[dependabot]

Bumps tailscale.com from 1.66.3 to 1.68.2.

Release notes

Sourced from tailscale.com's releases.

v1.68.2

All Platforms

• Fixed: Tailnet lock validation of rotation signatures now permits multiple nodes signed by the same pre-signed reusable auth key.

macOS, iOS

• Changed: Wake from sleep reliability is improved for re-connections and transitions between networks.

v1.68.1

All Platforms

• Fixed: 4via6 subnet router advertisement works as expected.

Linux

• Fixed: Tailscale SSH access to Security-Enhanced Linux (SELinux) machines works as expected.

v1.68.0

All Platforms

• Changed: Build Tailscale with Go 1.22.4
• New: Auto-updates are allowed in containers, but ignore the tailnet-wide default
• New: Apply auto-updates even if the node is down or disconnected from the coordination server.
• New: tailscale lock status now prints the node's signature.

Windows

• Changed: The exe installer no longer has the ability to automatically download MSI packages for Windows 7 and Windows 8. See the v1.42.0 changelog for our initial end of life annoucement.

macOS

• New: The Standalone variant of Tailscale can now install the Tailscale CLI in /usr/local/bin for quicker and easier access.
• New: Tailscale now detects any attempt to use DHCP Option 121 to misroute traffic meant for the VPN (TunnelVision attack), and presents a warning to the user. System administrators can disable this warning with a system policy.
• New: The Standalone variant of the client now supports notifications when a file is received using Taildrop.
• Changed: Tailscale now starts more reliably if another VPN app was running when Tailscale was enabled.
• Changed: The .pkg installer now terminates Tailscale and the VPN extension before proceeding with the installation.
• Fixed: Tailscale now properly detects any copy of TunnelBear installed on the Mac, and warns the user about incompatibility.
• Fixed: Resolved an issue that could have caused “Using Exit Node” to incorrectly appear in the app menu before completing onboarding, upon first app launch.

iOS

• Changed: Battery life is optimized by offloading DNS resolution to iOS in more cases.
• Changed: Tailscale now starts more reliably if another VPN app was running when Tailscale was enabled.
• Fixed: Opening the bug report view no longer copies the bug report ID to the Clipboard automatically.
• Fixed: The Reauthenticate button within in-app key expiry notifications now works properly.
• Fixed: Minor tweaks to UI colors when dark mode is enabled.
