SourceTree for Windows 2.0: New UI, faster performance, and Microsoft Git Virtual File System support

SourceTree for Windows 2.0 introduces a refreshed UI with a modern look and feel, improved repository browsing experience, and enhanced workflow for common operations. Performance has been significantly improved by implementing a hybrid LibGit2 handler for most Git operations, resulting in up to 2x speed improvements in some cases. Additionally, support for Microsoft's Git Virtual File System (GVFS) has been added, making it easier to work with unusually large repositories by only downloading files as they are opened.
