Optimize Builds with a Modernized C++ Compiler

C++Builder by Embarcadero is a rapid application development environment that simplifies C++ development for Windows, iOS, macOS, and Android. It streamlines the process by offering visual UI design tools, pre-built components, and a powerful debugger, enabling faster creation of high-performance native applications.

The C++Builder 12.3 release includes an upgrade to the latest Clang-based C++ compiler for Win64 to take advantage of faster compilation, enhanced code safety, and full compatibility with RAD Studio component packages. This update introduces support for both consuming and producing runtime packages. Developers will also benefit from parallelized, CPU-saturating batch compilation, significantly improving build times. With additional performance optimizations and quality enhancements, this release provides a robust foundation for high-performance Windows application development.
