browser-use 0.13.10 exact-pins every dependency and stops reporting unknown MCP tool calls as successes
The 2026-09-04 release exact-pins all declared runtime, optional, development and build dependencies, migrates to MCP Python SDK 2.1.1, pins Pydantic 2.13.5 and Hatchling 1.32.0, adds pydantic-settings 2.15.0 as an explicit runtime dependency, and upgrades pypdf to 6.16.2 to clear three open Dependabot advisories. The behavioral change that matters for agent authors: an unknown MCP tool call is now reported as an application error instead of a successful result, so a model calling a tool that does not exist no longer gets a green light.
