This has been a busy month, with the launch of Tailscale v1.8 and a new feature, Taildrop, that lets you easily send files between your devices. Here’s a quick preview before we jump into this month’s update:

Tailscale v1.8

General Fixes and Improvements

We’ve added a long-awaited tailscale logout command. We also now allow clients access to an exit node’s public IPs.

The tailscale up command now warns when options are being changed by omission. For example, if you used tailscale up --advertise-route= and then tailscale up --advertise-exit-node, it would notice and warn that the advertise-route would be removed.

🐛 We added the tailscale bugreport command to add a marker in your logs, along with an optional note. If you run it shortly after a problem occurs (or ideally both before and after reproducing a problem) it will make it easier for support@tailscale.com to find the details in your logs. Note that you still need to send an email or file a bug: the bugreport only adds a known point in the logs so we can work with you to solve it more efficiently.

There was a large effort to improve and address DNS configuration issues and MagicDNS across all platforms. This leads nicely into our work on another new feature…

Split DNS

Split DNS lets you set a DNS server that is only used for specific domain names — something users with complicated DNS configs have been asking for. Split DNS enables better control over where DNS requests go, and allows you to apply more advanced policies. For example, you could route DNS queries for your AWS VPC to one server, and queries for your Azure private network to another one, without interfering with regular DNS on your LAN.

Split DNS is complementary to MagicDNS. You can create split DNS configs with and without MagicDNS, and this is now generally available to everyone.

Admin Console Updates

The admin UI now has a new “Settings” panel, including a page for “feature previews” letting admins to easily toggle features on and off. Use this page to opt your network into new Tailscale features.

Taildrop (alpha)

Taildrop makes it easy to send files between your personal devices on a Tailscale network. Like all traffic sent over Tailscale, Taildrop transfers files over encrypted peer-to-peer connections, using the fastest available path. This makes it a great solution for sending sensitive or large files without third-party servers in the middle.

📢 This feature is in public alpha, with many planned improvements to the UX and capabilities. To try Taildrop today, you’ll need to opt-in for your network and use Tailscale v1.8 or later.

You can transfer any kind of files with Taildrop. Taildrop is currently limited to sending files between your own personal devices. You cannot send files to devices owned by other users even on the same Tailscale network.

To send a file with Taildrop:

  • macOS: Right-click on any file and go to “Share → Tailscale.” The first time you use Taildrop, it might be hidden in the “More…” section.
  • iOS: Open a photo and tap the Share menu. Choose Tailscale and tap the device you’d like to send files to. The first time you use Taildrop, it might be hidden in the “More…” section of the menu.
  • Windows: Right-click on any file and choose “Send with Tailscale…”
  • Linux: Use the tailscale file subcommand to choose which files to send. For example, to send a text file to your phone:tailscale file cp ./my-file.txt my-phone:
  • Android: Coming soon!
