+releaseNotes: |-
+  This release contains minor fixes, improvements, and new features including [Path Maximum Transmission Unit Discovery (PMTUD)](/cloudflare-one/team-and-resources/devices/warp/deployment/mdm-deployment/path-mtu-discovery/#enable-path-mtu-discovery). When PMTUD is enabled, the client will dynamically adjust packet sizing to optimize connection performance. There is also a new connection status message in the GUI to inform users that the local network connection may be unstable. This will make it easier to diagnose connectivity issues.
+
+  WARP client version 2025.8.779.0 introduced 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**
+  - The GUI now displays the health of the tunnel and DNS connections by showing a connection status message when the network may be unstable. This will make it easier to diagnose connectivity issues.
+  - Fixed an issue where deleting a registration was erroneously reported as having failed.
+  - Path Maximum Transmission Unit Discovery (PMTUD) may now be used to discover the effective MTU of the connection. This allows the WARP client to improve connectivity optimized for each network. PMTUD is disabled by default. To enable it, refer to the [PMTUD documentation](/cloudflare-one/team-and-resources/devices/warp/deployment/mdm-deployment/path-mtu-discovery/#enable-path-mtu-discovery).

+
+  **Changes and improvements**
+  - Fixed an inconsistency with [Global WARP override](/cloudflare-one/team-and-resources/devices/warp/configure-warp/warp-settings/#global-warp-override) settings in multi-user environments when switching between users.
+  - The GUI now displays the health of the tunnel and DNS connections by showing a connection status message when the network may be unstable. This will make it easier to diagnose connectivity issues.

+  - Improvements for the [OS version](/cloudflare-one/reusable-components/posture-checks/warp-client-checks/os-version/) WARP client check. Windows Updated Build Revision (UBR) numbers can now be checked by the client to ensure devices have required security patches and features installed.
+  - The WARP client now supports Windows 11 ARM-based machines. For information on known limitations, refer to the [Known limitations page](/cloudflare-one/team-and-resources/devices/warp/troubleshooting/known-limitations/#warp-disconnected-on-windows-arm).
+
+  **Known issues**
+  - For Windows 11 24H2 users, Microsoft has confirmed a regression that may lead to performance issues like mouse lag, audio cracking, or other slowdowns. Cloudflare recommends users experiencing these issues upgrade to a minimum [Windows 11 24H2 KB5062553](https://support.microsoft.com/en-us/topic/july-8-2025-kb5062553-os-build-26100-4652-523e69cb-051b-43c6-8376-6a76d6caeefd) or higher for resolution.
+
+  - 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).
+
+  - Devices with KB5055523 installed may receive a warning about `Win32/ClickFix.ABA` being present in the installer. To resolve this false positive, update Microsoft Security Intelligence to [version 1.429.19.0](https://www.microsoft.com/en-us/wdsi/definitions/antimalware-definition-release-notes?requestVersion=1.429.19.0) or later.
+
+  - DNS resolution may be broken when the following conditions are all true:
+    - WARP is in Secure Web Gateway without DNS filtering (tunnel-only) mode.
+    - A custom DNS server address is configured on the primary network adapter.
+    - The custom DNS server address on the primary network adapter is changed while WARP is connected.
+
+    To work around this issue, reconnect the WARP client by toggling off and back on.
