为什么值得关注
Playwright MCP version 0.0.79 introduces several tool enhancements and stability fixes. For tooling, browser take screenshot now supports a WebP format option (with automatic extension inference), --codegen supports Python, Java, and C alongside TypeScript, and a new --timeout-settle flag (timeouts.settle config) allows controlling action settle time (defaults to 500ms). Global bounding boxes in snapshots are now supported via --snapshot-boxes. Fixes include browser reconnection after disconnection, explicit error reporting for malformed JSON configs rather than falling back to INI parsing, event-based download detection replacing error guessing, out-of-band dialog state cleanup, and input escaping in codegen. The stale --output-mode CLI option was removed. For the browser extension, extension protocol v1 has been removed, CDP relay WebSocket upgrades now validate Host and Origin headers, and missing browser executable paths now point to PLAYWRIGHT MCP EXECUTABLE PATH.

开发者应核对什么
- Migrate away from extension protocol v1 if using the browser extension, as support has been removed.
- Remove usage of the deprecated --output-mode CLI option.
- Verify JSON configuration files are well-formed, as invalid JSON will no longer silently fall back to INI parsing.
- Optionally configure --timeout-settle if the default 500ms settle delay interferes with fast-paced workflows.
