+- Fix: IPv4 prefix length verification when RFC8950 is enabled.
+
+  When a peer is configured for RFC8950 support, the prefix length is checked for the IPv6 limits only. This will permit too long IPv4 (up to /48) prefixes and will reject short IPv4 (< /12) prefixes.
+
+  See also `GitHub issue 130 <https://github.com/pierky/arouteserver/issues/130>`__.
