[ Subscribe to RSS ](https://developers.cloudflare.com/changelog/rss/index.xml) [ View RSS feeds ](https://developers.cloudflare.com/fundamentals/new-features/available-rss-feeds/) All products ![hero image](https://developers.cloudflare.com/_astro/hero.CVYJHPAd_26AMqX.svg) Feb 06, 2025 1. ### [Request timeouts and retries with AI Gateway](https://developers.cloudflare.com/changelog/post/2025-02-05-aig-request-handling/) [ AI Gateway ](https://developers.cloudflare.com/ai-gateway/) AI Gateway adds additional ways to handle requests - [Request Timeouts](https://developers.cloudflare.com/ai-gateway/configuration/request-handling/#request-timeouts) and [Request Retries](https://developers.cloudflare.com/ai-gateway/configuration/request-handling/#request-retries), making it easier to keep your applications responsive and reliable. Timeouts and retries can be used on both the [Universal Endpoint](https://developers.cloudflare.com/ai-gateway/usage/universal/) or directly to a [supported provider](https://developers.cloudflare.com/ai-gateway/usage/providers/). **Request timeouts**A [request timeout](https://developers.cloudflare.com/ai-gateway/configuration/request-handling/#request-timeouts) allows you to trigger [fallbacks](https://developers.cloudflare.com/ai-gateway/configuration/fallbacks/) or a retry if a provider takes too long to respond. To set a request timeout directly to a provider, add a `cf-aig-request-timeout` header. Provider-specific endpoint example ``` curl https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/workers-ai/@cf/meta/llama-3.1-8b-instruct \ --header 'Authorization: Bearer {cf_api_token}' \ --header 'Content-Type: application/json' \ --header 'cf-aig-request-timeout: 5000' --data '{"prompt": "What is Cloudflare?"}' ``` **Request retries**A [request retry](https://developers.cloudflare.com/ai-gateway/configuration/request-handling/#request-retries) automatically retries failed requests, so you can recover from temporary issues without intervening. To set up request retries directly to a provider, add the following headers: * cf-aig-max-attempts (number) * cf-aig-retry-delay (number) * cf-aig-backoff ("constant" | "linear" | "exponential) Feb 05, 2025 1. ### [AI Gateway adds Cerebras, ElevenLabs, and Cartesia as new providers](https://developers.cloudflare.com/changelog/post/2025-02-04-aig-provider-cartesia-eleven-cerebras/) [ AI Gateway ](https://developers.cloudflare.com/ai-gateway/) [AI Gateway](https://developers.cloudflare.com/ai-gateway/) has added three new providers: [Cartesia](https://developers.cloudflare.com/ai-gateway/usage/providers/cartesia/), [Cerebras](https://developers.cloudflare.com/ai-gateway/usage/providers/cerebras/), and [ElevenLabs](https://developers.cloudflare.com/ai-gateway/usage/providers/elevenlabs/), giving you more even more options for providers you can use through AI Gateway. Here's a brief overview of each: * [Cartesia](https://developers.cloudflare.com/ai-gateway/usage/providers/cartesia/) provides text-to-speech models that produce natural-sounding speech with low latency. * [Cerebras](https://developers.cloudflare.com/ai-gateway/usage/providers/cerebras/) delivers low-latency AI inference to Meta's Llama 3.1 8B and Llama 3.3 70B models. * [ElevenLabs](https://developers.cloudflare.com/ai-gateway/usage/providers/elevenlabs/) offers text-to-speech models with human-like voices in 32 languages. ![Example of Cerebras log in AI Gateway](https://developers.cloudflare.com/_astro/cerebras2.qHYP0ZnF_XMtnx.webp) To get started with AI Gateway, just update the base URL. Here's how you can send a request to [Cerebras](https://developers.cloudflare.com/ai-gateway/usage/providers/cerebras/) using cURL: Example fetch request ``` curl -X POST