 # Release History
 
-## 7.5.0-beta.1 (Unreleased)
+## 7.5.0 (2022-02-08)
 
 ### Features Added
 
 - Add `state` property to `ServiceBusReceivedMessage`. Its value is one of `"active"`, `"deferred"`, or `"scheduled"`. [PR #18938](https://github.com/Azure/azure-sdk-for-js/pull/18938)
 - Add optional boolean `skipParsingBodyAsJson` property to `ServiceBusReceiverOptions` and `ServiceBusSessionReceiverOptions`. By default, the client attempts to parse message body as JSON object, and this new parameter controls whether the client should skip performing this parsing. [PR #18692](https://github.com/Azure/azure-sdk-for-js/pull/18692)
 
-### Breaking Changes
-
 ### Bugs Fixed
 
 - The `processError` callback to `subscribe()` was previously called only for errors on setting up the receiver, errors on message settlement or message lock renewal and not for errors on AMQP link or session. This is now fixed. [PR #19189](https://github.com/Azure/azure-sdk-for-js/pull/19189)
