- Revamp whole DB to Display flow - Filter Pipeline, arbitrary filtering and sorting - Binary tree arrays for faster lookup & manipulation - DB: introducing custom functions - DB scheme: split req into heap & cache - cache written by GlassVPN only - heap written by Main App only - Introducing DB separation: DBCore, DBCommon, DBAppOnly - Introducing DB data sources: TestDataSource, GroupedDomainDataSource, RecordingsDB, DomainFilter - Background sync: Move entries from cache to heap and notify all observers - GlassVPN: Binary tree filter lookup - GlassVPN: Reusing prepared statement