https://gateway.ai.cloudflare.com/v1/ACCOUNT_TAG/GATEWAY/cerebras/chat/completions \ --header 'content-type: application/json' \ --header 'Authorization: Bearer CEREBRAS_TOKEN' \ --data '{ "model": "llama-3.3-70b", "messages": [ { "role": "user", "content": "What is Cloudflare?" } ]}' ``` Feb 04, 2025 1. ### [Fight CSAM More Easily Than Ever](https://developers.cloudflare.com/changelog/post/2025-02-04-easier-onboarding-for-csam-scanning-tool/) [ Cache / CDN ](https://developers.cloudflare.com/cache/) You can now implement our **child safety tooling**, the **[CSAM Scanning Tool](https://developers.cloudflare.com/cache/reference/csam-scanning/)**, more easily. Instead of requiring external reporting credentials, you only need a verified email address for notifications to onboard. This change makes the tool more accessible to a wider range of customers. **How It Works** When enabled, the tool automatically [hashes images for enabled websites as they enter the Cloudflare cache ↗](https://blog.cloudflare.com/the-csam-scanning-tool/). These hashes are then checked against a database of **known abusive images**. * **Potential match detected?** * The **content URL is blocked**, and * **Cloudflare will notify you** about the found matches via the provided email address. **Updated Service-Specific Terms** We have also made updates to our **[Service-Specific Terms ↗](https://www.cloudflare.com/service-specific-terms-application-services/#csam-scanning-tool-terms)** to reflect these changes. Feb 04, 2025 1. ### [Expanded AI insights in Cloudflare Radar](https://developers.cloudflare.com/changelog/post/2025-02-04-radar-ai-insights/) [ Radar ](https://developers.cloudflare.com/radar/) [**Radar**](https://developers.cloudflare.com/radar/) has expanded its AI insights with new API endpoints for Internet services rankings, robots.txt analysis, and AI inference data. #### Internet services ranking Radar now provides [rankings for Internet services](https://developers.cloudflare.com/radar/glossary/#internet-services-ranking), including Generative AI platforms, based on anonymized 1.1.1.1 resolver data.

Feb 03, 2025 1. ### [Terraform v5 Provider is now generally available](https://developers.cloudflare.com/changelog/post/2025-02-03-terraform-v5-provider/) [ Cloudflare Fundamentals ](https://developers.cloudflare.com/fundamentals/)[ Terraform ](https://developers.cloudflare.com/terraform/) ![Screenshot of Terraform defining a Zone](https://developers.cloudflare.com/_astro/2024-02-03-terraform-v5-screenshot.mW8OaFoS_Z2pw8Bq.webp) Cloudflare's v5 Terraform Provider is now generally available. With this release, Terraform resources are now automatically generated based on OpenAPI Schemas. This change brings alignment across our SDKs, API documentation, and now Terraform Provider. The new provider boosts coverage by increasing support for API properties to 100%, adding 25% more resources, and more than 200 additional data sources. Going forward, this will also reduce the barriers to bringing more resources into Terraform across the broader Cloudflare API. This is a small, but important step to making more of our platform manageable through GitOps, making it easier for you to manage Cloudflare just like you do your other infrastructure. The Cloudflare Terraform Provider v5 is a ground-up rewrite of the provider and introduces breaking changes for some resource types. Please refer to the [upgrade guide ↗](https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/guides/version-5-upgrade) for best practices, or the [blog post on automatically generating Cloudflare's Terraform Provider ↗](https://blog.cloudflare.com/automatically-generating-cloudflares-terraform-provider/) for more information about the approach.

