* 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.

sockets created by the service may be bound to. This is implemented
via BPF.
* A new ConditionFirmware= condition type has been added to unit files.
It may be used to detect certain firmware features. At the moment it
may check whether running on an UEFI system, a device.tree system, or
if the system is compatible with some specified device-tree feature.
* A new ConditionFirmware= setting has been added to unit files to
conditionalize on certain firmware features. At the moment it may
check whether running on an UEFI system, a device.tree system, or if
the system is compatible with some specified device-tree feature.
* A new ConditionOSRelease= setting has been added to unit files to
check os-release(5) fields. The "=", "!=", "<", "<=", ">=", ">"
operators may be used to check if some field has some specific value
or do a aphanumerical comparison. Equality comparisons are useful for
fields like ID, but relative comparisons for fields like VERSION_ID
or IMAGE_VERSION.
* hostnamed gained a new Describe() D-Bus method that returns a JSON
serialization of the host data it exposes. This is exposed via
