         * A new udev hardware database has been added for FireWire devices
           (IEEE 1394).
 
+        * The "net_id" built-in of udev has been updated with three
+          backwards-incompatible changes:
+
+          - PCI hotplug slot names on s390 systems are now parsed as
+            hexadecimal numbers. They were incorrectly parsed as decimal
+            previously, or ignored if the name was not a valid decimal
+            number.
+
+          - PCI onboard indices up to 65535 are allowed. Previously, numbers
+            above 16383 were rejected. This primarily impacts s390 systems,
+            where values up to 65535 are used.
+
+          - Invalid characters in interface names are replaced with "_".
+
+          The new version of the net naming scheme is "v249". The previous
+          scheme can be selected via the "net.naming-scheme=v247" kernel
+          command line parameter.
+
         * sd-bus' sd_bus_is_ready() and sd_bus_is_open() calls now accept a
           NULL bus object, for which they will return false. Or in other words,
           an unallocated bus connection is neither ready nor open.
