Minor Changes

• #13326 4a9ba90 Thanks @mattzcarey! - Add Artifacts binding support to wrangler

  You can now configure Artifacts bindings in your wrangler configuration:

  // wrangler.jsonc
  {
    "artifacts": [{ "binding": "MY_ARTIFACTS", "namespace": "default" }]
  }

  Type generation produces the correct Artifacts type reference from the workerd type definitions:

  interface Env {
    MY_ARTIFACTS: Artifacts;
  }

• #13567 d8c895a Thanks @gpanders! - Rename the documented containers SSH config option to ssh

  Wrangler now accepts and documents containers.ssh in config files while continuing to accept containers.wrangler_ssh as an undocumented backwards-compatible alias. Wrangler still sends and reads wrangler_ssh when talking to the containers API.

• #13571 7dc0433 Thanks @must108! - Add regional and jurisdictional placement constraints for Containers. Users can now set constraints.regions and constraints.jurisdiction in wrangler config to control where containers run.

• #12600 50bf819 Thanks @penalosa! - Use workerd's debug port to power cross-process service bindings, Durable Objects, and tail workers via the dev registry. This enables Durable Object RPC via the dev registry, and is an overall stability improvement.

Patch Changes

• #13160 05f4443 Thanks @JoaquinGimenez1! - Log a helpful error message when AI binding requests fail with a 403 authentication error

  Previously, when the AI proxy token expired during a long session, users received an unhelpful 403 error. Now, wrangler detects error code 1031 and suggests running wrangler login to refresh the token.

• #13515 b35617b Thanks @petebacondarwin! - fix: ensure esbuild context is disposed during teardown

  The esbuild bundler cleanup function could race with the initial build. If BundlerController.teardown() ran before the initial build() completed, the stopWatching closure variable would still be undefined, so the esbuild context was never disposed. This left the esbuild child process running, keeping the Node.js event loop alive and causing processes to hang instead of exiting cleanly.

  The cleanup function now awaits the build promise before calling stopWatching, ensuring the esbuild context is always properly disposed.

• #13470 4fda685 Thanks @penalosa! - fix: prevent remote binding sessions from expiring during long-running dev sessions

  Preview tokens for remote bindings expire after one hour. Previously, the first request after expiry would fail before a refresh was triggered. This change proactively refreshes the token at 50 minutes so no request ever sees an expired session.

  The reactive recovery path is also improved: error code: 1031 responses (returned by bindings such as Workers AI when their session times out) now correctly trigger a refresh, where previously only Invalid Workers Preview configuration HTML responses did.

  Auth credentials are now resolved lazily when a remote proxy session starts rather than at bundle-complete time. This means that if your OAuth access token has been refreshed since wrangler dev started, the new token is used rather than the one captured at startup.

• #12456 59eec63 Thanks @venkatnikhilm! - Improve validation and error messaging for R2 CORS configuration files to catch AWS S3-style formatting mistake.

• #13444 cc1413a Thanks @naile! - fix: Pass force query parameter to API in pages deployment delete

• #11918 d0a9d1c Thanks @ksawaneh! - Allow wrangler r2 bucket list to run without a valid Wrangler config

  This is an account-level command and does not require parsing wrangler.toml/wrangler.jsonc. Previously, an invalid local config could prevent listing buckets, making it harder to fix the config.

• #13516 4eb1da9 Thanks @jonnyparris! - Rename "Browser Rendering" to "Browser Run" in all user-facing strings, error messages, and CLI output.

• #13575 6d887db Thanks @lambrospetrou! - Add D1 export prompt message for unavailability, use --skip-confirmation to not show the prompt.

• #13473 5716d69 Thanks @MattieTK! - Update am-i-vibing to v0.1.1 for improved agentic environment detection
