title: "`AllowHrmpNotificationsFromRelayChain` barrier for HRMP notifications from the relaychain"

doc:
  - audience: Runtime Dev
    description: |
      A new barrier, `AllowHrmpNotificationsFromRelayChain`, has been added.
      This barrier can be utilized to ensure that HRMP notifications originate solely from the Relay Chain.
      If your runtime relies on these notifications,
      you can include it in the runtime's barrier type for `xcm_executor::Config`.
