+[4.10][] - 2025-02-23
+---------------------
+
+### Changes
+ - Add support for `cleanup:[0-3600,]script`, runs before service is
+   removed, unlike `post:script` that runs when service is stopped
+ - Improved entropy gathering in tertiary fallback of urandom plugin
+ - Reclassify `sysv` from run/task class to `service`
+
+### Fixes
+ - Fix #427: using an external getty with custom login program cause
+   Finit to use login program as the getty command
+ - Fix #428: allow `sysctl` path to be set at build time
+ - Fix possible memory leak when sourcing a service `env:file`
+ - Finit now waits until all `post:scripts` have run before returning
+   OK to `initctl <reload|runlevel>`.  This also applies to the new
+   `cleanup:scripts` introduced in this release
