<Update label="February 27" tags={["Product", "Docs"]}>
  ## Product updates

  * We launched our new look! Our visual identity has been updated across our website, product, and docs.
  * **Important:** Persistent browser functionality will be end-of-life'd as of May 18th. If you're using this functionality, you've received an email from us with next steps. Please reach out for further support.
  * Improved the [MCP server](/reference/mcp-server) by adding 21 new tools covering browser pools, computer controls, proxies, extensions, and more. Consolidated 36 individual tools into 10 streamlined tools and enhanced the computer\_action tool to support executing multiple actions in a single call.
  * Added API support for clipboard operations, enabling programmatic copy/paste between your automation code and the remote browser.
  * Introduced human-like Bezier curve mouse movements for more natural-looking browser interactions that better evade bot detection.
  * Added an option to disable live view logging, reducing noise when debugging browser sessions.
  * Added `kernel deploy delete` and `kernel app delete` commands to the [CLI](https://github.com/kernel/cli) for removing deployments and apps.
  * Added server-side session ID search to the dashboard, allowing users to find past browser sessions by ID without loading them all locally.
  * Added profile pagination and search to the dashboard and [CLI](https://github.com/kernel/cli), fixing crashes for users with large numbers of profiles.
  * Pre-installed ssh and websocat in browser [images](https://github.com/kernel/kernel-images) for easier debugging and WebSocket testing.
  * Added more fonts to browser images for better rendering of international content.
  * Improved profile upload performance by buffering zstd archives in memory instead of writing to temp files.

  ## Documentation updates

  * Added a new [Yutori computer use](/integrations/computer-use/yutori) integration guide with setup instructions and code examples.
  * Clarified [viewport](/browsers/viewport) configuration recommendations with guidance on choosing the right resolution for your use case.
</Update>

<Update label="February 20" tags={["Product", "Docs"]}>
  ## Product updates

  * Added mouse position tracking to the [CLI](https://github.com/kernel/cli), enabling retrieval of current mouse coordinates.
  * Updated Yutori computer use [templates](https://github.com/kernel/cli/tree/main/pkg/templates) to support the n1-latest model for improved agent performance.
  * Updated [Managed Auth](/profiles/managed-auth/overview) by adding subdomain-based sign-in support, better error handling for `401 Unauthorized` and `410 Gone` responses, and enhanced error messaging with structured error codes and actionable guidance.
  * Improved browser display by auto-toggling Chromium app mode on small viewports for a cleaner, more immersive experience.
  * Fixed screen resize accuracy by removing unnecessary rounding in `ChangeScreenSize` to ensure pixel-perfect display dimensions.

<Update label="February 13" tags={["Product", "Docs"]}>
  ## Product updates

  <YouTubeVideo videoId="lK3YR8qzeH4" title="Introducing Managed Auth" />

  * Launched [Web Bot Auth](/browsers/bot-detection/web-bot-auth) in partnership with Vercel, enabling agents to cryptographically sign requests and prove they're legitimate instead of getting blocked by bot detection.
  * Released [Managed Auth](/profiles/managed-auth/overview), simplifying authentication by securely logging into any site without custom auth flows or exposing credentials to the LLM, and maintaining up-to-date credentials.
  * Added a `POST /computer/batch` [endpoint](/api-reference/browsers/execute-a-batch-of-computer-actions-sequentially) for executing multiple computer actions in a single API call, reducing round-trip latency for complex automations.
  * Improved the [CLI](https://github.com/onkernel/cli) by adding new commands for managing auth connections, supporting `-o json` output for `kernel ssh --setup-only`, allowing pool names as positional arguments in `kernel browser-pools create`, and enabling file exclusions when publishing extensions.
  * Improved input reliability with context-aware timing in key press and mouse drag operations.
  * Fixed an issue where stealth mode browsers couldn't access plain HTTP websites due to forced HTTPS redirects.

