Cloudflare Release Notes

You can now use CASB to find security misconfigurations in your AWS cloud environment using Data Loss Prevention.

You can also connect your AWS compute account to extract and scan your S3 buckets for sensitive data while avoiding egress fees. CASB will scan any objects that exist in the bucket at the time of configuration.

To connect a compute account to your AWS integration:

1. In Cloudflare One ↗︎, go to Cloud & SaaS findings > Integrations.
2. Find and select your AWS integration.
3. Select Open connection instructions.
4. Follow the instructions provided to connect a new compute account.
5. Select Refresh.

Now, you can use Cloud Connector to route traffic to your R2 buckets based on URLs, headers, geolocation, and more.

Example setup:

curl --request PUT \
"https://api.cloudflare.com/client/v4/zones/{zone_id}/cloud_connector/rules" \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '[
  {
    "expression": "http.request.uri.path wildcard \"/images/*\"",
    "provider": "cloudflare_r2",
    "description": "Connect to R2 bucket containing images",
    "parameters": {
      "host": "mybucketcustomdomain.example.com"
    }
  }
]'

Get started using Cloud Connector documentation.

You can now reduce latency and lower R2 egress costs automatically when using Smart Tiered Cache with R2. Cloudflare intelligently selects a tiered data center close to your R2 bucket location, creating an efficient caching topology without additional configuration.

How it works

When you enable Smart Tiered Cache for zones using R2 as an origin, Cloudflare automatically:

1. Identifies your R2 bucket location: Determines the geographical region where your R2 bucket is stored.
2. Selects an optimal Upper Tier: Chooses a data center close to your bucket as the common Upper Tier cache.
3. Routes requests efficiently: All cache misses in edge locations route through this Upper Tier before reaching R2.

Benefits

• Automatic optimization: No manual configuration required.
• Lower egress costs: Fewer requests to R2 reduce egress charges.
• Improved hit ratio: Common Upper Tier increases cache efficiency.
• Reduced latency: Upper Tier proximity to R2 minimizes fetch times.

Get started

To get started, enable Smart Tiered Cache on your zone using R2 as an origin.

You can now use the cache property of the Request interface to bypass Cloudflare's cache when making subrequests from Cloudflare Workers, by setting its value to no-store.

index.jsjs

export default {
	async fetch(req, env, ctx) {
		const request = new Request("https://cloudflare.com", {
			cache: "no-store",
		});
		const response = await fetch(request);
		return response;
	},
};

index.tsts

export default {
  async fetch(req, env, ctx): Promise<Response> {
		const request = new Request("https://cloudflare.com", { cache: 'no-store'});
		const response = await fetch(request);
    return response;
  }
} satisfies ExportedHandler<Environment>

When you set the value to no-store on a subrequest made from a Worker, the Cloudflare Workers runtime will not check whether a match exists in the cache, and not add the response to the cache, even if the response includes directives in the Cache-Control HTTP header that otherwise indicate that the response is cacheable. …

You can now send user action logs for Email security to an endpoint of your choice with Cloudflare Logpush.

Filter logs matching specific criteria you have set or select from multiple fields you want to send. For all users, we will log the date and time, user ID, IP address, details about the message they accessed, and what actions they took.

When creating a new Logpush job, remember to select Audit logs as the dataset and filter by:

• Field: "ResourceType"
• Operator: "starts with"
• Value: "email_security".

Logpush-user-actions

For more information, refer to Enable user action logs.

This feature is available across all Email security packages:

• Enterprise
• Enterprise + PhishGuard

You can now stage and test cache configurations before deploying them to production. Versioned environments let you safely validate cache rules, purge operations, and configuration changes without affecting live traffic.

How it works

With versioned environments, you can:

1. Create staging versions of your cache configuration.
2. Test cache rules in a non-production environment.
3. Purge staged content independently from production.
4. Validate changes before promoting to production.

This capability integrates with Cloudflare's broader versioning system, allowing you to manage cache configurations alongside other zone settings.

Benefits

• Risk-free testing: Validate configuration changes without impacting production.
• Independent purging: Clear staging cache without affecting live content.
• Deployment confidence: Catch issues before they reach end users.
• Team collaboration: Multiple team members can work on different versions.

Get started

To get started, refer to the version management documentation.

Important limitation

Cache Reserve is only supported for your production environment. Staged environments can use standard cache functionality, but Cache Reserve persistence is limited to production deployments.

Enterprise customers can now optimize cache hit ratios for content that varies by device, language, or referrer by sharding cache using up to ten values from previously restricted headers with custom cache keys.

How it works

When configuring custom cache keys, you can now include values from these headers to create distinct cache entries:

• accept* headers (for example, accept, accept-encoding, accept-language): Serve different cached versions based on content negotiation.
• referer header: Cache content differently based on the referring page or site.
• user-agent header: Maintain separate caches for different browsers, devices, or bots.

