Hey, that's me! Come learn about TypeScript with us 😊 We'll have a fun announcement next week too with some very exciting prizes...

I also cannot ship my work today because it’s too powerful to release publicly

We've been shipping a lot with our VS Code weekly releases! 🚀 Here's a roundup of some of the highlights from the past month: 🤖 Autopilot 🌐 Integrated browser debugging 🎨 Refreshed themes … and much more! See what's new in our changelog: aka.ms/VSCode/Chang... Happy coding! 💙

Union types in C#! devblogs.microsoft.com/dotnet/cshar...

@code introduces message steering and queuing. You can now send follow-up messages while an agent request is still running.

We are THRILLED to announce that our Ecma standards will now use UUIDs instead of integers. ECMA-262 is now ECMA-39c506d7-731f-4220-8ffd-a68970945a65. Far more scalable. No two specs will ever collide again. Perfect system. Shortened forms like ECMA-39c506d7 are acceptable in casual conversation.

On Wednesdays, we ship! 🚀 This week’s VS Code highlights include the new Customization window: a central place to manage all chat customizations.

TypeScript 6.0 is out 🎉 🔶 Temporal 🔶 Map#getOrInsert 🔶 RegExp.escape 🔶 #/ prefix for Package Imports New defaults! 🔶 --target=ES2025 🔶 "use strict" 🔷 --strict Deprecations! 🗑️ baseUrl, outFile 🗑️ import assertions 🗑️ `module` namespaces 🗑️ module: amd 🗑️ moduleResolution: node 🗑️ target: ES5

aw yeah! default `strict: true` and `types: []` 🎉🎉 best defaults!

Six type scripts? In this economy?

TypeScript 6.0 is now available! This release brings better type-checking for methods, new standard library features, new module features for Node.js, and more! But most important, this release brings us one step closer to the upcoming native-speed 7.0! devblogs.microsoft.com/typescript/a...

Feeling mighty proud of the JIT team this morning. fidget-spinner.github.io/posts/jit-on...

🌐 Agentic Browser Tools (Experimental) in VS Code! Agents can now open pages, read content, click elements, and verify changes directly in the integrated browser while building your web app. Enable ⚙️ workbench.browser.enableChatTools to try it out. Learn mode: aka.ms/VSCode/Agent...

🤖 Try Autopilot (Preview) in VS Code! With Autopilot enabled, the agent stays in control of the workflow. It can run tools, retry on errors, and continue working until the task is complete. Learn more: aka.ms/VSCode/Autop...

ECMAScript Euphoria! 🎉 We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4. Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌

ECMAScript EXTRA-SPECIAL excitement 😉 🚨🚨🚨 IT'S ABOUT TIME! 🚨🚨🚨 Congrats to @ptomato.name on advancing Temporal to Stage 4 at @tc39.es today 🎉 Temporal is the replacement for the JavaScript Date API 👍

Temporal is now Stage 4 at TC39 🎂🎂🎂 Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years! I wrote a blog post explaining how we got here 📜 bloomberg.github.io/js-blog/post...

Source maps are a vital part of modern web development, but the lack of a standard made it impossible for us to add new features or improve the debugging experience. This is the story of how we standardized source maps and how we continue to ship features through standards 📜 🧵

Some time ago, @jonkuperman.com & @tchetwin.bsky.social had a dream for the JS engineers at Bloomberg to be more public about the cool JS work we have going on. That dream has come true - now we have a blog platform 🎉 (You'll see more articles over the next few days) bloomberg.github.io/js-blog/

Some other awesome stuff in these announcements: 🖼️ Kitty graphics terminal rendering (i.e. pictures in your console!) 🧬 Unified settings for JavaScript+TypeScript 🐍 Python Environments Extension is stable (works across env managers, includes uv integration) 🤫 Set eagerness for AI code completion

TypeScript 6.0 RC is out 🎉 🔶 Temporal 🔶 Map#getOrInsert 🔶 RegExp.escape 🔶 #/ prefix for Package Imports New defaults! 🔶 --target=ES2025 🔶 "use strict" 🔷 --strict Deprecations! 🗑️ baseUrl, outFile 🗑️ import assertions 🗑️ `module` namespaces 🗑️ module: amd 🗑️ moduleResolution: node 🗑️ target: ES5

The Release Candidate for TypeScript 6.0 is now available! Read up on what's coming up with 6.0 & 7.0, and try it out on your codebase today! devblogs.microsoft.com/typescript/a...

