Tailscale v1.66.4
Fixed UDP connectivity through Mullvad exit nodes. Disabled stateful filtering by default on Linux to restore DNS resolution from containers, while maintaining security mitigations for most setups.
- Fixed: Restored UDP connectivity through Mullvad exit nodes.
- Changed: Stateful filtering is now off by default. Stateful filtering was introduced in 1.66.0 as a mitigation for a vulnerability described in TS-2024-005, and inadvertently broke DNS resolution from containers running on the host. Most vulnerable setups are protected by other mitigations already, except when
autogroup:danger-allis used in ACLs.

Tailscale v1.104.1 — Performance and Features Release
Tailscale v1.104.1 delivers significant performance improvements including reduced WireGuard memory usage, client-side netmap caching for offline resilience, and enhanced features like device pinning, improved Taildrop support, and platform-specific fixes across all supported devices.
Declarative node sharing
Tailnet admins can now use policy to securely share resources between trusted tailnets in a declarative way, enabling controlled cross-tailnet access.
Linux client reconnection stability fix
Fixed an issue where the Linux client would stop tailscaled when falling behind on status updates. The client now reconnects instead of exiting, and only terminates if it cannot reconnect within one minute.
