+# Highlights
+
+## Slot Auto-Tuning (Preview)
+
+Added `WorkerTuner` - this wraps the previously added `SlotSupplier` classes to bring worker tuning options together under one class passed to the WorkerOptions
+    * Added `ResourceBasedTuner` and `ResourceBasedSlotSupplier` - these classes can be used to tune the workers slot count based on available memory and cpu resources. 
+    Set a memory/cpu target and the worker will automatically try to reach those target usage levels.
+    * Added `CompositeTuner` - this allows you to combine different kinds of `SlotSuppliers` to implement `WorkerTuner`.
+
+Please give the resource based tuning a try and let us know how it works for you (feedback on community slack is welcome)! 
+The easiest thing to do is instantiate and pass a `ResourceBasedTuner` to `WorkerOptions`. 
+It'll work best if the worker is the only thing on your host using significant resources. 
+Try setting the thresholds to a reasonable value like 0.8, and make sure that your `JVM -Xmx` value is set appropriately.
+
+Note: Custom Slot Supplier is currently considered experimental and not intended for production use.
+
+## Breaking Changes
+
+### Workflow Update (Preview)
+
+This release includes some breaking changes to the Workflow Update client API.
+
+* `temporal.client.UpdateOptions.setWaitPolicy` has been changed to `temporal.client.UpdateOptions.setWaitForStage`
+* `WaitForStage` is now a required option in `temporal.client.UpdateOptions` and no longer defaults to `Accepted`
+* `io.temporal.client.WorkflowStub.startUpdate` now requires a `WorkflowUpdateStage`.
+* `io.temporal.client.WorkflowStub.startUpdate` now respects the `WorkflowUpdateStage`.
+    *  Previously `startUpdate` may have returned a handle before the desired `WaitForStage` was reached.
+
+### SpringBoot Integration (Preview)
+
+As part of preparation for Spring Boot Integration GA we have renamed our Spring Boot packages to remove the alpha tag:
+    * `temporal-spring-boot-starter-alpha` -> `temporal-spring-boot-starter`
+    * `temporal-spring-boot-autoconfigure-alpha` -> `temporal-spring-boot-autoconfigure`
+
+Users should update their package names when upgrading the Java SDK. 
+
+Stay tuned for future news about SpringBoot integration GA.
