## What's New ### Tool Improvements - **`browser_take_screenshot` — WebP format** — New `type` option to pick the image format (`png`, `jpeg` or `webp`); when unset, the format is inferred from the filename extension ([#41152](microsoft/playwright#41152)) - **`--codegen` — more languages** — Code generation now supports `python`, `java` and `csharp` in addition to `typescript` ([#42106](microsoft/playwright#42106)) - **Configurable settle delay** — New `--timeout-settle` flag (and `timeouts.settle` config option) to control how long to wait after each action for triggered work (navigations, requests) to settle, defaults to 500ms ([#41924](microsoft/playwright#41924)) ## Fixes - Aria snapshot capture is skipped when the response discards it ([#41923](microsoft/playwright#41923)) - New `--snapshot-boxes` flag (and `snapshot.boxes` config option) to enable bounding boxes in snapshots globally — previously this was only available per command ([#42102](microsoft/playwright#42102)) - Reconnect to the browser after a disconnect ([#41966](microsoft/playwright#41966)) - Report malformed JSON config instead of silently falling back to INI parsing ([#41909](microsoft/playwright#41909)) - Clear the dialog modal state when a dialog is closed out of band ([#42032](microsoft/playwright#42032)) - Detect downloads via the download event instead of guessing from `net::ERR_ABORTED` navigation errors ([#41933](microsoft/playwright#41933)) - Surface the missing executable path when a browser isn't installed ([#41941](microsoft/playwright#41941)) - Escape user input in codegen output ([#41962](microsoft/playwright#41962)) - Removed the stale `--output-mode` CLI option ([#41833](microsoft/playwright#41833)) ### Browser Extension - Validate `Host` and `Origin` headers on CDP relay WebSocket upgrades ([#42103](microsoft/playwright#42103)) - Launch the Chrome profile that has the extension installed ([#41939](microsoft/playwright#41939)) - Pass `noDefaults` for extension CDP connections ([#42119](microsoft/playwright#42119)) - Mention `PLAYWRIGHT_MCP_EXECUTABLE_PATH` in the error shown when the browser executable is not found ([#42122](microsoft/playwright#42122)) - Removed support for extension protocol v1 ([#41857](microsoft/playwright#41857))

Summary
waitForCompletionsleeps a hard-coded 500ms after every action (and another 500ms when requests fired). That is the right default for step-at-a-time driving, but batchedbrowser_run_code_unsafescripts that do their own waiting pay it on every call.timeouts.settle(default 500ms, unchanged) with the usual plumbing:--timeout-settle,PLAYWRIGHT_MCP_TIMEOUT_SETTLE, config file key, anddefaultConfigentry.
