Minor Changes

• #​15480 36aed7f Thanks @​skepticfx! - Add Durable Object-managed Containers to top-level container configuration

  Wrangler now accepts scheduling_policy: "durable_object" in the top-level containers array and creates its namespace-backed application after the Worker upload resolves the Durable Object namespace ID. The namespace ID is also the application ID, so repeated deploys idempotently ensure the same application without name-based lookup, modification, or a Containers rollout.

  Durable Object-managed entries accept class_name, scheduling_policy, an optional name, and an optional named images map. Scheduler-only fields are rejected. Each image provides either a local dockerfile or a digest-pinned managed-registry image. Wrangler builds or resolves each image, waits while Cloudflare prepares it for the Containers runtime, and uploads the resulting references with the Worker version for access through ctx.container.images and env.EXPERIMENTAL_CLOUDFLARE_CONTAINER_IMAGES. Local development support for these entries is deferred to a follow-up.

  Existing scheduler-backed entries and Durable Object migrations continue to work unchanged.

  With --containers-rollout=none, existing Workers retain their deployed Container metadata and image binding even when local containers is omitted or empty; local scheduler edits are also ignored. The upload stops if the deployed versions cannot be recovered. Existing Workers for Platforms dispatch scripts reject this flag before upload because their API does not expose enough metadata to preserve Container associations safely. First deployments can still skip Container preparation and rollout. Without this flag, removing managed Containers, including by omitting containers entirely, clears the experimental image binding even with keep_vars.

  versions deploy validates the selected versions before changing traffic and creates their Durable Object-managed applications only after deployment succeeds. Both deploy and versions deploy report partial completion if application creation fails afterward, with instructions to retry the same command.

  EXPERIMENTAL_CLOUDFLARE_CONTAINER_IMAGES is a temporary, reserved Wrangler binding until native Container image metadata is available. Its class keys identify managed applications during versions deploy, including classes with empty image maps. User configuration cannot declare a binding with this name; existing versions that already use it are treated as Container configuration.

• #​15493 493e635 Thanks @​GregBrimble! - Remove wrangler preview settings commands

  The private-beta wrangler preview settings and wrangler preview settings update commands are no longer available.

Patch Changes

• #​15411 0b43395 Thanks @​xgame92! - Fail wrangler versions upload early when a Worker has a pending Durable Object migration

  Wrangler now directs users to run wrangler deploy to apply the migration instead of sending a version upload request that the API will reject.

• #​15518 9d75006 Thanks @​taylorlee! - Detect named-only module Worker entrypoints correctly

  Wrangler now distinguishes named-only module Workers from legacy Service Workers that happen to have named exports. A default export identifies a module Worker; otherwise, legacy addEventListener registration identifies Service Worker format.

• #​15581 b605aa6 Thanks @​MattieTK! - Correct Pages-to-Workers delegation analytics for forced and ineligible commands

  The legacy forced result counted every agent-driven Pages command using --force, including commands that could never have been delegated. Wrangler now emits eligible_forced only when --force prevents an otherwise eligible delegation, and records other agent commands as ineligible with a bounded reason and whether force was used.

• #​15432 f45b596 Thanks @​razethion! - Prevent delayed internal errors from fetch-only remote bindings

  Fetch-only remote bindings such as D1 and R2 previously opened an unused WebSocket RPC session. RPC sessions are now created only when an RPC method is called.

• #​15585 f69f95a Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  @​cloudflare/workers-types	^5.20260908.1	^5.20260910.1
  workerd	1.20260908.1	1.20260910.1

• #​15554 bff525d Thanks @​XiaoZ-0218! - Add the missing transferred_classes migration to the config schema

  DurableObjectMigration described new_classes, new_sqlite_classes, renamed_classes and deleted_classes, but not transferred_classes. normalizeAndValidateConfig has always validated that key, and the deploy path forwards it to the API along with the rest of the step, so Transfer migrations worked — but config-schema.json is generated from the type, so an editor resolving $schema reported a valid, documented migration as an unknown key.

  Adding the field to the type puts it in the generated schema. No runtime change.

• #​15584 96688b3 Thanks @​Svector-anu! - Bump shell-quote to 1.9.0+ to pick up two disclosed advisories

  shell-quote@1.8.1 is affected by a ReDoS in parse() (CVE-2026-13311 / GHSA-395f-4hp3-45gv — an unauthenticated attacker who can feed a string into parse() can block the event loop for tens of seconds with plain space-separated input, no shell metacharacters required) and by an object-token escaping bug in quote() (CVE-2026-9277 / GHSA-w7jw-789q-3m8p), both fixed upstream in 1.9.0. Wrangler's parse() wrapper (src/utils/shell-quote.ts) is reachable from pages dev/init command-line parsing, so the ReDoS applies; the quote() call site only ever passes string arguments, so the object-token issue was not reachable here, but there is no reason to stay on a vulnerable range once a patch exists.

• #​15563 ed5797a Thanks @​Bortlesboat! - Encode filenames in Pages HTML redirects

  Fix wrangler pages dev returning a 502 response when redirecting HTML paths containing Unicode characters. Keep reserved characters in filenames encoded in the redirect destination and preserve the request query string.

• #​14889 128235a Thanks @​chinesepowered! - Fix wrangler types --strict-vars=false emitting invalid TypeScript for an empty array var

  A var whose value was an empty array produced ()[], which is a syntax error. Because this lands in the generated worker-configuration.d.ts, it did not just break that one line — the whole file failed to parse, so no binding types resolved at all. An empty array now generates unknown[].

