# September Tailscale newsletter

A new month, a new set of updates! The team has been busy building new features, including HTTPS certificate support and GitHub Marketplace integration. We also launched [free pricing for open source GitHub orgs](/content/blog/community-github-pricing/index.html). Community members shared [CircleCI integrations](https://blog.threecomma.io/circleci-meet-tailscale), [a custom DERP Docker image](https://github.com/fredliang44/derper-docker), and more. Let’s dive in!

**Windows admins:** to maintain connectivity, please upgrade to Tailscale 1.14.4 or later before updating Windows. [Read how and why the upgrade is needed.](/content/blog/windows-updates/index.html)

- [**Action required: Upgrade Tailscale to 1.14.4+ prior to updating Windows**](/content/blog/windows-updates/index.html)

For Windows admins, to maintain connectivity, please upgrade to Tailscale 1.14.4 or later before updating Windows.

### New features

**Tailscale + Let’s Encrypt**

Tailscale now makes HTTPS easily available for the machines in your Tailscale network, also known as a tailnet, with certificates provisioned from Let’s Encrypt. Connections were already encrypted by Tailscale, but this lets you get rid of the ugly “insecure” warning displayed by web browsers.

**Tailscale + GitHub Actions**

Our GitHub Action is now available [in the marketplace](https://github.com/marketplace/actions/connect-tailscale)! This means that with the Connect Tailscale action, you can easily pull ‘Connect Tailscale’ into whatever actions you write. Use this to securely deploy your application to internal servers, reach your private test runners for specific platforms, or connect to your database of test data without leaving it exposed on the Internet.

**Tailscale 1.16 coming soon**

We will be releasing Tailscale 1.16 in the coming week — look for Taildrop support on older versions of Android, among other fixes and general improvements.
