+# **Highlights**
+
+## Task Queue Fairness (Pre-release)
+
+This release adds support for Task Queue Fairness. Fairness is a new feature of Temporal’s task queues that allows for more control over the order that tasks are dispatched from a backlog. It’s intended to address common situations like multi-tenant applications and reserved capacity bands. For more details see the javadoc's on `io.temporal.common.Priority`.
+
+Fairness is currently not supported in any OSS Temporal release, but support will be coming soon. To experiment with this feature please see the [pre-release development server](https://github.com/temporalio/cli/releases/tag/v1.4.1-cloud-v1-29-0-139-2.0) or if you are a Temporal Cloud customer reach out to your SA to be enabled once it is available in Temporal Cloud.

+# Bugfixes
+
+## No longer retry "gRPC message size to large" error
+
+The SDK will no longer retry "gRPC message size to large" errors or related errors. These errors occur if the user tries to make a gRPC request that exceeds the Temporal Service limits (typically 4 MB).
