When attaching to a remote endpoint, the server decides which browser it runs, which may differ from the configured browserName.

## What's New ### New Tools - **`browser_start_recording` / `browser_stop_recording`** (opt-in via `--caps=devtools`) — Record actions that the user performs manually in the browser and return them as Playwright code. Useful when the user wants to demonstrate a flow instead of describing it ([#42359](microsoft/playwright#42359)) ## Bug Fixes - The default `--codegen` language is inferred from the environment ([#42150](microsoft/playwright#42150)) - Honor `--user-data-dir` in extension mode ([#42190](microsoft/playwright#42190)) - Do not treat orphaned browser preferences entries as an installed extension ([#42224](microsoft/playwright#42224)) - `browser_take_screenshot` returns the original screenshot bytes instead of silently downscaling them to model-specific limits ([#42406](microsoft/playwright#42406)) - Drop the cached browser backend after `browser_close` with a shared browser context, so subsequent tool calls from the same client no longer fail ([#42365](microsoft/playwright#42365)) - When connected to a remote endpoint, `browserInfo` reports the browser actually running remotely instead of the configured one ([#42228](microsoft/playwright#42228)) - Do not clobber the `chromiumSandbox` setting from the config file ([#42288](microsoft/playwright#42288)) - Do not run the heartbeat for HTTP clients that have not opened an event stream ([#42189](microsoft/playwright#42189)) - The internal `/killkillkill` endpoint is no longer registered outside of tests ([#42133](microsoft/playwright#42133))
