1. Removed unused meta fields from DNS records

   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": "<ID>",
       "zone_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": []
   }

1. Workers for Platforms now supports Static Assets

   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

   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);
     },
   };

   TypeScript

   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. ↗

1. Transform HTML quickly with streaming content

   Workers

   You can now transform HTML elements with streamed content using HTMLRewriter.

   Methods like replace, append, and prepend now accept Response and ReadableStream values as Content.

   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

   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);
     },
   };

   TypeScript

   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<Response> {
       let response = await fetch('https://site-to-replace.com');
       return new HTMLRewriter().on('[data-to-replace]', new ElementRewriter()).transform(response);
     },
   } satisfies ExportedHandler<Env>;

   For more information, see the HTMLRewriter documentation.

1. AI Gateway Introduces New Worker Binding Methods

   AI Gateway

   We have released new Workers bindings API 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:

   

   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 to any AI Gateway provider with run.

   For example, to send feedback and update metadata using patchLog:

1. Increased Browser Rendering limits!

   Workers Browser Rendering

   Browser Rendering 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.

   To manage concurrent browser sessions, you can use Queues or Workflows:

   JavaScript

   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();
         }
       }
     },
   };

   TypeScript

   index.ts

   interface QueueMessage {
     url: string;
     waitUntil: number;
   }
   
   export interface Env {
     BROWSER_QUEUE: Queue<QueueMessage>;
     BROWSER: Fetcher;
   }
   
   export default {
     async queue(batch: MessageBatch<QueueMessage>, env: Env): Promise<void> {
       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();
         }
       }
     }
   };

1. Automatic configuration for private databases on Hyperdrive

   Hyperdrive

   Hyperdrive now automatically configures your Cloudflare Tunnel to connect to your private database.

   

   When creating a Hyperdrive configuration for a private database, you only need to provide your database credentials and set up a Cloudflare Tunnel within the private network where your database is accessible. 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. 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

   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 for the rest of the limits. This increased limit is available for both the Free and Paid Workers plans.

1. Support for Node.js DNS, Net, and Timer APIs in Workers

   Workers

   When using a Worker with the nodejs_compat compatibility flag enabled, you can now use the following Node.js APIs:

   • node:net
   • node:dns
   • node:timers

   node:net

   You can use node:net ↗ to create a direct connection to servers via a TCP sockets with net.Socket ↗.

   JavaScript

   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 });
     },
   };

   TypeScript

   index.ts

   import net from "node:net";
   
   const exampleIP = "127.0.0.1";
   
   export default {
     async fetch(req): Promise<Response> {
       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 ↗ and net.SocketAddress ↗.

   Note that net.Server ↗ is not supported.

   node:dns

   You can use node:dns ↗ for name resolution via DNS over HTTPS using Cloudflare DNS ↗ at 1.1.1.1.

   JavaScript

   index.js

   import dns from "node:dns";
   
   let response = await dns.promises.resolve4("cloudflare.com", "NS");

   TypeScript

   index.ts

   import dns from 'node:dns';
   
   let response = await dns.promises.resolve4('cloudflare.com', 'NS');

   All node:dns functions are available, except lookup, lookupService, and resolve which throw "Not implemented" errors when called.

   node:timers

   You can use node:timers ↗ to schedule functions to be called at some future period of time.

   This includes setTimeout ↗ for calling a function after a delay, setInterval ↗ for calling a function repeatedly, and setImmediate ↗ for calling a function in the next iteration of the event loop.

   JavaScript

   index.js

   import timers from "node:timers";
   
   console.log("first");
   timers.setTimeout(() => {
     console.log("last");
   }, 10);
   
   timers.setTimeout(() => {
     console.log("next");
   });

   TypeScript

   index.ts

   import timers from "node:timers";
   
   console.log("first");
   timers.setTimeout(() => {
     console.log("last");
   }, 10);
   
   timers.setTimeout(() => {
     console.log("next");
   });

1. Increased Workflows limits and improved instance queueing.

   Workflows

   Workflows (beta) now allows you to define up to 1024 steps. sleep steps do not count against this limit.

