 ## [Unreleased]
 
-- Move dispatchers from extern block to app argument.
+### Added
+
+- Allow annotating resources to activate special resource locking behaviour.
+  - `#[lock_free]`, there might be several tasks with the same priority accessing
+    the resource without critical section.
+  - `#[task_local]`, there must be only one task, similar to a task local
+    resource, but (optionally) set-up by init. This is similar to move.
