List bugfixes in whatsnew
We decided to start listing user-visible changes to stable versions (that's mostly bugfixes) starting with 1.4.
However, for now, 1.4.0's whatsnew file still contains a link to a diff between 1.4.0
and latest-1.4
. That's not a problem, though, because there are no fixes yet.
The RELEASE-file should be also updated accordingly.
