+title: Removed `pallet::getter` usage from Beefy and MMR pallets
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      This PR removes `pallet::getter` usage from `pallet-beefy`, `pallet-beefy-mmr` and `pallet-mmr`, and updates dependant code and runtimes accordingly.
+      The syntax `StorageItem::<T, I>::get()` should be used instead.
