miniflare@4.20260417.0

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;
  }

• #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

• #13515 b35617b Thanks @petebacondarwin! - fix: close all open handles on dispose to prevent process hangs

  Several resources were not being properly cleaned up during Miniflare.dispose(), which could leave the Node.js event loop alive and cause processes (particularly tests using node --test) to hang instead of exiting cleanly:

  • The internal undici Pool used to dispatch fetch requests to the workerd runtime was not closed. Lingering TCP sockets from this pool could keep the event loop alive indefinitely.
  • WebSocketServer instances for live reload and WebSocket proxying were never closed, leaving connected clients' sockets open.
  • The InspectorProxy was not closing its runtime WebSocket connection, relying on process death to break the connection.
  • HyperdriveProxyController.dispose() had a missing return in a .map() callback, causing Promise.allSettled to resolve immediately without waiting for net.Server instances to close.
  • ProxyClientBridge was not clearing its finalization batch setTimeout during disposal.
  • InspectorProxyController.dispose() was not calling server.closeAllConnections() before server.close(), so active HTTP keep-alive or WebSocket connections could prevent the close callback from firing.

• #13557 8ca78bb Thanks @dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  workerd	1.20260415.1	1.20260416.2

• #13579 b6e1351 Thanks @dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  workerd	1.20260416.2	1.20260417.1

• #12913 7f50300 Thanks @Sigmabrogz! - fix(miniflare): use 127.0.0.1 for internal loopback when localhost is configured

  When localhost is configured as the host, Node.js may bind to [::1] (IPv6) while workerd resolves localhost to 127.0.0.1 (IPv4) first. This mismatch causes connection refused errors and 100% CPU spins.

  This fix ensures the internal loopback communication between Node.js and workerd always uses 127.0.0.1 when localhost is configured, while preserving the user-facing URL as localhost.

• #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.

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

• #13557 8ca78bb Thanks @dependabot! - Rename Flags type to Flagship to match the upstream rename in @cloudflare/workers-types

  The Flags type was renamed to Flagship in @cloudflare/workers-types. This updates the import and the return type of getFlagshipBinding accordingly.

• #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.

• #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.

• #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.
