The new @code release supports BYOK without a GitHub sign-in, making it easier to use your own language models or run workflows using local models like Ollama. Check out what’s new:

TypeScript developers, rejoice! Every atproto package now ships as ESM, which means our build tooling is modernized and ready for the faster TypeScript 7. Don't forget to check out the stabilized lex SDK while you're here. atproto.com/blog/ts-sdk-...

you can just complain about things

The new @code release adds Mermaid diagram rendering directly in the Markdown preview. The Integrated Browser also now supports HTML file previews and drag-to-select for pulling multiple page elements into chat context.

Let's help the TypeScript team test the TS 7.0 beta! 🤍

You can try it out on your project by installing our native-preview package from npm. New releases are published daily, and are already used by many teams in production! npmx.dev/package/@typ...

Something subtle from @vscode.dev's recent release notes: VS Code core, and all its built-in extensions, are now type-checked with TypeScript 7 native previews! code.visualstudio.com/updates/v1_1...

Axel is perhaps the most professional and diligent JS educating author. I remember when it felt like a new JS feature wasn't "done" until he had written the corresponding explainer article. You can thank him by buying his books 📚

🪄 Your agent experience, refined. The latest VS Code release brings better BYOK visibility and control, integrated browser improvements, and more. It also introduces the new Agents window (preview), making it easier to explore, iterate on, and review tasks across multiple projects.

here is the new CSS Border shape API this is going to unlock so many sick new designs

🚀 Better prompts. Smarter agents. More control. The latest @code release introduces the Chat Customizations Evaluation extension, designed to help analyze and refine your prompts, agents, instructions, and skills.

My TypeScript 7.0 results for a React Native app: TS 5.9.3 => 4.459 s ± 0.073 s TS 6.0.3 => 4.248 s ± 0.066 s TS 7.0-beta => 747.6 ms ± 9.6 ms

On the @sentry.io codebase: - tsc is 56s - tsgo is 9s Use it, NOW 🔥

A massive congratulations to the @typescriptlang.org team on this release! We love to see it 🎉 Looking forward to migrating my projects over to 7.0 in the coming months!

TypeScript 7.0 Beta is out 🎉 It's the 10x faster Go-based port 🔥 🔷 `tsgo` vs `tsc` CLIs allow comparing 🔷 --checkers sets checker thread count 🔷 --singleThreaded keeps parsing/emit/checking together 🔷 TS 6.0 deprecations are hard errors 🔷 API access is planned for TS 7.1

TypeScript 7.0 Beta is here! Built on a new native and parallelized foundation, it's already being used on multi-million line codebases. Read up more here and try it on your projects today! devblogs.microsoft.com/typescript/a...

Thread: How I accidently DDoS'd npm with TypeScript

Next episode of e18e & friends, we will be talking to @jakebailey.dev ! Come join us on April 28th at 1PM EST / 7PM CET 🎉

An internal team just adopted tsgo (soon TypeScript 7) and told us they were able to shave off about 400 hours a month of waiting on CI builds. npmx.dev/package/@typ...

New VS Code release today 🚀 We're enhancing the agent experience with debug logs for past sessions, terminal interaction tools, built-in GitHub Copilot, and more!

> fs.globSync("src/**/*.ts").length 838 > fs.globSync("src/**/*.{ts,tsx}").length 1001 > fs.globSync("src/**/*.{ts}").length 0 > fs.globSync("src/**/*.{ts,}").length 838 🤨

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
