+title: WARP client for Linux (version 2025.4.929.0)
+description: WARP client for Linux (version 2025.4.929.0)
+date: 2025-05-12T11:00:00Z
+---
+
+A new GA release for the Linux WARP client is now available on the [Stable release downloads page](/cloudflare-one/connections/connect-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 Address or domains](/cloudflare-one/connections/connect-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](/cloudflare-one/connections/connect-devices/warp/deployment/firewall/#connectivity-check). 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.
