Minor Changes

• #13051 d5bffde Thanks @​dario-piotrowicz! - Deprecate supportedCompatibilityDate export

  The supportedCompatibilityDate export is now deprecated. Instead of relying on the workerd-derived compatibility date, callers should just use today's date directly, e.g. new Date().toISOString().slice(0, 10).

• #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" }
    ]
  }
