## WARP client for Linux (version 2025.5.893.0)

Jun 30, 2025

[Zero Trust WARP Client](https://developers.cloudflare.com/cloudflare-one/connections/connect-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/connections/connect-devices/warp/download-warp/).

This release contains improvements and new exciting features, including [post-quantum cryptography](https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/deployment/mdm-deployment/parameters/#enable_post_quantum). By tunneling your corporate network traffic over Cloudflare, you can now gain the immediate protection of post-quantum cryptography without needing to upgrade any of your individual corporate applications or systems.

**Changes and improvements**

* Fixed a device registration issue causing WARP connection failures when changing networks.

* Captive portal improvements and fixes:

  * Captive portal sign in notifications will now be sent through operating system notification services.
  * Fix for firewall configuration issue affecting clients in DoH only mode.

* Improved the connectivity status message in the client GUI.

* The WARP client now applies post-quantum cryptography end-to-end on enabled devices accessing resources behind a Cloudflare Tunnel. This feature can be [enabled by MDM](https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/deployment/mdm-deployment/parameters/#enable_post_quantum).

* Improvement to handle client configuration changes made by MDM while WARP is not running.

* Fixed an issue affecting Split Tunnel Include mode, where traffic outside the tunnel was blocked when switching between Wi-Fi and Ethernet networks.

* Added a WARP client device posture check for SAN attributes to the [client certificate check](https://developers.cloudflare.com/cloudflare-one/identity/devices/warp-client-checks/client-certificate/).

**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/connections/connect-devices/warp/configure-warp/route-traffic/local-domains/#route-traffic-to-fallback-server).
