76c0ce6Thanks @MattieTK! - Categorise the positional path argument towrangler deployandwrangler versions uploadin command telemetryCommand telemetry now records a coarse category for the entry-point/assets positional (
wrangler deploy <path>) undersanitizedArgs.path, so we can understand whether people pass a file, a directory, or a relational reference such as.or../example. The possible values arefile,directory,current-dir,parent-relative, andnot-found, ornullwhen no positional is provided. The raw path is never sent — only the category.#15597
a83d7acThanks @skepticfx! - Configure application-wide logs for experimental Durable Object-managed ContainersSet
containers[].observability.enabledorcontainers[].observability.logs.enabledwhen usingscheduling_policy: "durable_object". Normal deployments create missing applications and update explicitly configured log settings without a Container rollout. Omitted settings preserve the application configuration; root Worker observability is not inherited for this policy.Version uploads may initialize missing applications but preserve existing settings. Deploying or rolling back Worker versions also preserves existing application settings, and
--containers-rollout=noneskips their updates.#15597
a83d7acThanks @skepticfx! - Support per-image build options for experimental Durable Object-managed ContainersSet
build_contextandbuild_varsalongsidedockerfilein a Container's namedimagesentries. Context paths resolve relative to the Wrangler configuration file and default to the Dockerfile's directory. Build variables are passed as Docker build arguments. Entries using the same Dockerfile with different contexts or variables are built separately.{ "containers": [ { "class_name": "Sandbox", "scheduling_policy": "durable_object", "images": { "app": { "dockerfile": "./docker/Dockerfile", "build_context": ".", "build_vars": { "APP_ENV": "production" } } } } ] }#15638
fa79b26Thanks @G4brym! - Support AI Search bindings in Worker Previewswrangler previewnow acceptsai_searchandai_search_namespacesentries in thepreviewsblock and includes them in Preview deployment bindings. This lets Workers that use AI Search instance or namespace bindings attach existing resources to Preview deployments, including preview-specific instance or namespace names.These bindings are non-inheritable: declare them explicitly under
previews. They attach to existing AI Search resources; preview does not provision new isolated instances or namespaces.#15256
16d1310Thanks @theoephraim! - [private beta]: Add--secrets-fileand--varflags towrangler previewLike
wrangler deployandwrangler versions upload,wrangler previewnow accepts a--secrets-fileflag pointing to a JSON or .env format file, and--var KEY:VALUEpairs that are injected into the Preview deployment as plain text variables. CLI vars override same-named vars from thepreviewssection of your config file, and secrets from the file take precedence over both:wrangler preview --secrets-file .env.preview --var API_URL:https://api.example.com#15453
ca71205Thanks @G4brym! - Remove the gated Web Search binding and Wrangler commandThe unreleased search binding and its experimental command have been removed from Wrangler, Miniflare, and configuration APIs.
#15597
a83d7acThanks @skepticfx! - Allow experimental Durable Object-managed Containers to link by name through exportsContainers using
scheduling_policy: "durable_object"can now specifynameand link fromexports.<Class>.containerwithout repeatingclass_name. Deploy and version upload resolve that link for image preparation, Worker metadata, and Container application creation.Patch Changes
#14775
1be7b97Thanks @dario-piotrowicz! - Sync Local Explorer endpoint lists across agent hintsThe Local Explorer endpoint list is now consistent across the three places it appears: the AGENTS.md template in
create-cloudflare, the runtime agent hint inwrangler dev, and the Vite plugin agent hint. All three now include theobservability/clearendpoint, use the canonical/cdn-cgi/local/explorerpath, and have cross-reference comments pointing to each other.#15409
b149147Thanks @tpmmorris! - Fix per-query overrides forwrangler ai-search search--score-threshold,--max-num-results,--filter, and--rerankingare now sent using the AI Search request schema, so the service applies them to searches instead of ignoring them.#15633
7db596cThanks @dependabot! - Update dependencies of "miniflare", "wrangler"The following dependency versions have been updated:
#14906
a0856daThanks @exKAZUu! - Surface the original error message, name and stack when the dev server reports an internal errorPreviously
wrangler devcould exit with an empty✘ [ERROR]log that gave no indication of what went wrong (e.g.Network connection lost., see #14641). These errors now include their original message, name and stack, so the failure is actually diagnosable.#15179
cb0955fThanks @rioaguspermana! - Treat 502, 503, and 504 as gateway errors during asset upload retriesPages and Workers asset uploads now retry more patiently when the Cloudflare API responds with a 502, 503 or 504 gateway error, reducing concurrency and waiting longer between attempts instead of failing the deploy quickly.
#15399
982b806Thanks @tpmmorris! - Improve over-limitrun_worker_firsterrors when duplicate rules are presentThe error now reports distinct and duplicate-entry counts and lists duplicated rules, making it clear when removing redundant entries can bring the configuration within the limit.
#12369
ffabe74Thanks @43081j! - Replaceexecawithtinyexecfor running subprocesses, shrinking the bundled Wrangler output.#15633
7db596cThanks @dependabot! - Preserve service-worker middleware error propagation with spec-compliant event dispatchWrangler's synthetic service-worker events now propagate listener exceptions to middleware without changing the behavior of user-created
EventTargetinstances.#15400
e03822aThanks @james-elicx! - Reduce the size of Wrangler's published packageExclude test-only, build-only, and obsolete template files from the npm package while retaining all runtime templates.
#15631
c4a6279Thanks @petebacondarwin! - Restore static asset upload concurrency after gateway errorsStatic asset uploads previously remained at concurrency one for the rest of the deployment after any 524 response, which could make large deployments exceed the upload session lifetime. Successful uploads now restore the session's original concurrency gradually while retaining gateway throttling. Requests that were already in flight when throttling began do not restore capacity, so a burst of stale successes cannot immediately undo backpressure.