When to use cache sharding

• Content varies significantly by device type (mobile vs desktop).
• Different language or encoding preferences require distinct responses.
• Referrer-specific content optimization is needed.

Example configuration

{
  "cache_key": {
    "custom_key": {
      "header": {
        "include": ["accept-language", "user-agent"],
        "check_presence": ["referer"]
      }
    }
  }
}
``` …

Workflows is now in open beta, and available to any developer a free or paid Workers plan.

Workflows allow you to build multi-step applications that can automatically retry, persist state and run for minutes, hours, days, or weeks. Workflows introduces a programming model that makes it easier to build reliable, long-running tasks, observe as they progress, and programmatically trigger instances based on events across your services.

Get started

You can get started with Workflows by following our get started guide and/or using npm create cloudflare to pull down the starter project:

npm create cloudflare@latest workflows-starter -- --template "cloudflare/workflows-starter"

You can open the src/index.ts file, extend it, and use wrangler deploy to deploy your first Workflow. From there, you can:

• Learn the Workflows API
• Trigger Workflows via your Workers apps.
• Understand the Rules of Workflows and how to adopt best practices

It’s now easy to create wildcard-based URL Rewrites. No need for complex functions—just define your patterns and go.

Rules Overview Interface

What’s improved:

• Full wildcard support – Create rewrite patterns using intuitive interface.
• Simplified rule creation – No need for complex functions.

Try it via creating a Rewrite URL rule in the dashboard.

Cloudflare has introduced new fields to two Gateway-related datasets in Cloudflare Logs:

• Gateway HTTP: ApplicationIDs, ApplicationNames, CategoryIDs, CategoryNames, DestinationIPContinentCode, DestinationIPCountryCode, ProxyEndpoint, SourceIPContinentCode, SourceIPCountryCode, VirtualNetworkID, and VirtualNetworkName.

• Gateway Network: ApplicationIDs, ApplicationNames, DestinationIPContinentCode, DestinationIPCountryCode, ProxyEndpoint, SourceIPContinentCode, SourceIPCountryCode, TransportProtocol, VirtualNetworkID, and VirtualNetworkName.

Organizations can now eliminate long-lived credentials from their SSH setup and enable strong multi-factor authentication for SSH access, similar to other Access applications, all while generating access and command logs.

SSH with Access for Infrastructure uses short-lived SSH certificates from Cloudflare, eliminating SSH key management and reducing the security risks associated with lost or stolen keys. It also leverages a common deployment model for Cloudflare One customers: WARP-to-Tunnel.

SSH with Access for Infrastructure enables you to:

• Author fine-grained policy to control who may access your SSH servers, including specific ports, protocols, and SSH users.
• Monitor infrastructure access with Access and SSH command logs, supporting regulatory compliance and providing visibility in case of security breach.
• Preserve your end users' workflows. SSH with Access for Infrastructure supports native SSH clients and does not require any modifications to users’ SSH configs.

Every site on Cloudflare now has access to AI Audit, which summarizes the crawling behavior of popular and known AI services.

You can use this data to:

• Understand how and how often crawlers access your site (and which content is the most popular).
• Block specific AI bots accessing your site.
• Use Cloudflare to enforce your robots.txt policy via an automatic WAF rule.

View AI bot activity with AI Audit

To get started, explore AI audit.

You can now create optimized cache rules instantly with one-click templates, eliminating the complexity of manual rule configuration.

How it works

2. Select a template for your use case.
3. Click to apply the template with sensible defaults.
4. Customize as needed for your specific requirements.

Available cache templates

• Cache everything: Adjust the cache level for all requests.
• Bypass cache for everything: Bypass cache for all requests.
• Cache default file extensions: Replicate Page Rules caching behavior by making only default extensions eligible for cache.
• Bypass cache on cookie: Bypass cache for requests containing specific cookies.
• Set edge cache time: Cache responses with status code between 200 and 599 on the Cloudflare edge.
• Set browser cache time: Adjust how long a browser should cache a resource.

Get started

To get started, go to Rules > Templates ↗︎ in the dashboard. For more information, refer to the Cache Rules documentation.

You can now achieve higher cache hit ratios with Generic Global Tiered Cache. Regional content hashing routes content consistently to the same upper-tier data centers, eliminating redundant caching and reducing origin load.

How it works

Regional content hashing groups data centers by region and uses consistent hashing to route content to designated upper-tier caches:

• Same content always routes to the same upper-tier data center within a region.
• Eliminates redundant copies across multiple upper-tier caches.
• Increases the likelihood of cache HITs for the same content.

Example

A popular image requested from multiple edge locations in a region:

• Before: Cached at 3-4 different upper-tier data centers
• After: Cached at 1 designated upper-tier data center
• Result: 3-4x fewer cache MISSes, reducing origin load and improving performance

Get started

To get started, enable Generic Global Tiered Cache on your zone.
