Semantic Kernel
Semantic Kernel is the enterprise-facing half of the lineage that Microsoft consolidated into Microsoft Agent Framework, and it is the framework that carried plugin-based agent orchestration into .NET and Java shops; recording it as superseded preserves that reach while pointing adopters at the maintained path.

- The README (fetched 2026-08-29) opens with an important notice: "Semantic Kernel is now Microsoft Agent Framework!" It describes Microsoft Agent Framework as "the enterprise-ready successor to Semantic Kernel," now at a production-ready 1.0 with stable APIs and long-term support, and points readers to a Semantic Kernel migration guide. Unlike AutoGen, the README carries no maintenance-mode notice and the repository still received commits on 2026-08-27.
