Note

Medium Risk
Renaming id to id_or_name across many browser methods is a breaking change for positional callers; behavior otherwise follows existing API patterns with additive WebMCP endpoints.

Overview
Release 0.98.0 aligns the Python SDK with browser routes that accept either a session id or name on every /browsers/{id_or_name}/… sub-resource.

Browser sub-resource methods that previously took a positional id now take id_or_name (sync and async), including curl, load_extensions, telemetry, replays, filesystem (and fs watch), process, logs, computer, and Playwright. Request paths use /browsers/{id_or_name}/… accordingly.

This release also adds client.browsers.webmcp with list_tools and invoke_tool for discovering and invoking page-native WebMCP tools. Playwright execute documentation now notes a webmcp helper in the execution context alongside page, context, and browser.
