+=== camel-azure-servicebus - Camel-managed message lock renewal
+
+When consuming from Azure Service Bus in `PEEK_LOCK` mode with
`maxAutoLockRenewDuration > 0`, Camel now
+actively renews message locks using a dedicated
`ServiceBusReceiverAsyncClient` and Camel's internal
+`PeriodTaskScheduler`. This addresses a limitation where the Azure SDK's
built-in lock renewal is tied
+to the `processMessage` callback duration, which returns immediately for
asynchronous Camel routes —
+causing long-running exchanges to silently lose their message locks.
+
+The new behavior activates automatically when all of the following are true:
+
+* No custom `processorClient` is provided
+* Receive mode is `PEEK_LOCK`
+* `maxAutoLockRenewDuration > 0`
+* Session mode is disabled
+
+No configuration changes are required. The existing `maxAutoLockRenewDuration`
option controls how long
+Camel will continue renewing a message's lock.
