+title: Use frame umbrella crate in pallet-babe and pallet-staking-reward-curve
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      Extends the FRAME umbrella crate and uses it in pallet-babe and pallet-staking-reward-curve.
+      Reverse compatible addition to the pallet-staking-reward-curve proc macro to allow for the use of the FRAME umbrella crate.
+      Migrates benchmarking from v1 to v2 for pallet-babe.
