## v0.42.0
<sub>March 9, 2026</sub>

- **SOUL.md** — Your assistant now has a soul. Tell it how you like to communicate, set boundaries, shape its personality — and it adapts on its own over time. The more you use it, the more it feels like *your* assistant. [Read more →](/features/soul)
- **Vertical tabs** — One of the most requested features is here. BrowserOS now ships with vertical tabs by default. More screen space, better tab management, and a cleaner layout out of the box. Prefer horizontal? You can switch back anytime in settings. [Read more →](/features/vertical-tabs)
- **Long-term memory** — Your assistant finally remembers you. Your name, your projects, what you talked about last week — it carries context across every conversation so you never have to repeat yourself. All stored locally on your machine. [Read more →](/features/memory)
- **Chromium 146** — Updated to the latest Chromium release with all recent upstream fixes and security patches
