 # Changelog
 
+## [0.9.1.1] - 2026-03-20

+### Fixed
+
+- **gstack now works on Windows 11.** Setup no longer hangs, and the browse server automatically falls back to Node.js to work around a Bun pipe-handling bug on Windows. Just make sure Node.js is installed alongside Bun. macOS and Linux are completely unaffected. (Thanks @sozairali — PR #194)

+**Windows users:** gstack works on Windows 11 via Git Bash or WSL. Node.js is required in addition to Bun — Bun has a known bug with Playwright's pipe transport on Windows ([bun#4253](https://github.com/oven-sh/bun/issues/4253)). The browse server automatically falls back to Node.js. Make sure both `bun` and `node` are on your PATH.
