Pi 1.0

Earendil has released Pi 1.0, a minimal and extensible agent harness that has been hardened through months of user feedback and is now ready for production use by individuals and businesses. The release includes new features such as native MCP support, extension capabilities, improved caching, and a redesigned interface, while maintaining Pi's core principle of minimalism by only adopting proven technologies. Alongside Pi 1.0, Earendil is also introducing Pi Durable, an experimental package designed to enable longer-running agentic applications across different platforms while preserving Pi's minimalist philosophy.
