📝 Work on Markdown files and agent feedback in one place. The new hybrid Markdown editor in the Agents window lets you edit in place, add comments for the agent to act on, and switch views with Reopen Editor With when needed.

🚀 See what your subagents are doing in real time, use built-in dictation across VS Code, and streamline docs with the hybrid Markdown editor. 🧵 Here's what's new in the latest VS Code release:

Below the logo, large white text reads “VS Code v1.131,” with smaller text underneath that says “New release.” The design uses a minimalist, high-contrast layout with Microsoft branding colors.

Soo I hit the button to release TS 7 then swiftly went out of office for vacation 😅 How's it going for everyone? Hopefully speedy speedy good

Thanks to lots of work preparing and tracking the preview builds for most of the year 2026… Vanta’s upgrade to #TypeScript v7 was basically trivial! I made one small change for a change (an improvement!) to inference that landed between our last nightly mid-June, and that was it. ✅ Feels good!

This is a really big deal. For us at Vanta, the speedup was a bit less than the highest values some teams have seen (3–5×), but let me tell you: 3–5× is still a very big deal for our CI times, and the improvement to editor performance is night and day.

The 10x is real for many projects, and the speed improvements make a huge difference for teams at scale. TypeScript 7 drops time in CI, and minimizes delays in editors like VS & VS Code. That makes every part of the developer inner loop feel snappy.

🚀 The latest VS Code release makes model tuning and chat cost tracking easier. Adjust context size and reasoning effort from one unified model customization picker. You can also see the total cost of every chat session, so it’s easier to understand usage over time.

Many people focus on the tsgo run itself, but the development experience is so much faster too! Just gotta remember to use the tsgo LSP. For example, when I want to find all the places when a function is being used, it’s so much faster. This makes a lot of difference.