• #​15494 f8aea7e Thanks @​GregBrimble! - Use previews_base_config for Preview configuration

  Preview commands now read the Worker Previews Base configuration from the previews_base_config API field.

• #​15569 24ef86b Thanks @​RealBhupesh! - Fix wrangler workflows instances describe crashing on dynamic retry delays

  The Workflows API serializes function retry delays as "[dynamic]". The describe command previously parsed that as a duration, produced an Invalid Date, and threw RangeError: Invalid time value before printing remaining steps. It now renders unknown (dynamic delay) and also tolerates attempts whose end timestamp is missing.

Minor Changes

• #​14372 dbf6aad Thanks @​ichernetsky-cf! - Add containers[].observability support to wrangler deploy

  Wrangler now accepts container-specific observability settings via containers[].observability, including application-level targeting fields for Containers. Root observability continues to work as a fallback when a container does not define its own observability settings.

  wrangler deploy now preserves legacy configuration.observability for existing container apps that still use rollout-based observability, while using top-level application observability for new or already-migrated apps.

  Existing application diffs are now normalized even when stored resource limits cannot be mapped to a named instance type. API-only metadata and equivalent managed-registry image names no longer appear as edits or affect whether deployment changes require a rollout.

• #​15004 e20df20 Thanks @​MattieTK! - Delegate agent Pages project creation with a production branch to Workers

  When run by an AI agent, wrangler pages project create --production-branch <name> is now eligible for delegation to a Workers static-assets deploy. The production branch names the target that a Workers deploy would publish to, so it does not need to disqualify a brand-new project from delegation.

  wrangler pages deploy --branch <name> remains on Pages because an interactive new-project flow separately prompts for its production branch. The deployment branch may therefore represent a preview and cannot safely be converted into a production Workers deployment.

• #​15004 e20df20 Thanks @​MattieTK! - Widen agent Pages-to-Workers delegation to new projects on accounts that already use Pages

  When run by an AI agent, wrangler pages deploy and wrangler pages project create now delegate a brand-new static Pages project to a Workers static-assets deploy even when the account already has other Pages projects. The gate is now per-project rather than per-account: a command targeting a project that already exists stays on Pages, but a new project is delegated regardless of the account's other Pages projects.

  A project name restored from the Pages configuration cache is only used when the cache belongs to the currently authenticated account. An account-matching cached name remains on Pages even when the project is missing remotely, preserving the user's recorded Pages intent. After switching accounts, an otherwise unnamed deploy stays on Pages rather than treating a stale cached project name as a new project on the selected account.

Patch Changes

• #​15560 edb3631 Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  @​cloudflare/workers-types	^5.20260907.1	^5.20260908.1
  workerd	1.20260907.1	1.20260908.1

• #​15557 63c7ff1 Thanks @​tomekancu! - Fix wrangler d1 execute --local being extremely slow with large SQL files or commands

  The local SQL splitter consumed quoted strings and comments character-by-character, re-checking the full accumulated string each time. This made splitting a large quoted value or comment quadratic, so seed files could take tens of seconds to run. The splitter now only inspects a bounded trailing window on each step, making splitting effectively linear. The remote path is unaffected as it imports the file server-side.

• #​15542 a4e41df Thanks @​NAVEENKUMARKR777! - Fix wrangler dev running the custom build command twice on startup and on every config change

  Wrangler already runs the custom build.command once before starting wrangler dev, to resolve the Worker's entry point. When dev.watch wasn't explicitly disabled, BundlerController then unconditionally ran the same build command again the moment it started watching for changes, and repeated this on every subsequent config reload too.

  For fast build commands this just meant duplicate log output (e.g. a vite build visibly running twice at startup). For slower or stateful build commands, running two builds concurrently against the same output files could corrupt the result or fail outright (for example, non-deterministic wasm-opt failures have been reported for Rust builds).

  The initial watcher setup now only bundles the output the build command already produced, instead of re-running the command. Real file changes detected by the watcher still re-run the build command as before.

• #​15323 ea5634e Thanks @​Sakshamm-Goyal! - Prevent Wrangler from exiting when a process capturing its output closes the pipe.

  Wrangler now ignores broken-pipe errors from stdout and stderr while preserving the existing failure behavior for other output errors.

• #​14001 c0c6504 Thanks @​for-the-kidz! - Update bundle size warning thresholds to use uncompressed size instead of gzip size

  The compressed script size limits (3 MiB free / 10 MiB paid) have been removed server-side in favor of a single 64 MiB uncompressed limit. The bundle size reporter now compares the uncompressed bundle size against this 64 MiB limit for its color-coded warnings, instead of comparing gzip size against the old 3 MiB compressed limit.

• #​15499 ffc7efd Thanks @​WillTaylorDev! - Honor Workers Builds name overrides in wrangler preview

  Preview commands now target the Worker name supplied by Workers Builds instead of the name in local Wrangler configuration. This prevents preview builds from failing when the two names differ.

• #​15252 682cd44 Thanks @​GregoryCollett! - wrangler dev no longer exits when a request to your Worker fails transiently

  Previously, a transient network failure on a single request — most commonly a request arriving just as an idle internal connection was closed, after roughly five seconds without traffic — could take down the whole dev server with an empty ✘ [ERROR], leaving the port unbound until restarted. In CI test suites, one such failure caused every remaining test to fail with connection errors.

  wrangler dev now automatically retries the affected request if it is safe to repeat (GET and HEAD requests). If a request still fails, it fails individually — the error is logged with the request method and URL — and the dev server keeps serving.
