cloudflare/workers-sdk wrangler@4.83.0

Minor Changes

• #13391 60565dd Thanks @mikenomitch! - Mark wrangler containers commands as stable

  This changes the status of the Containers CLI from open beta to stable. Wrangler no longer shows [open beta] labels or beta warning text for wrangler containers commands, so the help output matches the feature's current availability.

• #13311 6cbcdeb Thanks @ryanking13! - JS files imported by the Python Workers runtime SDK are now handled as ESM modules.

  This is not a user-facing change, but Python Workers users should update their wrangler version to make sure to get Python workers SDK working properly.

Patch Changes

• #13450 6f63eaa Thanks @petebacondarwin! - Fix POST/PUT requests with non-2xx responses throwing "fetch failed"

  Previously, sending a POST or PUT request that received a non-2xx response (e.g. 401, 400, 403) would throw a TypeError: fetch failed error. This was caused by an undici bug where isTraversableNavigable() incorrectly returned true, causing the 401 credential-retry block to execute in Node.js and fail on stream-backed request bodies. This has been fixed upstream in undici v7.24.8, so we've bumped our dependency and removed the previous pnpm patch workaround.

• #13386 5e5bbc1 Thanks @mksglu! - Make startup network requests non-blocking on slow connections

  Wrangler makes network requests during startup (npm update check, request.cf data fetch) that previously blocked the CLI indefinitely on slow or degraded connections (airplane wifi, trains), causing 10+ second delays.

  • Update check: The banner now races the update check against a 100ms grace period. On a cache hit (most runs) the result resolves in <1ms via the I/O poll phase; on a cache miss the banner prints immediately without blocking. A 3s safety-net timeout caps the update-check library's auth-retry path.
  • request.cf fetch: The fetch to workers.cloudflare.com/cf.json now uses AbortSignal.timeout(3000), falling back to cached/default data on timeout.

• #13469 07a918c Thanks @1000hz! - wrangler preview no longer warns on inheritable binding types being missing from previews config.

• #13463 90aee27 Thanks @roerohan! - Remove unnecessary flagship:read OAuth scope

  The flagship:read scope is not needed since flagship:write already implies read access. This reduces the OAuth permissions requested during login to only what is required.

• Updated dependencies [854d66c, 6f63eaa, aef9825, eaaa728, 58292f6, 5e5bbc1, d5ff5a4, 89c7829]:
