BrowserOS: baixar versions anteriors

✨ What's new
- No BrowserOS account needed. Sign-in and cloud-sync screens have been removed. Conversations continue to stay on your device, and sidebar history is now available to everyone.
- Connect your preferred AI. The built-in BrowserOS model has been retired. Connect an LLM provider or a coding agent in AI Settings to chat. If a scheduled task used the built-in model, choose a connected provider for it too.
- An updated model picker. The ChatGPT subscription model list now includes newer model families, and the provider catalogue has been refreshed. You can also enter a model ID directly; availability depends on your provider and subscription.
- Screenshots reach custom providers. Fixed an issue that prevented vision-capable models on OpenRouter and other OpenAI-compatible providers from receiving the agent's screenshots.
- Chromium 155. Updated to Chromium 155.0.8059.26.

✨ What's new
- A simpler BrowserOS agent. We've redesigned the agent experience to make it easier to use, with a cleaner interface and more straightforward setup. Your conversation now follows you across the tabs the agent works in.
- Better support for your AI provider. Improved compatibility across supported providers, including OpenAI, Anthropic, Google, and OpenRouter. Model selection and reasoning settings now better reflect what each model supports, with clearer error messages when something goes wrong.
- A much lighter agent extension. We cut the unpacked extension size by 86%, from 42.93 MB to 6.02 MB, so there's much less for the browser to unpack at startup.
- Chromium 151. Updated to Chromium 151.0.7922.137, bringing upstream security fixes and browser improvements.
Also changed: Voice input has been removed in this release.

✨ What's new:
- Auto-updates on Windows 🎉 — Long pending, finally here! BrowserOS now updates itself on Windows, just like on macOS. No more downloading and manually installing every release
- Fixed the recurring Windows pop-up — Squashed the bug where a dialog kept popping up every ~15 minutes on Windows, and improved its reliability overall. Please let us know if you still see it!
- Third-party agent integrations — Fixed a bunch of bugs and issues with agent integrations like Codex and Claude Code — connecting and staying connected is now much more reliable.

✨ What's new:
- Run Claude Code & Codex right in your browser — We've extended the agent harness to bring full coding agents into BrowserOS. Claude Code and Codex now come bundled and plug straight into the assistant, so you can drive your browser with the agent — and the subscription — you already use.
- A brand new experience — A redesigned new tab, a calmer composer, and a rebuilt command center for switching between agents. The whole assistant is cleaner, faster to reach, and easier to live in.
- New MCP tools — We rebuilt the browser tool surface from the ground up — a tighter, more reliable set of tools for agents to drive the browser. Plus one-click install of BrowserOS as an MCP server into the agents you already run, with automatic URL sync.
- Chromium 148 — Updated to the latest Chromium base with all recent upstream fixes and security patches.
- Streamlined — We've pulled back a few features that weren't getting much use — Skills, Soul, and Memory — so we can focus and ship better versions of them soon.

✨ What's new:
ChatGPT Pro & GitHub Copilot — Already paying for ChatGPT Pro, Plus, or GitHub Copilot? Now you can use that subscription to automate browser tasks in BrowserOS — at no extra cost. Just log in with your existing account.
Voice Input — Talk to your agent instead of typing. The chat bar now accepts voice input for any query.
Smarter Agent — Overhauled agent grounding for more reliable and precise browser actions.
Bug Fixes & Reliability — Improved memory tools, fixed fill tool issues, new tab layout fixes, and numerous stability improvements across the board.

✨ What's new:
Skills — Define reusable instructions that teach your agent how to handle specific tasks. Ships with 12 built-in skills like deep research, price comparison, and form filling — and you can create your own. Docs →
Memory — Your assistant now remembers you across conversations. Core memory stores permanent facts (your name, projects, preferences), while daily notes capture session context and auto-expire after 30 days. Everything stays local on your machine. Docs →
Kimi K2.5 — in partnership with Moonshot AI — Kimi K2.5 is now the default model in BrowserOS. Open-source, multimodal, and great for browser automation. For a limited time, users get extended usage limits at no cost. Bring your own key from platform.moonshot.ai anytime.
SOUL.md — Shape your assistant's personality, tone, and boundaries. It evolves on its own as you interact — the more you use it, the more it feels like yours. Docs →

✨ What's new:
- 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. Inspired by OpenClaw — thanks to @steipete for the great concept. Docs →
- 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. Docs →
- 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. Also inspired by OpenClaw. Docs →
- Chromium 146 — Updated to the latest Chromium release with all recent upstream fixes and security patches.

✨ What's new:
- New agent (v3) — Completely redone from scratch. 2x faster, 2–3x better performance.
- Tools — major upgrade — Agent tools and MCP server both got a big overhaul. ~20 new tools (54 total) including file upload, save as PDF, background windows, and more. Connection with third-party coding agents (Claude Code, Codex, etc.) is much better now.
- General fixes — Better agent installation, bug fixes, and smoother experience overall.
- Linux Debian packaging — Fixed the remaining Debian packaging issues.

✨ What's new:
- Chromium 145 — Upgraded to the latest Chromium base with all recent upstream fixes and security patches.
- Login session import improvements — Importing login sessions is now more reliable.
- Stability & reliability — General improvements across the board.

✨ What's new:
- Sync — Save your browser configuration, agent history, and scheduled tasks across machines. Your setup now follows you wherever you go.
- App Connector redesign — Connecting MCP apps is now easier. The new App Connector UI makes it simpler to discover, install, and manage your connected apps.
- MCP port stability — Additional fixes for users still experiencing port issues. More reliable connections across restarts.

✨ What's new:
- MCP port fix on Windows & Linux — Fixed an issue with MCP port. Port now stays consistent across restarts and made it more reliable.
- Settings fix — chrome://browseros/settings now works correctly.
- Improved agent — General reliability and performance improvements for the agent.

✨ What's new:
- Workflows — Build reliable, repeatable browser automations with a visual graph builder. Chat with the workflow agent to define step-by-step automation—ideal for complex tasks where ad-hoc prompts aren't enough. Read more →
- Workspaces — Give the agent access to a folder on your computer. Combine browser automation with local file operations—research on the web and save reports, scrape data and export to files, all in one task. The agent is sandboxed to your selected folder only. Read more →

🔧 Bug fix release
MCP server disconnect fix — Some users were experiencing MCP server disconnects during use. This release fixes the underlying port handling issue. If you've been seeing your MCP connections drop unexpectedly, please upgrade!
