Note

Medium Risk
WebMCP ListTools signature and Tool JSON shape are breaking for Go callers; proxy routing and pool profile behavior affect session egress and pool reuse semantics.

Overview
v0.112.0 bumps the SDK to match new Kernel API surface (172 endpoints) and documents the release in CHANGELOG.md / install pins.

Browser networking adds proxy_routes on BrowserNetworkConfig so sessions can send specific host patterns through chosen proxies instead of the session default.

Browser pools accept an optional profile on acquire; release docs note that acquire-time profiles force destroy/replace even when reuse is true.

WebMCP expands materially: client.Browsers.Webmcp.CustomTools supports list/add/remove of custom tools; ListTools now takes BrowserWebmcpListToolsParams (e.g. exclude_custom). Tool payloads nest MCP/WebMCP metadata under tool (with updated annotation field names) and expose custom-tool source fields.

Telemetry adds a type query filter on archived events (AND with category), documents paging with filters, extends CDP target_type with iframe and worker, clarifies monitor_disconnected vs computed state, and adds destination_route_unavailable on proxy errors.

Org entitlements include a new search.enabled rollout flag.
