4.0.0

We've released the next major version of Wrangler — wrangler@4.0.0. Wrangler v4 is a major release focused on updates to underlying systems and dependencies, along with improvements to keep Wrangler commands consistent and clear.

You can run the following command to install it in your projects:

Unlike previous major versions of Wrangler, which were foundational rewrites and rearchitectures — Version 4 of Wrangler includes a much smaller set of changes. If you use Wrangler today, your workflow is very unlikely to change.

A detailed migration guide is available and if you find a bug or hit a roadblock when upgrading to Wrangler v4, open an issue on the cloudflare/workers-sdk repository on GitHub.

Going forward, we'll continue supporting Wrangler v3 with bug fixes and security updates until Q1 2026, and with critical security updates until Q1 2027, at which point it will be out of support.

The full changelog is available at https://github.com/cloudflare/workers-sdk/blob/main/packages/wrangler/CHANGELOG.md#400

2.21.3

Patch Changes

  • #8393 c4653081c Thanks @penalosa! - Deprecate Wrangler v2. Since the release of Wrangler v3 in 2023, we’ve seen great adoption, and today over 95% of active Wrangler usage is with v3.

    As such, Wrangler v2 is now deprecated, and no new features or bug fixes are being published for v2. We strongly recommend you upgrade to the latest version of Wrangler to receive continued support. We have a migration guide to make this process easy! If you encounter any difficulties, please let us know by filing an issue.

3.114.1

Patch Changes

  • #8383 8d6d722 Thanks @matthewdavidrodgers! - Make kv bulk put --local respect base64:true

    The bulk put api has an optional "base64" boolean property for each key. Before storing the key, the value should be decoded from base64.

    For real (remote) kv, this is handled by the rest api. For local kv, it seems the base64 field was ignored, meaning encoded base64 content was stored locally rather than the raw values.

    To fix, we need to decode each value before putting to the local miniflare namespace when base64 is true.

  • #8273 e3efd68 Thanks @penalosa! - Support AI, Vectorize, and Images bindings when using @cloudflare/vite-plugin

  • #8427 a352798 Thanks @vicb! - update unenv-preset dependency to fix bug with Performance global

    Fixes #8407 Fixes #8409 Fixes #8411

  • #8390 53e6323 Thanks @GregBrimble! - Parse and apply metafiles (_headers and _redirects) in wrangler dev for Workers Assets

  • #8392 4d9d9e6 Thanks @jahands! - fix: retry zone and route lookup API calls

    In rare cases, looking up Zone or Route API calls may fail due to transient errors. This change improves the reliability of wrangler deploy when these errors occur.

    Also fixes a rare issue where concurrent API requests may fail without correctly throwing an error which may cause a deployment to incorrectly appear successful.

3.113.0

Minor Changes

  • #8300 bca1fb5 Thanks @vicb! - Use the unenv preset for Cloudflare from @cloudflare/unenv-preset

Patch Changes

  • #8338 2d40989 Thanks @GregBrimble! - feat: Upload _headers and _redirects if present with Workers Assets as part of wrangler deploy and wrangler versions upload.

  • #8288 cf14e17 Thanks @CarmenPopoviciu! - feat: Add assets Proxy Worker skeleton in miniflare

    This commit implements a very basic Proxy Worker skeleton, and wires it in the "pipeline" miniflare creates for assets. This Worker will be incrementally worked on, but for now, the current implementation will forward all incoming requests to the Router Worker, thus leaving the current assets behaviour in local dev, the same.

    This is an experimental feature available under the --x-assets-rpc flag: wrangler dev --x-assets-rpc.

  • #8216 af9a57a Thanks @ns476! - Support Images binding in wrangler types

  • #8304 fbba583 Thanks @jahands! - chore: add concurrency and caching for Zone IDs and Workers routes lookups

    Workers with many routes can result in duplicate Zone lookups during deployments, making deployments unnecessarily slow. This compounded by the lack of concurrency when making these API requests.

    This change deduplicates these requests and adds concurrency to help speed up deployments.
