+    description: |-
+      You can now call `create()` without any arguments when using the [Workers API](/workflows/build/workers-api/#create) for Workflows. Workflows will automatically generate the ID of the Workflow on your behalf.
+
+      This addresses a bug that caused calls to `create()` to fail when provided with no arguments.

+      Local development with `wrangler dev` now correctly supports multiple Workflow definitions per script.
