Cloudflare Release Notes

The Markdown Conversion service now supports a new output conversion option that controls the format of the converted content.

Set output.format to text to receive plain text with Markdown syntax removed. The default value is markdown, so existing conversions are unchanged.

Use the env.AI binding:

await env.AI.toMarkdown(
	{ name: "page.html", blob: new Blob([html]) },
	{
		conversionOptions: {
			output: { format: "text" },
		},
	},
);

await env.AI.toMarkdown(
	{ name: "page.html", blob: new Blob([html]) },
	{
		conversionOptions: {
			output: { format: "text" },
		},
	},
);

Or call the REST API:

curl https://api.cloudflare.com/client/v4/accounts/{ACCOUNT_ID}/ai/tomarkdown \
  -H 'Authorization: Bearer {API_TOKEN}' \
  -F 'files=@index.html' \
  -F 'conversionOptions={"output": {"format": "text"}}'

When you request text output, the format field of each result is set to text. For more details, refer to Conversion Options.

Digital Experience Monitoring (DEX) provides visibility into device, network, and application performance across your Cloudflare SASE deployment.

The Device Monitoring page now analyzes hardware and network data between a Cloudflare One Client device and Cloudflare's edge, so you can diagnose connectivity and performance issues. Previously, this data was only available in raw DEX Device State Event logs, which required you to build your own analytics to interpret it.

Device Monitoring summary with connection status, connection mode, Wi-Fi signal strength, traffic performance, and device health

A summary at the top of the page shows the health of each category at a glance, using Good, Fair, and Poor labels:

• Connection — connection status, Cloudflare One Client mode, and tunnel type over time
• Wi-Fi signal strength — signal measured in dBm over time, with thresholds that flag a weak signal
• Traffic performance — upstream and downstream performance, including network throughput on the active interface
• Device health — hardware metrics such as CPU, memory, and disk …

On October 5, 2026, two changes take effect across the Zero Trust Networks API and Cloudflare Tunnel API: the CIDR-encoded route endpoints are removed, and tunnel list and get responses no longer include the connections field. If you manage private network routes or read tunnel connection details through the API, cloudflared, Terraform, or another integration, review the changes in the following sections and migrate before the removal date.

Route endpoints

The CIDR-encoded route endpoints are deprecated in favor of the standard, route_id-based endpoints that already exist today. Both sets of endpoints route a private network through Cloudflare Tunnel or Cloudflare Mesh (the API still refers to Mesh nodes as warp_connector) — only the request shape changes.

Deprecated endpoints (removed October 5, 2026):

• Create a tunnel route (CIDR Endpoint): POST /accounts/{account_id}/teamnet/routes/network/{ip_network_encoded} …

With Workflows, you can configure built-in retry behavior for each step. Previously, you could configure step retries with fixed delay durations, such as seconds, minutes, or hours, and backoff strategies such as constant, linear, or exponential.

Step retries now support dynamic delay functions. Instead of choosing only a base delay and backoff strategy, pass a function to retries.delay and calculate the next delay from the failed attempt and thrown error.

This is useful when retries should depend on the failure. Your Workflow may need to wait longer after a rate-limit error, but retry sooner after a short network failure. The delay function can also accommodate provider guidance if, for example, a downstream API returns a Retry-After value in its error messaging.

await step.do(
	"sync customer",
	{
		retries: {
			limit: 5,
			delay: ({ ctx, error }) => {
				if (error.message.includes("rate limit")) {
					return `${ctx.attempt * 30} seconds`;
				}

				return "10 seconds";
			},
		},
	},
	async () => {
		await syncCustomer();
	},
);

await step.do(
	"sync customer",
	{
		retries: {
			limit: 5,
			delay: ({ ctx, error }) => {
				if (error.message.includes("rate limit")) {
					return `${ctx.attempt * 30} seconds`;
				}

