+releaseNotes: |-
+  This release contains minor fixes, improvements, and new features including Path Maximum Transmission Unit Discovery (PMTUD). With PMTUD 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 debug 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 debug connectivity issues.
+  - Deleting registrations no longer returns an error when succeeding.
+  - Path Maximum Transmission Unit Discovery (PMTUD) is now used to discover the effective MTU of the connection. This allows the client to improve connection performance optimized for the current network.
+
+  **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](/cloudflare-one/connections/connect-devices/warp/configure-warp/route-traffic/local-domains/#route-traffic-to-fallback-server).

+  - macOS Sequoia: Due to changes Apple introduced in macOS 15.0.x, the WARP client may not behave as expected. Cloudflare recommends the use of macOS 15.4 or later.

+  **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 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.
