Delphi also has enhanced Code Insight support, highlighting warnings and hints in the code editor, new improvements to rendering to enhance visibility, and better support for packages, ctrl-click navigation, and much more.
C++Builder’s Code Insight is updated for robust code completion. C++Builder includes a new approach to debug information which greatly reduces memory strain on the Win64 linker and app output size, known as split DWARF, while an overhaul of the exception handling system provides improved application reliability. The RTL also includes the latest version of the Dinkumware STL.
