## WARP client for Linux (version 2025.8.779.0)

Oct 07, 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 significant fixes and improvements including an updated public key for Linux packages. The public key must be updated if it was installed before September 12, 2025 to ensure the repository remains functional after December 4, 2025. Instructions to make this update are available at [pkg.cloudflareclient.com](https://pkg.cloudflareclient.com/).

**Changes and improvements**

* [Proxy mode](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/configure-warp/warp-modes/#proxy-mode) has been enhanced for even faster resolution. Proxy mode now supports SOCKS4, SOCK5, and HTTP CONNECT over an L4 tunnel with custom congestion control optimizations instead of the previous L3 tunnel to Cloudflare's network. This has more than doubled Proxy mode throughput in lab speed testing, by an order of magnitude in some cases.

* The MASQUE protocol is now the only protocol that can use [Proxy mode](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/configure-warp/warp-modes/#proxy-mode). If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or switch to the MASQUE protocol. Otherwise, all devices matching the profile will lose connectivity.

**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).
