2025 was our biggest year yet. 3 major releases. Over 250 new features, improvements and fixes. Stack layout. Frames. Automatic concentric corners. Progressive blurs. Glass. A major redesign. MCP server. And so much more.

Our next major update is here — and it’s got glass in it.

Yep, that glass. Non-solid, lowercase-G glass. It works right out of the box (as all glass should?) but you can also tweak every parameter. It’s a lot of fun.

And that’s not all! ↓

Remember when we said auto layout was coming to Sketch? It’s here. It’s called Stacks, and it’s part of our biggest release ever — out now.

There’s a lot to cover, so buckle up and we’ll take you on a tour.

Also, stick around for a surprise at the end of the thread. 👀

Let’s go ↓

"[FD] ChatGPT AI finds "security concern" (XSS) in DeepSeek's code"

What a massive, misleading clickbait title.

However, it's scary to think that such vulnerabilities are present when AI tools generate code. Dangerous times are ahead when developers use those code suggestions blindly.

We’re working a stack layout feature for @sketch.com, and while we still have lots to do, here’s a sneak peek from yours truly: youtu.be/wK_OXZxakPQ

Particularly pleased with how we’ve repurposed the existing alignment actions to override cross-axis alignment on items.

Please don’t 🙈
Security pro tip: if you find a USB key on the ground somewhere, DO NOT plug it in to your home computer.

Take it to the office and plug it in there. They have way better software that will mitigate any threats.
