v1.66.4

All platforms

• Fixed: Restored UDP connectivity through Mullvad exit nodes.

Linux

• 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-all is used in ACLs.

v1.66.3

All platforms

• Fixed: Login URLs did not always appear in the console when running tailscale up.

Android

• Changed: Reintroduced the Quick Settings title that v1.66.0 temporarily removed.
• Changed: Improved the VPN service connection logic, especially when rebooting the device with Always-On VPN enabled.
• Changed: The persistent VPN status notification now informs the user with a muted icon when the VPN is disconnected. VPN status notifications can be disabled in the system notification settings.
• Fixed: The "Enable" button in the exit node selector banner now renders with the correct background color.

Kubernetes operator

• Breaking change: Starting with v1.66, the Kubernetes operator must always run the same or later version as the proxies it manages.
• New: Expose cloud services on cluster network to the tailnet, using Kubernetes ExternalName Services. This allows exposing cloud services, such as RDS instances, to tailnet by their DNS names.
• New: Expose tailnet services that use Tailscale HTTPS to cluster workloads. Refer to #11019.
• New: Cluster workloads can now refer to Tailscale Ingress resources by their MagicDNS names. Refer to #11019.
• New: Configure environment variables for Tailscale Kubernetes operator proxies using ProxyClass CRD.
  Refer to ProxyClass API.
• New: Expose tailscaled metrics endpoint for Tailscale Kubernetes operator proxies through ProxyClass CRD. Note that the tailscaled metrics are unstable and will likely change in the future. Refer to ProxyClass API.
• New: Configure labels for the Kubernetes operator Pods with Helm chart values. Refer to Helm chart values.
• New: Configure affinity rules for Kubernetes operator proxy Pods with ProxyClass. Refer to ProxyClass API.
• Fixed: Kubernetes operator proxy init container no longer attempts to enable IPv6 forwarding on systems that don't have IPv6 module loaded. Refer to #11867.

Containers

• Fixed: Tailscale containers running on Kubernetes no longer error if an empty Kubernetes Secret is pre-created for the tailscaled state. Refer to #11326.
• Fixed: Improved the ambiguous error messages when Tailscale running on Kubernetes does not have the right permissions to perform actions against the tailscaled state Secret. Refer to #11326.

v1.66.2

An internal release which was not distributed

v1.66.1

This release is exclusively for Linux platforms and the standalone variant of the macOS client. It is not available for other platforms.

Linux

• tailscale set command flags --netfilter-mode, --snat-subnet-routes, and --stateful-filtering are added.
• Resolved issues with nftables rules for stateful filtering, introduced in v1.66.0.

macOS

• A version mismatch warning no longer displays when upgrading, if no mismatch is detected.

v1.66.0

We recommend updating all Tailscale clients to v1.66.0 or later to benefit from additional security improvements.

All platforms

• Implemented client-side quarantining for shared-in exit nodes, as a mitigation for a security vulnerability described in TS-2024-005.

Linux

• Use the --stateful-filtering flag for the tailscale up to enable stateful filtering for subnet routers and exit nodes, as a mitigation for a security vulnerability described in TS-2024-005.
  • Note: This change can break existing setups that depend on forwarding connections from external hosts (internet, LAN, Docker containers, etc.) into the tailnet through a Tailscale node. If your setup depends on such forwarding, you can disable stateful filtering with the tailscale up --stateful-filtering=false command.
• Use tab completion to type the first few letters of a Tailscale CLI command, flag, or arguments, followed by the tab key to complete the item being typed. Set up tab completion by using the tailscale completion command.
• Use the tailscale exit-node suggest command to automatically pick an available exit node that is likely to perform best.
• Site-to-site networking now also requires --stateful-filtering=false in addition to --snat-subnet-routes=false on new subnet routers. Existing subnet routers with --snat-subnet-routes=false will default to --stateful-filtering=false.

macOS

• View a suggested exit node in the Exit Node picker when available.
• Generate a macOS Configuration Report .txt file from the Bug Report view to help the Tailscale support team diagnose issues.
• Improved error detection logic warns the user when a version mismatch is detected between the Tailscale client GUI and the network extension.

• Improved UI experience to log into a custom coordination server like Headscale.
• The Fast User Switching view can now be used when Tailscale is disconnected.
• Improved error detection logic warns the user when a version mismatch is detected between the Tailscale client GUI and the network extension.
• Reduced app launch time.

tvOS

• Use new status indicators to see at-a-glance insights into node connectivity. Tap on a node to see detailed information.
• See detailed information about resolvers, domains, and routing configurations in a dedicated DNS Settings view.
• See the status of Tailnet lock and node keys.
• Use Fast user switching to switch between two or more logged-in accounts on the same device, without requiring you to re-authenticate.
• Use auth keys to log in without using the browser.
• Manage Android devices in your tailnet using Mobile Device Management (MDM) solutions such as Google Workspace, Microsoft Intune, or TinyMDM, among other tools.