Feb 02, 2025 1. ### [Removed unused meta fields from DNS records](https://developers.cloudflare.com/changelog/post/2025-02-02-removed-meta-fields/) [ DNS ](https://developers.cloudflare.com/dns/) Cloudflare is removing five fields from the `meta` object of DNS records. These fields have been unused for more than a year and are no longer set on new records. This change may take up to four weeks to fully roll out. The affected fields are: * the `auto_added` boolean * the `managed_by_apps` boolean and corresponding `apps_install_id` * the `managed_by_argo_tunnel` boolean and corresponding `argo_tunnel_id` An example record returned from the API would now look like the following: Updated API Response ``` { "result": { "id": "", "zone_id": "", "zone_name": "example.com", "name": "www.example.com", "type": "A", "content": "192.0.2.1", "proxiable": true, "proxied": false, "ttl": 1, "locked": false, "meta": { "auto_added": false, "managed_by_apps": false, "managed_by_argo_tunnel": false, "source": "primary" }, "comment": null, "tags": [], "created_on": "2025-03-17T20:37:05.368097Z", "modified_on": "2025-03-17T20:37:05.368097Z" }, "success": true, "errors": [], "messages": []} ``` For more guidance, refer to [Manage DNS records](https://developers.cloudflare.com/dns/manage-dns-records/). Jan 31, 2025 1. ### [Workers for Platforms now supports Static Assets](https://developers.cloudflare.com/changelog/post/2025-01-31-workers-platforms-static-assets/) [ Workers for Platforms ](https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/) Workers for Platforms customers can now attach static assets (HTML, CSS, JavaScript, images) directly to User Workers, removing the need to host separate infrastructure to serve the assets. This allows your platform to serve entire front-end applications from Cloudflare's global edge, utilizing caching for fast load times, while supporting dynamic logic within the same Worker. Cloudflare automatically scales its infrastructure to handle high traffic volumes, enabling you to focus on building features without managing servers. #### What you can build **Static Sites:** Host and serve HTML, CSS, JavaScript, and media files directly from Cloudflare's network, ensuring fast loading times worldwide. This is ideal for blogs, landing pages, and documentation sites because static assets can be efficiently cached and delivered closer to the user, reducing latency and enhancing the overall user experience. **Full-Stack Applications:** Combine asset hosting with Cloudflare Workers to power dynamic, interactive applications. If you're an e-commerce platform, you can serve your customers' product pages and run inventory checks from within the same Worker. * [ JavaScript ](#tab-panel-4783) * [ TypeScript ](#tab-panel-4784) index.js ``` export default { async fetch(request, env) { const url = new URL(request.url); // Check real-time inventory if (url.pathname === "/api/inventory/check") { const product = url.searchParams.get("product"); const inventory = await env.INVENTORY_KV.get(product); return new Response(inventory); } // Serve static assets (HTML, CSS, images) return env.ASSETS.fetch(request); },}; ``` index.ts ``` export default { async fetch(request, env) { const url = new URL(request.url); // Check real-time inventory if (url.pathname === '/api/inventory/check') { const product = url.searchParams.get('product'); const inventory = await env.INVENTORY_KV.get(product); return new Response(inventory); } // Serve static assets (HTML, CSS, images) return env.ASSETS.fetch(request); }}; ``` **Get Started:**Upload static assets using the Workers for Platforms API or Wrangler. For more information, visit our [Workers for Platforms documentation. ↗](https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/configuration/static-assets/) Jan 31, 2025 1. ### [Transform HTML quickly with streaming content](https://developers.cloudflare.com/changelog/post/2025-01-31-html-rewriter-streaming/) [ Workers ](https://developers.cloudflare.com/workers/) You can now transform HTML elements with streamed content using [HTMLRewriter](https://developers.cloudflare.com/workers/runtime-apis/html-rewriter). Methods like `replace`, `append`, and `prepend` now accept [Response](https://developers.cloudflare.com/workers/runtime-apis/response/) and [ReadableStream](https://developers.cloudflare.com/workers/runtime-apis/streams/readablestream/)values as [Content](https://developers.cloudflare.com/workers/runtime-apis/html-rewriter/#global-types). This can be helpful in a variety of situations. For instance, you may have a Worker in front of an origin, and want to replace an element with content from a different source. Prior to this change, you would have to load all of the content from the upstream URL and convert it into a string before replacing the element. This slowed down