+    description: |-
+      Workflows is now Generally Available (or "GA").
+
+      This release includes the following new features:
+        * A new `waitForEvent` API that allows a Workflow to wait for an event to occur before continuing execution.
+        * Increased concurrency: you can run up to 4,500 Workflow instances concurrently — and this will continue to grow.
+        * Improved observability, including new CPU time metrics that allow you to better understand which Workflow instances are consuming the most resources and/or contributing to your bill.
+        * Support for vitest for testing Workflows locally and in CI/CD pipelines.
+
+      More information available in the [changelog](/changelog/2025-04-07-workflows-ga/).
