Minor Changes

• #13151 9c4035b Thanks @G4brym! - Add type generation for AI Search bindings

  Running wrangler types now generates AiSearchNamespace and AiSearchInstance types for ai_search_namespaces and ai_search config bindings respectively. Both simple and per-environment modes are supported.

  // wrangler.json
  {
    "ai_search_namespaces": [
      { "binding": "AI_SEARCH", "namespace": "production" }
    ],
    "ai_search": [
      { "binding": "BLOG_SEARCH", "instance_name": "cloudflare-blog" }
    ]
  }

  // Generated by `wrangler types`
  interface Env {
    AI_SEARCH: AiSearchNamespace;
    BLOG_SEARCH: AiSearchInstance;
  }

• #13011 b9b7e9d Thanks @ruifigueira! - Add experimental headful browser rendering support for local development

  Experimental: This feature may be removed or changed without notice.

  When developing locally with the Browser Rendering API, you can enable headful (visible) mode via the X_BROWSER_HEADFUL environment variable to see the browser while debugging:

  X_BROWSER_HEADFUL=true wrangler dev
  X_BROWSER_HEADFUL=true vite dev

  Note: when using @cloudflare/playwright, two Chrome windows may appear — the initial blank page and the one created by browser.newPage(). This is expected behavior due to how Playwright handles browser contexts via CDP.

• #12992 48d83ca Thanks @RiscadoA! - Add vpc_networks binding support for routing Worker traffic through a Cloudflare Tunnel or network.

  {
    "vpc_networks": [
      // Route through a specific Cloudflare Tunnel
      { "binding": "MY_FIRST_VPC", "tunnel_id": "<tunnel-id>" },
      // Route through the Cloudflare One mesh network
      { "binding": "MY_SECOND_VPC", "network_id": "cf1:network" }
    ]
  }

• #13136 ab44870 Thanks @petebacondarwin! - Display build errors for auxiliary workers in multi-worker mode

  Previously, when running wrangler dev with multiple -c config flags (multi-worker mode), build errors from auxiliary/secondary workers were only logged at debug level, causing Wrangler to silently hang. Build errors from all workers are now displayed at error level so you can see what went wrong and fix it.

• #12992 48d83ca Thanks @RiscadoA! - Fix remote proxy worker not catching errors thrown by bindings during wrangler dev

• #13238 b2f53ea Thanks @guybedford! - Fix source phase imports in bundled and non-bundled Workers

  Wrangler now preserves import source syntax when it runs esbuild, including module format detection and bundled deploy output. This fixes both --no-bundle and bundled deployments for Workers that import WebAssembly using source phase imports.

• #10126 14e72eb Thanks @nekoze1210! - fix: Sort D1 migration files to ensure consistent chronological ordering

  wrangler d1 migrations list and wrangler d1 migrations apply previously returned migration files in an order dependent on the filesystem, which could vary across operating systems. Migration filenames are now sorted alphabetically before being returned, ensuring consistent chronological ordering.

• #13150 4dc94fd Thanks @dario-piotrowicz! - Polish Cloudflare Vite plugin installation during autoconfig

  Projects using Vite 6.0.x were rejected by auto-configuration because the minimum supported version was set to 6.1.0 (the @cloudflare/vite-plugin peer dependency). The minimum version check is now 6.0.0, and when a project has Vite in the [6.0.0, 6.1.0) range, auto-configuration will automatically upgrade it to the latest 6.x before installing @cloudflare/vite-plugin.

• #13051 d5bffde Thanks @dario-piotrowicz! - Use today's date as the default compatibility date

  Previously, when generating a compatibility date for new projects or when no compatibility date was configured, the date was resolved by loading the locally installed workerd package via miniflare. This approach was unreliable in some package manager environments (notably pnpm). The logic now simply uses today's date instead, which is always correct and works reliably across all environments.

• Updated dependencies [5d29055, fb67a18, d5bffde, b9b7e9d, b2f53ea, 48d83ca]:
