘goto-line’.  This variable is
     buffer local.

Thanks,