  ## Documentation updates

  * Clarified [pricing](/info/pricing) for headful browser sessions.
  * Added comprehensive [Managed Auth](/profiles/managed-auth/overview) documentation, including billing guidance.
</Update>

<Update label="February 6" tags={["Product", "Docs"]}>
  ## Product updates

  * Added a `/json` endpoint to the CDP proxy, enabling native Playwright `connectOverCDP()` connections.
  * Launched an [API](/api-reference/browsers/get-the-current-mouse-cursor-position-on-the-browser-instance) to get the current cursor position, which is useful for debugging and building adaptive automation logic.
  * Released an [API](/api-reference/invocations/list-browsers-for-an-invocation) to retrieve browser session IDs associated with a specific invocation.
  * Added [SSH access](/browsers/ssh) to Kernel browsers for debugging, running commands, and tunneling your local development server to the browser.
  * Enabled support for the [1280x800 viewport](/browsers/viewport#supported-viewport-configurations) size, which improves click coordinate accuracy.
  * The Live View clipboard now syncs correctly between browser and local machine.
  * Chrome address autofill prompts are now automatically disabled.

  ## Documentation updates

  * Added a [pricing calculator](/info/pricing#pricing-calculator) to help you estimate costs based on your plan, session length, and browser type.
  * Clarified [file](/browsers/file-io) access limitations and browser session deletion behavior.
</Update>

<Update label="January 30" tags={["Product", "Docs"]}>
  ## Product updates

  * We changed the default search engine for Kernel browsers to DuckDuckGo, which reduces CAPTCHA friction during web searches.
  * We updated the Gemini Computer Use [Python](https://github.com/kernel/cli/tree/main/pkg/templates/python/gemini-computer-use) and [TypeScript](https://github.com/kernel/cli/tree/main/pkg/templates/typescript/gemini-computer-use) templates to use Kernel's Computer Controls API.
  * We released [skills](https://skills.sh/?q=kernel/skills) for Kernel, so you can easily build browser agents directly from Claude Code.

  ## Documentation updates

  * We published a [Scaling in Production guide](/browsers/scaling/overview) with recommendations and best practices for handling high-concurrency workloads. Read it to learn how and when to use browser pools versus on-demand browsers, and see code samples for production implementations.
  * Added a new [integration guide](https://www.kernel.sh/docs/integrations/agent-browser) for [Agent Browser](https://github.com/vercel-labs/agent-browser), Vercel's headless browser automation CLI, which has built-in support for Kernel browsers.
</Update>

<Update label="January 23" tags={["Product"]}>
  ## Product updates

  <YouTubeVideo videoId="JICMuiC7H4M" title="Introducing Browser Pools" />

  * [Browser pools](/browsers/pools) are now generally available for our Startup and Enterprise plans! Make your startup times even faster with a fleet of instant browsers that come pre-loaded with the logins, cookies, and extensions your agents depend on.
  * We improved the Browsers page user experience. Enjoy instant clickability of browser cards, shift+click range selection, preserved view state when switching between grid and list views, a live toggle for auto-refresh, keyboard shortcut support (Cmd+B / Ctrl+B to toggle sidebar), and more.
  * We added support for viewing [replays](/browsers/replays) of deleted browser sessions. Deleted browsers now navigate to their detail page, which shows the replay player with multiple replays displayed as tabs. The API now supports fetching deleted browser details using new query parameters.
  * Overhauled our [Anthropic Computer Use template](https://github.com/onkernel/cli/tree/main/pkg/templates/typescript/anthropic-computer-use) to use Kernel's [Computer Controls](/browsers/computer-controls) API instead of Playwright, improving reliability and performance.
  * We improved the [live view](/browsers/live-view) experience to show a clear "disconnected" screen when a browser is destroyed, instead of leaving users on a blank page.
</Update>

<Update label="January 16" tags={["Product", "Docs"]}>
  ## Product updates

  * Added a Past Sessions view to the [dashboard](https://dashboard.onkernel.com/) showing your 100 most recent browser sessions; provided context about the session history limit.
