Minor Changes

• #13023 593c4db Thanks @​jamesopstad! - Add wrangler versions upload support for the experimental secrets configuration property

  When the new secrets property is defined, wrangler versions upload now validates that all secrets declared in secrets.required are configured on the Worker before the upload succeeds. If any required secrets are missing, the upload fails with a clear error listing which secrets need to be set.

  When secrets is not defined, the existing behavior is unchanged.

  // wrangler.jsonc
  {
    "secrets": {
      "required": ["API_KEY", "DB_PASSWORD"]
    }
  }

• #12732 c2e9163 Thanks @​jamesopstad! - Add deploy support for the experimental secrets configuration property

  When the new secrets property is defined, wrangler deploy now validates that all secrets declared in secrets.required are configured on the Worker before the deploy succeeds. If any required secrets are missing, the deploy fails with a clear error listing which secrets need to be set.

  When secrets is not defined, the existing behavior is unchanged.

  // wrangler.jsonc
  {
    "secrets": {
      "required": ["API_KEY", "DB_PASSWORD"]
    }
  }

Patch Changes

• #12896 451dae3 Thanks @​petebacondarwin! - fix: Add retry and timeout protection to remote preview API calls

  Remote preview sessions (wrangler dev --remote) now automatically retry transient 5xx API errors (up to 3 attempts with linear backoff) and enforce a 30-second per-request timeout. Previously, a single hung or failed API response during session creation or worker upload could block the dev session reload indefinitely.

• #12569 379f2a2 Thanks @​MattieTK! - Use qwik add cloudflare-workers instead of qwik add cloudflare-pages for Workers targets

  Both the wrangler autoconfig and C3 Workers template for Qwik were running qwik add cloudflare-pages even when targeting Cloudflare Workers. This caused the wrong adapter directory structure to be scaffolded (adapters/cloudflare-pages/ instead of adapters/cloudflare-workers/), and required post-hoc cleanup of Pages-specific files like _routes.json.

  Qwik now provides a dedicated cloudflare-workers adapter that generates the correct Workers configuration, including wrangler.jsonc with main and assets fields, a public/.assetsignore file, and the correct adapters/cloudflare-workers/vite.config.ts.

  Also adds --skipConfirmation=true to all qwik add invocations so the interactive prompt is skipped in automated contexts.

• #11899 9a1cf29 Thanks @​hoodmane! - Remove cf-requirements support for Python workers. It hasn't worked with the runtime for a while now.

• #11800 875da60 Thanks @​southpolesteve! - Add upgrade hint to unexpected configuration field warnings when an update is available
