* The RuntimeDirectory= setting now understands unit
specifiers like %i or %f.
- * networkd gained support for setting the IPv6 Router
- Advertisment settings via IPv6AcceptRouterAdvertisements= in
- .network files.
+ * networkd gained support for:
+ - setting the IPv6 Router Advertisment settings via

+ - configuring the HelloTimeSec, MaxAgeSec and
+ ForwardDelaySec bridge parameters in .netdev files.
+ - configuring PreferredSource for static routes in

* udev will now create /dev/disk/by-path links for ATA devices
on kernels where that is supported.