overall response times. Now, you can pass the `Response` object directly into the `replace` method, and HTMLRewriter will immediately start replacing the content as it is streamed in. This makes responses faster. * [ JavaScript ](#tab-panel-4785) * [ TypeScript ](#tab-panel-4786) index.js ``` class ElementRewriter { async element(element) { // able to replace elements while streaming content // the fetched body is not buffered into memory as part // of the replace let res = await fetch("https://upstream-content-provider.example"); element.replace(res); }} export default { async fetch(request, env, ctx) { let response = await fetch("https://site-to-replace.com"); return new HTMLRewriter() .on("[data-to-replace]", new ElementRewriter()) .transform(response); },}; ``` index.ts ``` class ElementRewriter { async element(element: any) { // able to replace elements while streaming content // the fetched body is not buffered into memory as part // of the replace let res = await fetch('https://upstream-content-provider.example'); element.replace(res); }} export default { async fetch(request, env, ctx): Promise { let response = await fetch('https://site-to-replace.com'); return new HTMLRewriter().on('[data-to-replace]', new ElementRewriter()).transform(response); },} satisfies ExportedHandler; ``` For more information, see the [HTMLRewriter documentation](https://developers.cloudflare.com/workers/runtime-apis/html-rewriter). Jan 30, 2025 1. ### [AI Gateway Introduces New Worker Binding Methods](https://developers.cloudflare.com/changelog/post/2025-01-26-worker-binding-methods/) [ AI Gateway ](https://developers.cloudflare.com/ai-gateway/) We have released new [Workers bindings API methods](https://developers.cloudflare.com/ai-gateway/usage/worker-binding-methods/), allowing you to connect Workers applications to AI Gateway directly. These methods simplify how Workers calls AI services behind your AI Gateway configurations, removing the need to use the REST API and manually authenticate. To add an AI binding to your Worker, include the following in your [Wrangler configuration file](https://developers.cloudflare.com/workers/wrangler/configuration/): ![Add an AI binding to your Worker.](https://developers.cloudflare.com/_astro/add-binding.BoYTiyon_ZjdDNx.webp) With the new AI Gateway binding methods, you can now: * Send feedback and update metadata with `patchLog`. * Retrieve detailed log information using `getLog`. * Execute [universal requests](https://developers.cloudflare.com/ai-gateway/usage/universal/) to any AI Gateway provider with `run`. For example, to send feedback and update metadata using `patchLog`: ![Send feedback and update metadata using patchLog:](https://developers.cloudflare.com/_astro/send-feedback.BGRzKmd9_NDVos.webp) Jan 30, 2025 1. ### [Increased Browser Rendering limits!](https://developers.cloudflare.com/changelog/post/2025-01-30-browser-rendering-more-instances/) [ Workers ](https://developers.cloudflare.com/workers/)[ Browser Run ](https://developers.cloudflare.com/browser-run/) [Browser Rendering](https://developers.cloudflare.com/browser-run/) now supports 10 concurrent browser instances per account _and_ 10 new instances per minute, up from the previous limits of 2. This allows you to launch more browser tasks from [Cloudflare Workers](https://developers.cloudflare.com/workers). To manage concurrent browser sessions, you can use [Queues](https://developers.cloudflare.com/queues/) or [Workflows](https://developers.cloudflare.com/workflows/): * [ JavaScript ](#tab-panel-4791) * [ TypeScript ](#tab-panel-4792) index.js ``` export default { async queue(batch, env) { for (const message of batch.messages) { const browser = await puppeteer.launch(env.BROWSER); const page = await browser.newPage(); try { await page.goto(message.url, { waitUntil: message.waitUntil, }); // Process page... } finally { await browser.close(); } } },}; ``` index.ts ``` interface QueueMessage { url: string; waitUntil: number;} export interface Env { BROWSER_QUEUE: Queue; BROWSER: Fetcher;} export default { async queue(batch: MessageBatch, env: Env): Promise { for (const message of batch.messages) { const browser = await puppeteer.launch(env.BROWSER); const page = await browser.newPage(); try { await page.goto(message.url, { waitUntil: message.waitUntil, }); // Process page... } finally { await browser.close(); } } },}; ``` Jan 30, 2025 1. ### [Expanded language support for Stream AI Generated Captions](https://developers.cloudflare.com/changelog/post/2025-01-30-stream-generated-captions-new-languages/) [ Stream ](https://developers.cloudflare.com/stream/) Stream's [generated captions](https://developers.cloudflare.com/stream/edit-videos/adding-captions/#generate-a-caption)leverage Workers AI to automatically transcribe audio and provide captions to the player experience.

