- C++23 is now feature-complete in IntelliSense (modules still pending); the GitHub Copilot September update adds a one-click NuGet vulnerability fixer.
What happened?
Microsoft's October 2026 feature update for its flagship IDE landed as Visual Studio 2026 version 18.11.0 on 20 October 2026, and a small servicing release, 18.11.1, followed a day later on 21 October. This is a current-channel update: new productivity features in 18.11.0, bug fixes in 18.11.1. Microsoft's own Visual Studio Blog marked the occasion on 21 October with a post dedicated to the headline feature — Compare with Working Tree — which, it says, came directly from a community request.
The GitHub Copilot team landed its September update for Copilot in Visual Studio on 22 October, which sits neatly on top of the 18.11 release: NuGet Audit warnings in the Error List now carry a fixer action that opens Copilot Chat in agent mode and asks it to fix the vulnerable package via the NuGet MCP server. That fix path works on every Copilot plan, including the free one.
What's new in Visual Studio 2026 18.11? Features explained
| Feature | What it does | Where it came from |
|---|---|---|
| Compare with Working Tree | Right-click any commit in the Git Repository window and compare it against your current uncommitted changes. The commit becomes the baseline; VS lists every file that differs — not just files the commit touched. | Community request, 18.11.0 |
| Move active tab | Ctrl+Shift+PgUp / PgDn reorders the active tab left/right (up/down with vertical tabs) without switching focus. Works for tool windows docked in the document well too. | 18.11.0 |
| Jump to tab by position | Ctrl+NumPad1–9 activates the matching visible document tab. One caveat: it takes over a shortcut combo some editors already use, so check your keybindings. | 18.11.0 |
| C++23 in IntelliSense | C++23 is now feature-complete in IntelliSense — except modules, which are still pending. Honest progress, not the full line. | 18.11.1 |
| Copilot NuGet fixer | NuGet Audit warnings in the Error List get a fixer action: Copilot Chat in agent mode proposes and applies the vulnerable-package fix. | Copilot September update |

Why it matters for developers
The 18.11 release is a small but telling one. Compare with Working Tree answers one of the most common Git-workflow frustrations in an IDE: "I know this worked three commits ago — what changed since then, including the code I haven't committed yet?" Until now, answering that meant stashing, checking out, or leaning on command-line plumbing. Baking it into the repository-level commit workflow keeps the whole loop inside one window, which is exactly the kind of friction removal that compounds across a team day.
The tab shortcuts look minor, but developers live in tab triads — implementation, test, interface — and keyboard-only arrangement plus positional jumps is the kind of muscle-memory upgrade heavy VS users notice within a day. And the Copilot NuGet fixer turns a security warning into a one-click agent-driven fix, which pairs naturally with this week's broader python 3.15.1 security update how to upgrade push: patch your toolchains, patch your IDE, patch your dependencies.
For developers watching the agent-IDE wave, this update is part of a pattern across October's releases — the same week brought the bun 1.4.4 release new features security update explained story and the open-source AI stack around google torchtpu open source pytorch on tpu explained. IDEs and runtimes are both being rebuilt around agentic workflows this month.
Should you update now? ✅
Yes — it's a low-risk, genuine-improvement update. 18.11.1 already contains the first round of bug fixes (including the compose-project debugging fix and the Windows SDK 10.0.26100.9457 installer update), so skipping straight to 18.11.1 is the cleanest path. The new tab shortcuts deserve a five-minute keybinding review if you customised Ctrl+NumPad combos. C++ shops should note the modules exception in the C++23 story before declaring compliance. The verdict: ✅ update — real workflow wins, no risky plumbing changes.
Availability and alternatives
Visual Studio 2026 18.11.1 is available now through the Visual Studio Installer — run a check for updates, or download the latest installer if you're on an older minor. Community, Professional and Enterprise editions all get the feature update. The NuGet Copilot fixer arrives via the GitHub Copilot in Visual Studio September update, on all plans including Copilot Free.
Alternatives if you don't use Visual Studio: VS Code gets the same Copilot agent-mode trajectory through extensions, and the October update wave has touched most of the ecosystem — Node, TypeScript, Python and Bun all shipped this month too.
