What’s new at Stack Overflow: February 2026
This month, we’ve launched several improvements to AI Assist, opened Chat to all users on Stack Overflow, launched custom badges across the network, and launched one of the first community-authored coding challenges.
Welcome to the February recap of what’s new on stackoverflow.com. This month, we’ve launched several improvements to AI Assist, opened Chat to all users on Stack Overflow, launched custom badges across the network, and launched one of the first community-authored coding challenges. We’re also taking the opportunity to spotlight a community member in this month’s recap. Come check it out!
Since AI Assist became available on Stack Overflow in December 2025, we’ve added several updates and improvements to the AI-powered, conversational search and discovery tool. Some notable updates:
- Responses load much faster with optimized search and re-ranker services.
- Users can share conversations and re-share any updates with a new URL.
- When submitting code as part of a question, AI Assist now displays it in markdown format for better readability where possible.
- Added a link to the Stack Overflow MCP server documentation
Learn more about all the upgrades we’ve shipped, or give it a try. AI Assist is available to all users and can help you find reusable code, interpret error messages, resolve merge conflicts, and more!
New in 2026, we are thrilled to open all public chat rooms on Stack Overflow and Stack Exchange to registered users. Previously, participating in public chat rooms required 20 reputation points. As the platform integrates more features for community conversations alongside the traditional knowledge repository, chat offers an easy way to engage with the community and learn more about how to use Stack Overflow from day one.
Users can now chat in a myriad of technical chat rooms ranging from coding languages like Python, C#, and JavaScript or dig in deeper into all things Stack Overflow in The Meta Room. Hop over to Stack Exchange to chat about Mathematics or converse on your cuisine topics in The Frying Pan. Check out what the community is talking about and get chatting!
As part of the latest Community Ask Sprint, the community can now request custom badges for Stack Overflow and Stack Exchange sites. Communities can use these badges to recognize members who go above and beyond in various ways and reward users for actions and contributions that align with a site's activities and culture.
Do you have an interesting idea for a new Community Badge? Check your favorite site’s Meta and propose it as a new question! We can’t wait to see the unique recognition awarded to each community.
Thanks to M– (learn more about them below!), we have our latest community-authored challenge you can participate in.
Picture this: you’ve intercepted pieces of a dictionary from an unknown civilization, but you don’t know what order their letters go in.
The task: figure out the alphabetical order of all the symbols used in this language.
Start solving the puzzle now, chat with other users about their strategy and approach to this challenge, or head to the challenges Sandbox to put forward your own idea for a future challenge!
Meet M--!

SaaS Pricing Models Decoded: What Per-Seat, Usage-Based, and Flat-Rate Really Cost You
<p>Most SaaS buyers evaluate software on features and price. Fewer take the time to evaluate the pricing model itself, the structure that determines how much they will actually pay as usage grows, headcount changes, or the business's needs evolve. That oversight can turn a tool that looks affordable at ten users into a significant line item at fifty.</p> <p>Understanding the major SaaS pricing models is not just useful for the initial buying decision. It matters whenever a tool is up for renewal, whenever headcount shifts, or whenever a vendor introduces a price change. Knowing the model means knowing where your costs are exposed.</p> <p><strong>The Four Main Models and What They Mean in Practice</strong></p> <p><strong>Per-Seat Pricing</strong><br> Per-seat pricing charges a fixed monthly
I Built a macOS Terminal That Detects Your AI Coding Agents — Here's Why
<p>I've been writing Swift since 2015 and building macOS apps for most of my career. I always wanted to build a terminal — not because the world needed another one, but because a terminal emulator touches everything I find interesting: low-level input handling, GPU rendering, process management, and shell integration.</p> <p>For years, it stayed on my someday list. Then two things happened at the same time.</p> <p>In late 2024, <a href="https://ghostty.org" rel="noopener noreferrer">Ghostty</a> launched and open-sourced <strong>libghostty</strong> — a production-grade terminal rendering engine built on Metal. Suddenly, I didn't need to write a GPU renderer from scratch. The hardest part of building a terminal was solved.</p> <p>Around the same time, AI coding agents went from novelty to da

How to Use the ES2026 Temporal API in Node.js REST APIs (2026 Guide)
<p>After 9 years in development and countless TC39 meetings, the JavaScript Temporal API officially reached <strong>Stage 4 on March 11, 2026</strong>, locking it into the ES2026 specification. That means it's no longer a proposal — it's the future of date and time handling in JavaScript, and you should start using it in your Node.js APIs today.</p> <p>If you've ever shipped a date-related bug in production — DST edge cases, wrong timezone conversions, silent mutation bugs from <code>Date.setDate()</code> — you're not alone. The <code>Date</code> object was designed in 1995, copied from Java, and has been causing developer pain ever since. Temporal is the fix.</p> <p>This guide covers <strong>how to use the ES2026 Temporal API in Node.js REST APIs</strong> with practical, real-world patter

Axios Hijack Post-Mortem: How to Audit, Pin, and Automate a Defense
<p>On March 31, 2026, the <code>axios</code> npm package was compromised via a hijacked maintainer account. Two versions, <code>1.14.1</code> and <code>0.30.4</code>, were weaponised with a malicious phantom dependency called <code>plain-crypto-js</code>. It functions as a Remote Access Trojan (RAT) that executes during the <code>postinstall</code> phase and silently exfiltrates environment variables: AWS keys, GitHub tokens, database credentials, and anything present in your <code>.env</code> at install time.</p> <p>The attack window was approximately 3 hours (00:21 to 03:29 UTC) before the packages were unpublished. A single CI run during that window is sufficient exposure.<br> This post documents the forensic audit and remediation steps performed on a Next.js production stack immediatel
