Minor Changes

• #15685 b9f1cdc Thanks @Ankcorn! - Add native support for the Analytics SQL binding

  Declare the zero-configuration binding in wrangler.json with "analytics": { "binding": "ANALYTICS" }. Wrangler uploads the analytics binding type and proxies it to the remote service during local development, so wrangler dev can call the binding without unsafe.bindings.

• #15948 a0712e5 Thanks @akoval-cf! - Add beta K2 producer bindings for existing streams

  Configure a stream created through Wrangler, the Dashboard, or the API in wrangler.json:

  {
    "k2": [
      {
        "binding": "ORDERS",
        "stream": "0123456789abcdef0123456789abcdef"
      }
    ]
  }

  The binding supports env.ORDERS.send([{ content: new TextEncoder().encode("order"), headers: { event: "order.created" } }]). Batches use either all ArrayBuffer or all Uint8Array content. Check the returned success value, handle rejected RPC promises, and retry only when the returned error explicitly allows it. Generated environment types describe this producer contract without requiring a separate application dependency.

  K2 requires an enabled account. Deployment credentials need Worker deployment and K2 configuration-read access. Default Wrangler logins now request the K2 OAuth scopes; existing OAuth users should run wrangler login again to grant the new permissions. Development always uses a real K2 stream and may incur usage charges; no local simulator is provided. The remote setting can be omitted, remote: true suppresses the usage warning, and remote: false is rejected. Consumption is not part of this Worker binding.