#15592
945aaa3Thanks @WillTaylorDev! - Add a provisioning delay note when custom domain Preview URLs changeWrangler now explains that DNS and TLS certificate provisioning may continue after a deploy adds a custom domain or enables its Preview URLs. Stable redeploys don't repeat the note.
This assumes that a request which matches the stored custom domain state doesn't restart provisioning. The client infers this from the API changeset and current domain record because this repository can't verify the backend behavior.
#15592
945aaa3Thanks @WillTaylorDev! - Clarify production status labels for custom domain routesWrangler now prefixes explicit custom domain production states with
production:so they match Preview labels. The updated labels appear in deployed trigger output andWRANGLER_OUTPUT_FILE_PATH.#15602
47d906fThanks @dependabot! - Update dependencies of "miniflare", "wrangler"The following dependency versions have been updated:
#15592
945aaa3Thanks @WillTaylorDev! - Avoid replacement prompts for custom domains already on the WorkerWrangler now updates Preview settings without asking to replace a custom domain when that domain already belongs to the deployed Worker. It still asks before replacing domains attached to another Worker.
#15592
945aaa3Thanks @WillTaylorDev! - Explain how to enable Preview URLs when a Preview deployment has nonewrangler previewnow shows URL shapes and configuration snippets for Workers.dev and custom domains. The custom domain snippet preserves every configured route, and the guidance distinguishes missing settings from disabled ones.This changes a private beta feature. The warning also makes clear that

#15480
36aed7fThanks @skepticfx! - Add Durable Object-managed Containers to top-level container configurationWrangler now accepts
scheduling_policy: "durable_object"in the top-levelcontainersarray 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 optionalname, and an optional namedimagesmap. Scheduler-only fields are rejected. Each image provides either a localdockerfileor a digest-pinned managed-registryimage. 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 throughctx.container.imagesandenv.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 localcontainersis 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 omittingcontainersentirely, clears the experimental image binding even withkeep_vars.versions deployvalidates the selected versions before changing traffic and creates their Durable Object-managed applications only after deployment succeeds. Bothdeployandversions deployreport partial completion if application creation fails afterward, with instructions to retry the same command.EXPERIMENTAL_CLOUDFLARE_CONTAINER_IMAGESis a temporary, reserved Wrangler binding until native Container image metadata is available. Its class keys identify managed applications duringversions 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

