Sourced from wrangler's releases.

wrangler@4.18.0

Minor Changes

• #9393 34b6174 Thanks @​jamesopstad! - Hard fail on Node.js < 20. Wrangler no longer supports Node.js 18.x as it reached end-of-life on 2025-04-30. See https://github.com/nodejs/release?tab=readme-ov-file#end-of-life-releases.

Patch Changes

• #9308 d3a6eb3 Thanks @​dario-piotrowicz! - expose new utilities and types to aid consumers of the programmatic mixed-mode API

  Specifically the exports have been added:

  • Experimental_MixedModeSession: type representing a mixed-mode session
  • Experimental_ConfigBindingsOptions: type representing config-bindings
  • experimental_pickRemoteBindings: utility for picking only the remote bindings from a record of start-worker bindings.
  • unstable_convertConfigBindingsToStartWorkerBindings: utility for converting config-bindings into start-worker bindings (that can be passed to startMixedModeSession)

• #9347 b8f058c Thanks @​penalosa! - Improve binding display on narrower terminals

• Updated dependencies [d9d937a, e39a45f, fdae3f7]:

  • miniflare@4.20250525.0

wrangler@4.17.0

Minor Changes

• #9321 6c03bde Thanks @​petebacondarwin! - Add support for FedRAMP High compliance region

  Now it is possible to target Wrangler at the FedRAMP High compliance region. There are two ways to signal to Wrangler to run in this mode:

  • set "compliance_region": "fedramp_high" in a Wrangler configuration
  • set CLOUDFLARE_COMPLIANCE_REGION=fedramp_high environment variable when running Wrangler

  If both are provided and the values do not match then Wrangler will exit with an error.

  When in this mode OAuth authentication is not supported. It is necessary to authenticate using a Cloudflare API Token acquired from the Cloudflare FedRAMP High dashboard.

  Most bindings and commands are supported in this mode.

  • Unsupported commands may result in API requests that are not supported - possibly 422 Unprocessable Entity responses.
  • Unsupported bindings may work in local dev, as there is no local validation, but will fail at Worker deployment time.

  Resolves DEVX-1921.

• #9330 34c71ce Thanks @​edmundhung! - Updated internal configuration to use Miniflare’s new defaultPersistRoot instead of per-plugin persist flags

• #8973 cc7fae4 Thanks @​Caio-Nogueira! - Show latest instance by default on workflows instances describe command
