-[4.9][UNRELEASED]
+[4.12][] - 2025-04-28
+---------------------
+
+### Changes
+ - Improve notify:s6 readiness compatibility, by Aaron Andersen
+ - Update `runparts` usage text
+
+### Fixes
+ - Fix variable overloading in urandom plugin
+ - Fix buffer overwrite in urandom plugin, reported by Aaron Andersen
+
+
+[4.11][] - 2025-03-27
+---------------------
+
+### Changes
+ - Update documentation regarding transition from runlevel S to 2, how
+   run/tasks must "complete" before Finit can move to the next runlevel
+ - Improve argument handling in bundled getty when launching login
+
+### Fixes
+ - Fix #432: allow services in `setup` state to be stopped.  This fixes
+   a serious blocker introduced in 4.10 that prevented systems from
+   being rebooted when any service was in this state
+ - Fix fallback `SIGKILL` when stopping a service with `SIGTERM` does
+   not work.  This fixes a serious issue with services not responding to
+   the default `SIGTERM`
+ - Fix pre/post/ready/cleanup script execution if service has an
+   optional `env:file` (leading `-`)
+ - Fix blocked signals for pre/post/ready/cleanup scripts preventing
+   normal shutdown when a service/sysv is stopped in its setup state
+ - Fix issue where a pre:script creates a PID file in `/run` cause the
+   service to move from setup state to running.  Any `svc_t` in setup,
+   teardown, or cleanup state should be ignored in the pidfile plugin
+
+
+[4.10][] - 2025-03-03
+---------------------
+
+### 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 #429: regression in v4.9 causing Finit to segfault at shutdown
+ - 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
+ - RFC3154 conformance formatting fix for `/dev/kmsg` fallback logging