#15411
0b43395Thanks @xgame92! - Failwrangler versions uploadearly when a Worker has a pending Durable Object migrationWrangler now directs users to run
wrangler deployto apply the migration instead of sending a version upload request that the API will reject.#15518
9d75006Thanks @taylorlee! - Detect named-only module Worker entrypoints correctlyWrangler 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
addEventListenerregistration identifies Service Worker format.#15581
b605aa6Thanks @MattieTK! - Correct Pages-to-Workers delegation analytics for forced and ineligible commandsThe legacy
forcedresult counted every agent-driven Pages command using--force, including commands that could never have been delegated. Wrangler now emitseligible_forcedonly when--forceprevents an otherwise eligible delegation, and records other agent commands asineligiblewith a bounded reason and whether force was used.#15432
f45b596Thanks @razethion! - Prevent delayed internal errors from fetch-only remote bindingsFetch-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.

No runtime change.
#15584
96688b3Thanks @Svector-anu! - Bumpshell-quoteto 1.9.0+ to pick up two disclosed advisoriesshell-quote@1.8.1is affected by a ReDoS inparse()(CVE-2026-13311 / GHSA-395f-4hp3-45gv — an unauthenticated attacker who can feed a string intoparse()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 inquote()(CVE-2026-9277 / GHSA-w7jw-789q-3m8p), both fixed upstream in1.9.0. Wrangler'sparse()wrapper (src/utils/shell-quote.ts) is reachable frompages dev/initcommand-line parsing, so the ReDoS applies; thequote()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
ed5797aThanks @Bortlesboat! - Encode filenames in Pages HTML redirectsFix
wrangler pages devreturning 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
128235aThanks @chinesepowered! - Fixwrangler types --strict-vars=falseemitting invalid TypeScript for an empty array varA var whose value was an empty array produced
()[], which is a syntax error. Because this lands in the generatedworker-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 generatesunknown[].#15494

#14372
dbf6aadThanks @ichernetsky-cf! - Addcontainers[].observabilitysupport towrangler deployWrangler now accepts container-specific observability settings via
containers[].observability, including application-level targeting fields for Containers. Rootobservabilitycontinues to work as a fallback when a container does not define its own observability settings.wrangler deploynow preserves legacyconfiguration.observabilityfor 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
e20df20Thanks @MattieTK! - Delegate agent Pages project creation with a production branch to WorkersWhen 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
e20df20Thanks @MattieTK! - Widen agent Pages-to-Workers delegation to new projects on accounts that already use PagesWhen run by an AI agent,
wrangler pages deployandwrangler pages project createnow 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.

63c7ff1Thanks @tomekancu! - Fixwrangler d1 execute --localbeing extremely slow with large SQL files or commandsThe 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
a4e41dfThanks @NAVEENKUMARKR777! - Fixwrangler devrunning the custom build command twice on startup and on every config changeWrangler already runs the custom
build.commandonce before startingwrangler dev, to resolve the Worker's entry point. Whendev.watchwasn't explicitly disabled,BundlerControllerthen 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 buildvisibly 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-deterministicwasm-optfailures 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.

c0c6504Thanks @for-the-kidz! - Update bundle size warning thresholds to use uncompressed size instead of gzip sizeThe 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
ffc7efdThanks @WillTaylorDev! - Honor Workers Builds name overrides inwrangler previewPreview 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
682cd44Thanks @GregoryCollett! -wrangler devno longer exits when a request to your Worker fails transientlyPreviously, 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 devnow 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.Updated dependencies [
