cloudflare/workers-sdk wrangler@4.133.0

on GitHub

Minor Changes

• #15600 bac0c6a Thanks @podonnell-dev! - Add placement configuration for Previews

  You can now configure placement in the previews block. Preview-specific placement overrides the top-level placement configuration for Preview Defaults and deployments.

• #15600 bac0c6a Thanks @podonnell-dev! - Improve onboarding guidance for Previews (when previews block is missing from configuration file)

  When a local previews block is absent, Wrangler writes the Preview Base configuration to the local config file. When no Preview Base configuration exists, Wrangler prints a placeholder configuration derived from production bindings and warns against reusing production binding configuration.

Patch Changes

• #15483 71b6f10 Thanks @tpmmorris! - Align Local Explorer Workflow instance status requests with production

  Local Explorer and Wrangler local mode now use the production-compatible status request field for pausing, resuming, restarting, and terminating Workflow instances. Direct Local Explorer API consumers must replace the previous action field with status.

  Successful Local Explorer status updates now return the production-compatible instance status and response timestamp instead of the local-only result.success acknowledgement.

• #15665 ad23e6e Thanks @dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  @cloudflare/workers-types	^5.20260915.1	^5.20260916.1
  workerd	1.20260915.1	1.20260916.1

• #15655 be2437a Thanks @WillTaylorDev! - Send exports with Worker Preview deployments

  wrangler preview dropped the exports block from deployment requests. Durable Objects reached through ctx.exports had no Preview namespace, and cache settings for each entrypoint were lost too.
