+## Product updates
+
+- Added a `playwright_execute` tool to [`@onkernel/cua-agent`](https://github.com/kernel/cua) for combining computer use with Playwright automation, plus support for `gemini-3.5-flash` as a CUA model. 
+- Extended the [MCP server](/reference/mcp-server)'s browser pool tool with SDK parity fields (`start_url`, `chrome_policy`, `kiosk_mode`, profile and viewport settings, `fill_rate_per_minute`) and a structured acquire/release workflow. Added parity for actions across `manage_apps` (`delete_deployment`, app/deployment search), `manage_proxies` (`get`, `check` with optional `check_url`), `manage_profiles` (`get`, paginated search), and `manage_projects` (`get_limits`, `update_limits`).
+- Added a `start_url` parameter to browser pool `acquire`, letting each acquired session override the pool's default start URL.
+- Added `--chrome-policy` flags to `browsers create`/`update` and `browser-pools create`/`update` in the [CLI](https://github.com/kernel/cli) for setting Chrome popup, PDF, and homepage behavior from the terminal.
+- Extended `kernel browsers update` in the [CLI](https://github.com/kernel/cli) with `--name` and `--tag` parameters, so a running session's name and tags can be changed after creation alongside the existing `browsers create`/`acquire` flags.
+- Brought custom session names and tags into the dashboard: the launch dialog now accepts an initial set of tags, sessions can be renamed and re-tagged after creation, and tag chips on the sessions list are click-to-filter — so the names and tags set via the API are actionable from the UI, making it easier to find a specific session out of many concurrent ones.
+- Added an API key [rotate endpoint](/api-reference/api-keys/rotate-an-api-key) (`POST /org/api_keys/{id}/rotate`) that issues a replacement key, copies the rotated key's name and project scope, and keeps the old key working for a configurable grace period (default 7 days). 
+- Shipped a `generate-video` [skill](https://github.com/kernel/skills) for producing smooth, deterministic MP4 videos from a web scene — used internally for launch and explainer clips.
+
+## Documentation updates
+
+- Enabled dark mode on the docs.
+- Added a common use cases section to the [policy.json](/browsers/pools/policy-json) page with `browsers.create()` examples for popup blocking, PDF inline rendering, and homepage overrides.
+- Documented [`X-Kernel-Project-Id`](/info/projects) header resolution rules and direct project and extension lookups on the Projects page.
+- Documented the API key [rotate endpoint](/api-reference/api-keys/rotate-an-api-key), including the optional `days_to_expire` and `expire_in_days` parameters.

 - Browser sessions now play audio by default, and the browser replay recording API gained a `record_audio` option to capture that audio in replay videos.
 - Extended browser telemetry to the [CLI](https://github.com/kernel/cli): use `--telemetry=all|off|<list>` on `browsers create` and `browsers update` to configure telemetry per session, and `kernel browsers telemetry stream <id>` to tail live events with category and type filters and SSE resume support.
 - Added API key management commands to the [CLI](https://github.com/kernel/cli) for creating, listing, retrieving, updating, and deleting org API keys directly from the terminal.
-- Expanded the [MCP server](https://www.kernel.sh/docs/reference/mcp-server) from 10 to 16 tools, adding managed auth (`manage_auth_connections`, `manage_credentials`, `manage_credential_providers`), `browser_curl` for HTTP(S) through a live browser, API key management, and project management. MCP-created browser sessions also now accept the same configuration as the API.

 - Browser sessions can now be given a custom name at create time, making them easier to identify in the dashboard and audit logs.
 - Improved `kernel status` to distinguish between the API being down versus unreachable.