				return "10 seconds";
			},
		},
	},
	async () => {
		await syncCustomer();
	},
);
``` …

If your account does not already have a key-value (KV) backed Durable Object namespace, you can no longer create new ones. New Durable Object namespaces must use the SQLite storage backend, which has been recommended for all new Durable Objects since it became generally available ↗︎ in 2024.

Create a new class with a new_sqlite_classes migration:

{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "migrations": [
    {
      "tag": "v1",
      "new_sqlite_classes": [
        "MyDurableObject"
      ]
    }
  ]
}

[[migrations]]
tag = "v1"
new_sqlite_classes = ["MyDurableObject"]

SQLite-backed Durable Objects have feature parity with the key-value backend — including the key-value storage API — and additionally support relational SQL queries and point-in-time recovery to restore an object's storage to any point in the past 30 days. …

Wrangler now collects npm package dependency information from your project's package.json during wrangler deploy and wrangler versions upload, and includes it in the upload metadata sent to the Cloudflare API. This data, each dependency's name, declared version range, and exact installed version, enables dependency analytics and future supply chain security features such as vulnerability alerting.

To opt out, set dependencies_instrumentation.enabled to false in your Wrangler configuration file:

{
	"dependencies_instrumentation": {
		"enabled": false
	}
}

[dependencies_instrumentation]
enabled = false

For more details, refer to Wrangler configuration.

The DNS Firewall page in the Cloudflare dashboard has been refreshed, bringing several settings that were previously API-only into the UI and modernizing how you view and manage your DNS Firewall clusters.

New DNS Firewall UX

What is new

• More settings in the dashboard: cluster options that were previously only configurable through the API — such as attack mitigation, rate limiting, negative TTL, and resolver subnet — are now available directly in the dashboard.
• Better table experience: the DNS Firewall cluster table has been revised to surface cluster details at a glance, with resizable columns and the option to show or hide columns to tailor the view to your workflow.
• New create and edit UX: adding and editing clusters now uses a modernized form that groups related settings together, making configuration faster and clearer.

Availability

Available to all DNS Firewall customers as part of their existing subscription.

Where to find it

In the Cloudflare dashboard, go to the DNS Firewall page.

Go to Clusters ↗

For more information, refer to DNS Firewall.

Cloudflare IPsec now supports the IKE_SA_INIT_FULL_TRANSCRIPT_AUTH ↗︎ IKEv2 extension to protect against downgrade attacks on IPsec tunnels.

IKEv2's original authentication design has each endpoint sign only its own outbound messages, not the full handshake transcript. A quantum-capable on-path attacker ↗︎ can exploit this to bypass post-quantum key exchange by downgrading the connection to classical cryptography. The IKE_SA_INIT_FULL_TRANSCRIPT_AUTH extension addresses this by having both peers sign the entire handshake transcript during the authentication exchange, preventing an attacker from manipulating the negotiation without detection.

Key details:

• Available in beta for Cloudflare WAN and Magic Transit IPsec tunnels.
• Cloudflare sends the IKE_SA_INIT_FULL_TRANSCRIPT_AUTH notification unconditionally as a responder when the feature flag is enabled.
• Both the initiator (your device) and responder (Cloudflare) must support the extension for downgrade protection to be effective.
• This feature is currently gated by a per-account feature flag. Contact your account team to turn it on.

Refer to Downgrade protection for more details.

Cloudflare Advanced Network Firewall IP lists, IDS, and SIP rules are now supported for accounts using Unified Routing mode. These features require a Cloudflare Advanced Network Firewall subscription.

Support for additional features - Threat Intel Lists, Rate Limiting, and Managed Rulesets - is planned.

For the full list of current beta limitations, refer to Traffic steering beta limitations.

In AI Search, you can upload files to an instance, or connect a data source such as an R2 bucket, to make your content searchable with natural language. Each file becomes an item identified by an object key (its filename or path). The list items endpoint returns the items in an instance.

That endpoint now accepts a key query parameter, so you can look up a single item by its exact object key without paging through the full list. This complements the existing item_id filter for when you know the key but not the ID.

curl "https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/ai-search/instances/<INSTANCE_NAME>/items?key=docs/readme.md" \
  -H "Authorization: Bearer <API_TOKEN>"

Keys are unique per data source, so combine key with source (for example, source=builtin) to disambiguate when the same key exists across multiple sources.

For more information, refer to managing items.

Workers AI Markdown conversion (toMarkdown) now supports .gif and .bmp image files, in addition to the JPEG, PNG, WebP, and SVG formats already supported.

GIF and BMP files run through the same image pipeline as other formats. Each image is resized if needed (and for animated GIFs, only the first frame is used), then passed to an object-detection model to identify what it contains. Those detected objects prompt a vision model that writes a natural-language description of the image, which becomes searchable, machine-readable Markdown.

