Minor Changes

• #​15356 fe265f8 Thanks @​rubuy-74! - Add support for configuring a per-workflow max concurrency limit via workflows[].concurrency.limit in your Wrangler config.

  The limit is the maximum number of Workflow instances that can run concurrently. It is validated as a positive integer and persisted on deploy; the ceiling is enforced server-side. Concurrency is ignored in local development.

  {
    "workflows": [
      {
        "binding": "MY_WORKFLOW",
        "name": "my-workflow",
        "class_name": "MyWorkflow",
        "concurrency": { "limit": 10 }
      }
    ]
  }

Patch Changes

• #​15367 412c79e Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  @​cloudflare/workers-types	^5.20260825.1	^5.20260826.1
  workerd	1.20260825.1	1.20260826.1

• #​15375 92874f6 Thanks @​WillTaylorDev! - Upload wrangler preview modules as multipart form data

  wrangler preview used to base64 the bundle, its modules, and any sourcemaps into a single JSON request body. Base64 inflates content by a third, so a Worker with a large sourcemap could exceed the API request size limit and fail to deploy.

  The preview deployment request is now multipart/form-data. The deployment settings travel in a metadata part and each module follows as its own part carrying raw bytes, matching how wrangler deploy already uploads a Worker.
