feature turned out to be little useful and little used, and
has now been removed from the core and from systemctl.
+ * The dependency types RequiresOverridable= and
+ RequisiteOverridable= have been removed from systemd. They
+ have been used only very sparingly to our knowledge and
+ other options that provide a similar effect (such as
+ systemctl --mode=ignore-dependencies) are much more useful
+ and commonly used. Moreover, they were only half-way
+ implemented as the option to control behaviour regarding
+ these dependencies was never added to systemctl. By removing
+ these dependency types the execution engine becomes a bit
+ simpler. Unit files that use these dependencies should be
+ changed to use the non-Overridable dependency types
+ instead. In fact, when parsing unit files with these
+ options, that's what systemd will automatically convert them
+ too, but it will also warn, asking users to fix the unit
+ files accordingly. Removal of these dependency types should
+ only affect a negligible number of unit files in the wild.
+
+ * Behaviour of networkd's IPForward= option changed
+ (again). It will no longer maintain a per-interface setting,
+ but propagate one way from interfaces where this is enabled
+ to the global kernel setting. The global setting will be
+ enabled when requested by a network that is set up, but
+ never be disabled again. This change was made to make sure
+ IPv4 and IPv6 behaviour regarding packet forwarding is
+ similar (as the Linux IPv6 stack does not support
+ per-interface control of this setting) and to minimize
+ surprises.
+
* In unit files the behaviour of %u, %U, %h, %s has
changed. These specifiers will now unconditionally resolve
to the various user database fields of the user that the
