After having written the notes, I realized that the added points contain changes
that were part of the 5.4.2 release. These were never included in any release
notes. I asked on IRC whether they should be added to this file or not, but
didn’t get an answer to this question. If they should not be added here, I can
remove them.

| * Subversion sources of the convert extension now interpret the encoding of | |||||
| URLs like Subversion. Previously, there were situations where the convert | |||||
| extension recognized a repository as present but Subversion did not, and | |||||
| vice versa. | |||||
| * The empty changeset check of in-memory rebases was fixed to match that of | |||||
| normal rebases (and that of the commit command). | |||||
| * The push command now checks the correct set of outgoing changesets for | |||||
| obsolete and unstable changesets. Previously, it could happen that the check | |||||
