## WARP client for Linux (version 2025.4.929.0)

May 12, 2025

[Zero Trust WARP Client](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/)

A new GA release for the Linux WARP client is now available on the [stable releases downloads page](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/download-warp/).

This release contains two significant changes all customers should be aware of:

1. All DNS traffic now flows inside the WARP tunnel. Customers are no longer required to configure their local firewall rules to allow our [DoH IP addresses and domains](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/deployment/firewall/#doh-ip).
2. When using MASQUE, the connection will fall back to HTTP/2 (TCP) when we detect that HTTP/3 traffic is blocked. This allows for a much more reliable connection on some public WiFi networks.

**Changes and improvements**

* Fixed an issue where the managed network policies could incorrectly report network location beacons as missing.
* Improved DEX test error reporting.
* Fixed an issue causing client notifications to fail in IPv6 only environments which prevented the client from receiving configuration changes to settings like device profile.
* Added a TCP fallback for the MASQUE tunnel protocol to improve connectivity on networks that block UDP or HTTP/3 specifically.
* Added new IP addresses for [tunnel connectivity checks](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/deployment/firewall/#connectivity-checks). If your organization uses a firewall or other policies you will need to exempt these IPs.
* Fixed an issue where frequent network changes could cause WARP to become unresponsive.
* DNS over HTTPS traffic is now included in the WARP tunnel by default.
* Improvement for WARP to check if tunnel connectivity fails or times out at device wake before attempting to reconnect.
* Fixed an issue causing WARP connection disruptions after network changes.

**Known issues**

* Devices using WARP client 2025.4.929.0 and up may experience Local Domain Fallback failures if a fallback server has not been configured. To configure a fallback server, refer to [Route traffic to fallback server](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/configure-warp/route-traffic/local-domains/#route-traffic-to-fallback-server).
