Note

Medium Risk
Adds proxy routing and WebMCP custom-tool APIs with reshaped WebMCP types that may break typed consumers; pool acquire/release semantics change when profiles are used at acquire time.

Overview
Release 0.112.0 bumps the SDK to match new Kernel API surface (172 endpoints) with browser networking, WebMCP custom tools, pool profiles, telemetry filters, and org entitlements updates.

WebMCP is reorganized under browsers/webmcp/ and adds client.browsers.webmcp.customTools (list, add, remove) for registering page- or CDP-backed tools. Tool listings and invocations now cover custom tools; listTools accepts exclude_custom. Response types shift to nested ToolMetadata (MCP/WebMCP-aligned annotations and optional outputSchema).

Browsers gain network.proxy_routes for per-host proxy selection (documented as proxy v3, not pools). Browser pool acquire accepts optional profile; releases note that acquire-time profiles force instance replacement even when reuse: true.

Telemetry adds archived type filtering on events, iframe / worker target_type values, clarified monitor_disconnected behavior, and destination_route_unavailable on proxy errors.

Organization entitlements expose a search rollout flag. Version, changelog, and release metadata are updated accordingly.
