Open-sourcing Sections: Declarative data handling for Litho lists
Oct 26, 2017

Summary
Introduced 'Sections', a declarative and composable API built on top of Litho for writing highly-optimized list surfaces. Sections structures data and translates it into Litho Components, handling data diffing and minimal UI refreshes automatically. It provides building blocks like `GroupSectionSpec`, `SingleComponentSection`, and `DataDiffSection` to manage lists of data and translate them into UI components, significantly improving performance and maintainability for scrollable lists compared to traditional RecyclerView implementations.