AI Search uses toMarkdown automatically to process the files it ingests, so any .gif and .bmp files are included the next time your index syncs, with no configuration changes required. This helps when your content mixes formats, for example a support knowledge base full of screenshots or an archive of BMP scans.

Learn more about Markdown conversion and the full list of AI Search's supported file types.

You can now query your R2 Data Catalog tables with R2 SQL directly from the Cloudflare dashboard, without installing a CLI or wiring up a client. This makes it easy to explore your Apache Iceberg ↗︎ data, validate queries, and inspect results in one place.

R2 SQL Query Editor

To get started, go to R2 Data Catalog ↗︎ in the Cloudflare dashboard and select Query data to launch the built-in SQL editor. From there you can:

• Write and run queries interactively — Iterate on R2 SQL directly in the browser with syntax highlighting and autocomplete, instead of re-running commands through Wrangler or the REST API.
• Explore your data — Explore your namespaces and tables alongside the editor so you can discover what's queryable without leaving the page or using other tools.
• Understand results and performance — View result sets with per-query statistics, export them, and get helpful EXPLAIN outputs to see exactly how a query runs.

Note

Your R2 SQL credential is generated and stored for you and can be rotated in the R2 Data Catalog settings page.

Partnering with Moondream ↗︎ to bring their latest model @cf/moondream/moondream3.1-9B-A2B to Workers AI. Moondream 3.1 is a fast vision language model built on a mixture-of-experts architecture with 9B total parameters and 2B active, delivering frontier-level visual reasoning while retaining fast, cost-efficient inference.

Moondream 3.1 is designed for real-world vision tasks, with a 32K token context window for handling complex queries and structured outputs.

Key capabilities

• Query — ask open-ended questions about an image, with an optional reasoning parameter
• Caption — generate short, normal, or long descriptions of an image
• Point — return coordinates for objects matching a target phrase
• Detect — return bounding boxes for objects matching a target phrase

Real-time vision at the edge

Vision workloads like live camera feeds, robotics, content moderation, and interactive agents need answers in milliseconds, not seconds. Moondream 3.1's small active footprint (2B active parameters) pairs well with Workers AI's serverless, globally distributed inference: requests run close to your users, and streaming responses start returning tokens almost immediately. …

Cloudflare Drop ↗︎ lets you deploy a static site to Cloudflare without requiring a Cloudflare account to get started.

Cloudflare Drag and Drop upload screen for browsing folders or ZIP files

Upload a folder or zip file of static assets (static HTML, CSS, JavaScript, images, and fonts) and get a temporary live preview that stays live for 1 hour. During that window, you can test the site, share the preview URL, or claim the deployment to keep it.

Cloudflare Drag and Drop temporary live preview screen with claim and copy claim link actions

When you are ready to make the deployment permanent, click Claim to sign in or create a Cloudflare account. You can claim the site into an existing Cloudflare account or create a new account for the deployment.

Note

If you are creating a new account, you will need to verify your email address before continuing. …

Cloudflare Advanced Network Firewall IP lists, IDS, and SIP rules are now supported for accounts using Unified Routing mode. These features require a Cloudflare Advanced Network Firewall subscription.

Support for additional features - Threat Intel Lists, Rate Limiting, and Managed Rulesets - is planned.

You can now configure file transfer controls for browser-based RDP with Cloudflare Access, allowing you to restrict whether users can upload or download files between their local machine and the remote Windows server.

File transfer connection settings in the Access policy configuration.

This feature is useful for organizations that support bring-your-own-device (BYOD) policies or third-party contractors using unmanaged devices. By restricting file transfers, you can prevent sensitive data from being moved out of the remote session to a user's personal device.

Configuration options

File transfer controls are configured per policy within your Access application, alongside existing text clipboard controls. For each policy, you can select one of the following options:

• Client to remote RDP session allowed — Users can upload files from their local machine into the browser-based RDP session.
• Remote RDP session to client allowed — Users can download files from the browser-based RDP session to their local machine.
• Both directions allowed — Users can upload and download files between their local machine and the browser-based RDP session. …

Browser Isolation now supports Gateway authorization proxy endpoints. You can apply HTTP Isolate policies to traffic routed through authorization proxy endpoints, the same way you can for traffic from the Cloudflare One Client.

Previously, only source IP proxy endpoints supported Browser Isolation, and only with non-identity policies. Because authorization proxy endpoints authenticate users through an identity provider, you can now apply identity-based Isolate policies to PAC file-proxied traffic without requiring the Cloudflare One Client.

To get started, create an authorization proxy endpoint and build an Isolate policy.
