+5550. [func] Print a warning when falling back to the "increment" SOA
+ serial method. [GL #2058]

5549. [protocol] Serve ipv4only.arpa when dns64 is configured. [GL #385]
5548. [placeholder]
- ``ipv4only.arpa`` is now served when ``dns64`` is configured. [GL #385]
+- When using the ``unixtime`` or ``date`` method to update the SOA
+ serial number, ``named`` and ``dnssec-signzone`` silently fell back to
+ the ``increment`` method to prevent the new serial number from being
+ smaller than the old serial number (using serial number arithmetics).
+ ``dnsssec-signzone`` now prints a warning message, and ``named`` logs
+ a warning, when such a fallback happens. [GL #2058]
