Tailscale v1.2 is here

The team has been hard at work making Tailscale more Tailscale-y. Today we’re announcing v1.2 is stable and ready for teams and hobbyists alike. Most notably, this release includes MagicDNS for everyone and major improvements for our Windows client.

How to update:

*For macOS and iOS, you may need to quit Tailscale first; the App Store doesn’t seem to update running VPN apps.

What happened to v1.1? (Or, a brief note on version numbers)

Eagle-eyed readers may notice that our last stable release was v1.0, and now here we are at v1.2. What happened to v1.1?

Since v1.0 we’ve begun using an alternating version numbering system. Stable releases use even numbers (1.0, 1.2, 1.4) and unstable releases use odd numbers (1.1, 1.3, 1.5). This format makes it easier to identify which build of Tailscale your devices are running, and can help with troubleshooting issues. For the adventurous, you can find our latest unstable version (v1.3) on our site.

What’s Included

A browser window showing a web server being accessed via “my-server:8185” rather than a Tailscale IP address.

MagicDNS, available on stable builds!

MagicDNS lets you access devices on your network via hostnames rather than having to remember IP addresses. For example, you could visit your monitoring webserver by going to monitoring/ in your browser, or SSH to your production servers with ssh username@www-prod-eu-west-1. Simple!

It works by running an embedded DNS server on your device at, serving names for nodes in your network. Requests for regular DNS names are forwarded to your upstream resolver.

MagicDNS is still in beta, and needs to be manually enabled from the admin console. We’re working on fixing several DNS bugs on less common operating systems and configurations before we remove the beta label. But with this release v1.2, MagicDNS is available for everyone to try.

Unattended Mode for Windows

Unattended Mode lets your Windows device be reachable over the network, even if no Windows user is logged in, like how Tailscale runs on Linux. This is particularly useful for connecting to Windows via RDP or VNC (as Tailscale runs in the background at boot) or running web, database, or other servers.

Unattended Mode can be enabled on Windows with the new “Run unattended” checkbox from the Tailscale tray icon’s context menu.

Admin Console Improvements

Outside of the Tailscale client, we’ve also introduced a number of improvements to our ACL editor, to help teams manage access controls for their network:

ACL Tests

Admins can now define automated tests to ensure specific users have (or don’t have) access to a given device/port. These tests can help ensure you don’t adversely affect your network when changing rules that involve multiple groups, tags, roles and rules. Learn more →

ACL Rule Preview

Another way to ensure your network rules behave as expected: ACL Rule Preview lets you preview which devices a particular user on your network can access. It also shows you which rules on which lines allow that access, so you can change or fix broken rules. Learn more →

As always, email us or tweet us (@tailscale) if you have any problems and we’ll try to help.
