+[2.4][] - 2015-12-04
+--------------------
+
+Bug fix release.
+
+### Changes
+
+* Add support for status/show service by `name:id`
+* Enforce terse mode after boot, if verbose mode is disabled
+* Reenable verbose mode at reboot, if disabled at boot
+* Update section mentioning BusyBox getty
+* Update debugging documentation
+* Allow debug to override terse mode
+* Revert confusing change in service state introduced in [v2.3][].
+  As of v2.4 services are listed as "halted" and "stopped", when
+  they have been halted due to a runlevel changed or stopped by
+  the user, respectively.
+
+### Fixes
+
+* Fix system freeze at reconfiguration.  Changed services that
+  all support `SIGHUP` caused a freeze due to Finit waiting for
+  them to stop.
+* Make sure to start and/or `SIGHUP` services after reconfiguration
+  when there was no services to stop.
