Sep 1, 2025

September 2025 was focused on accelerating developer productivity, expanding API capabilities, and hardening security and onboarding. Key features delivered include Fern-based API Client SDK generation integration, enabling automated SDK generation with CI/CD workflow changes and example usage updates; real-time capabilities added to the BrowserUse SDK with stream and watch methods and enhanced webhook verification schemas; public API surface expanded to export PollConfig and TaskViewWithSchema; and updated documentation and onboarding (Polish README and QuickStart) to reduce setup friction. Major bugs fixed: In browser-use/browser-use, unified prohibited domains management with SecurityWatchdog, including logic to enforce allowed > prohibited, handling cases with no rules to allow all. Comprehensive tests added for edge cases. This update improves security and reliability in URL blocking. Overall impact: These efforts reduce time-to-value for developers, increase reliability of real-time task updates and webhook handling, provide clearer external API hooks, and strengthen browser security controls. Demonstrated technologies: Fern integration and CI/CD changes, streaming/watching APIs, TypeScript API surface exports, SecurityWatchdog domain filtering logic, and expanded test coverage with documentation improvements.