Hyperdrive will automatically create the Cloudflare Access, Service Token, and Policies needed to secure and restrict your Cloudflare Tunnel to the Hyperdrive configuration. To create a Hyperdrive for a private database, you can follow the [Hyperdrive documentation](https://developers.cloudflare.com/hyperdrive/configuration/connect-to-private-database/). You can still manually create the Cloudflare Access, Service Token, and Policies if you prefer. This feature is available from the Cloudflare dashboard. Jan 28, 2025 1. ### [Workers KV namespace limits increased to 1000](https://developers.cloudflare.com/changelog/post/2025-01-27-kv-increased-namespaces-limits/) [ KV ](https://developers.cloudflare.com/kv/) You can now have up to 1000 Workers KV namespaces per account. Workers KV namespace limits were increased from 200 to 1000 for all accounts. Higher limits for Workers KV namespaces enable better organization of key-value data, such as by category, tenant, or environment. Consult the [Workers KV limits documentation](https://developers.cloudflare.com/kv/platform/limits/) for the rest of the limits. This increased limit is available for both the Free and Paid [Workers plans](https://developers.cloudflare.com/workers/platform/pricing/). Jan 28, 2025 1. ### [Support for Node.js DNS, Net, and Timer APIs in Workers](https://developers.cloudflare.com/changelog/post/2025-01-28-nodejs-compat-improvements/) [ Workers ](https://developers.cloudflare.com/workers/) When using a Worker with the [nodejs\_compat](https://developers.cloudflare.com/workers/runtime-apis/nodejs/) compatibility flag enabled, you can now use the following Node.js APIs: * [node:net](https://developers.cloudflare.com/workers/runtime-apis/nodejs/net/) * [node:dns](https://developers.cloudflare.com/workers/runtime-apis/nodejs/dns/) * [node:timers](https://developers.cloudflare.com/workers/runtime-apis/nodejs/timers/) #### node:net You can use [node:net ↗](https://nodejs.org/api/net.html) to create a direct connection to servers via a TCP sockets with [net.Socket ↗](https://nodejs.org/api/net.html#class-netsocket). * [ JavaScript ](#tab-panel-4789) * [ TypeScript ](#tab-panel-4790) index.js ``` import net from "node:net"; const exampleIP = "127.0.0.1"; export default { async fetch(req) { const socket = new net.Socket(); socket.connect(4000, exampleIP, function () { console.log("Connected"); }); socket.write("Hello, Server!"); socket.end(); return new Response("Wrote to server", { status: 200 }); },}; ``` index.ts ``` import net from "node:net"; const exampleIP = "127.0.0.1"; export default { async fetch(req): Promise { const socket = new net.Socket(); socket.connect(4000, exampleIP, function () { console.log("Connected"); }); socket.write("Hello, Server!"); socket.end(); return new Response("Wrote to server", { status: 200 }); },} satisfies ExportedHandler; ``` Additionally, you can now use other APIs including [net.BlockList ↗](https://nodejs.org/api/net.html#class-netblocklist) and [net.SocketAddress ↗](https://nodejs.org/api/net.html#class-netsocketaddress).

Cloudflare automatically selects a single, optimal tiered data center for all origins in your Load Balancing Pool. #### How it works When you use [Load Balancing](https://developers.cloudflare.com/load-balancing/) with [Smart Tiered Cache](https://developers.cloudflare.com/cache/how-to/tiered-cache/), Cloudflare analyzes performance metrics across your pool's origins and automatically selects the optimal Upper Tier data center for the entire pool. This means: * **Consistent cache location**: All origins in the pool share the same Upper Tier cache. * **Higher HIT rates**: Requests for the same content hit the cache more frequently. * **Reduced origin requests**: Fewer requests reach your origin servers. * **Improved performance**: Faster response times for cache HITs. #### Example workflow ``` Load Balancing Pool: api-pool├── Origin 1: api-1.example.com├── Origin 2: api-2.example.com└── Origin 3: api-3.example.com ↓Selected Upper Tier: [Optimal data center based on pool performance] ``` #### Get started To get started, enable [Smart Tiered Cache](https://developers.cloudflare.com/cache/how-to/tiered-cache/) on your zone and configure your [Load Balancing Pool](https://developers.cloudflare.com/load-balancing/). ```json {"@context":"https://schema.org","@type":"BlogPosting","@id":"https://developers.cloudflare.com/changelog/38/#page","headline":"Changelogs | Cloudflare Docs","url":"https://developers.cloudflare.com/changelog/38/","inLanguage":"en","image":"https://developers.cloudflare.com/cf-twitter-card.png","publisher":{"@type":"Organization","name":"Cloudflare","url":"https://www.cloudflare.com/"},"isPartOf":{"@type":"WebSite","@id":"https://developers.cloudflare.com/#website","name":"Cloudflare Docs","url":"https://developers.cloudflare.com/"}} ```