Agents, for real work. The latest VS Code release gives you better agent orchestration, extensibility, and continuity. Here's what's new: 🪝 Hooks support 🎯 Message steering and queueing 🌐 Agentic integrated browser 🧠 Shared memory And more... 🔎 Full release notes: aka.ms/VSCode/110

Next edit suggestions just leveled-up in VS Code: with long-distance NES, you get edit suggestions anywhere in your file, not just near your cursor's position. Learn how the team built this - creating the training dataset, refining the UX, evaluating success, and more: aka.ms/VSCode/long-...

🚀 Insiders Update - Feb 21-Feb 23 ✨ Redesigned chat model picker with recent models and search https://code.visualstudio.com/updates/v1_110 #vscode

The PostgreSQL team at Microsoft is hiring for a developer advocate, remote-friendly: https://apply.careers.microsoft.com/careers/job/1970393556753261 I've worked with that team a bunch, and it's a good group of intelligent and friendly people.

"tsgo caught type errors that the JavaScript implementation didn’t catch! I adopted tsgo in 20+ projects ranging from 1,000 to 1,000,000 lines of code, and it has improved iteration speed quite a bit." cpojer.net/posts/fastes...

console.log("Hello, World!"); Follow for updates on every new release of @vscode.dev!

Some pretty awesome improvements in 1.26 for compiling/testing typescript-go. With a clean build/test cache, running the full test suite used to take 3m45s, but now takes just 2m10s.

Our tsgo adoption at Vanta has been pretty high-impact. Everything is so, so much faster now.

"You know, I actually don't hate it anymore. It's actually pretty good." Glowing endorsements from my Python friends. 🥰

TypeScript excitement 😉 Congrats to @moriken.dev on landing support for the ES2025 target in upstream TypeScript 🎉 Heading for TS 6.0 Beta next week 👍 github.com/microsoft/Ty...

TypeScript excitement 😉 Congrats to Renegade334 on landing type declarations for @tc39.es Temporal - the new JS Date-Time API - in upstream TypeScript 🎉 Heading for TS 6.0 Beta next week 👍 Temporal is available in Firefox & Chrome today. github.com/microsoft/Ty...

By the way, TypeScript is finally strict by default 🎉

👀 TypeScript 6.0 (beta) drops next week It should be the last JS-based TSC version (no 6.1.*, only patches) TypeScript 6.0 is a “bridge release ” toward TypeScript 7.0, written in Go, ~10x faster github.com/microsoft/Ty...

You told us you’re running multiple AI agents and wanted a better UX. We listened and shipped it! Here’s what’s new: 🗂️ Unified agent sessions workspace for local, background, and cloud agents 🔀 Parallel subagents 💻 Claude and Codex support for local and cloud agents 🌐 Integrated browser & more...

TypeScript excitement 😉 Congrats to @jakebailey.dev on updating upstream tsc to default to an unpinned *latest* yearly edition of ES20xx. Heading for TS 6.0 🎉 This mean less transpilation of new JS features & more use of native language features provided by JS engines 👍 github.com/microsoft/Ty...

You may have noticed that search on the VS Code website has gotten a lot quicker lately. In our latest blogpost, João Moreno breaks down the engineering process behind docfind, a search engine we built that runs entirely in your browser using WebAssembly: code.visualstudio.com/blogs/2026/0...