   We've also added:

   • instanceId as property to the WorkflowEvent type, allowing you to retrieve the current instance ID from within a running Workflow instance
   • Improved queueing logic for Workflow instances beyond the current maximum concurrent instances, reducing the cases where instances are stuck in the queued state.
   • Support for pause and resume for Workflow instances in a queued state.

   We're continuing to work on increases to the number of concurrent Workflow instances, steps, and support for a new waitForEvent API over the coming weeks.

1. Smart Tiered Cache optimizes Load Balancing Pools

   Cache / CDN

   You can now achieve higher cache hit rates and reduce origin load when using Load Balancing with Smart Tiered Cache. 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 with Smart 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 on your zone and configure your Load Balancing Pool.

1. 40-60% Faster D1 Worker API Requests

   D1

   Users making D1 requests via the Workers API can see up to a 60% end-to-end latency improvement due to the removal of redundant network round trips needed for each request to a D1 database.

   

   p50, p90, and p95 request latency aggregated across entire D1 service. These latencies are a reference point and should not be viewed as your exact workload improvement.

   This performance improvement benefits all D1 Worker API traffic, especially cross-region requests where network latency is an outsized latency factor. For example, a user in Europe talking to a database in North America. D1 location hints can be used to influence the geographic location of a database.

   For more details on how D1 removed redundant round trips, see the D1 specific release note entry.

1. Faster Workers Builds with Build Caching and Watch Paths

   Workers
   

   Workers Builds, the integrated CI/CD system for Workers (currently in beta), now lets you cache artifacts across builds, speeding up build jobs by eliminating repeated work, such as downloading dependencies at the start of each build.

   • Build Caching: Cache dependencies and build outputs between builds with a shared project-wide cache, ensuring faster builds for the entire team.

   • Build Watch Paths: Define paths to include or exclude from the build process, ideal for monorepos to target only the files that need to be rebuilt per Workers project.

   To get started, select your Worker on the Cloudflare dashboard ↗ then go to Settings > Builds, and connect a GitHub or GitLab repository. Once connected, you'll see options to configure Build Caching and Build Watch Paths.

   After you triage your users' submissions (that are machine reviewed), you can now escalate them to our team for reclassification (which are instead human reviewed). User submissions from the submission alias, PhishNet, and our API can all be escalated.

   

   From Reclassifications, go to User submissions. Select the three dots next to any of the user submissions, then select Escalate to create a team request for reclassification. The Cloudflare dashboard will then show you the submissions on the Team Submissions tab.

   Refer to User submissions to learn more about this feature.

   This feature is available across these Email security packages:

   • Advantage
   • Enterprise
   • Enterprise + PhishGuard

1. Increased transparency for phishing email submissions

   Email security

   You now have more transparency about team and user submissions for phishing emails through a Reclassification tab in the Zero Trust dashboard.

   Reclassifications happen when users or admins submit a phish to Email security. Cloudflare reviews and - in some cases - reclassifies these emails based on improvements to our machine learning models.

   This new tab increases your visibility into this process, allowing you to view what submissions you have made and what the outcomes of those submissions are.

1. Establish BGP peering over Direct CNI circuits

   Magic Transit Cloudflare WAN Network Interconnect

   Magic WAN and Magic Transit customers can use the Cloudflare dashboard to configure and manage BGP peering between their networks and their Magic routing table when using a Direct CNI on-ramp.

   Using BGP peering allows customers to:

   • Automate the process of adding or removing networks and subnets.
   • Take advantage of failure detection and session recovery features.

   With this functionality, customers can:

   • Establish an eBGP session between their devices and the Magic WAN / Magic Transit service when connected via CNI.
   • Secure the session by MD5 authentication to prevent misconfigurations.
   • Exchange routes dynamically between their devices and their Magic routing table.

   Refer to Magic WAN BGP peering or Magic Transit BGP peering to learn more about this feature and how to set it up.
