RAD (Rapid Application Development) concept using the Pascal programming language. C++ Builder can create native applications for the following platforms: Windows, Android, iOS, MacOS, and Linux (Enterprise Edition only). With Delphi, you can quickly and easily create mobile applications for Android and iOS using a single code base that can be compiled for both Android and iOS, enabling a single programmer to develop for multiple platforms simultaneously.

Features in C++Builder:

1. Clang 20 Upgrade
   • Win64 Modern compiler (bcc64x) upgraded from Clang 15 to Clang 20.
   • Better compatibility with modern C++ and third-party libraries.
   • More precise error messages, clearer template diagnostics, and broader warnings.
   • Makes open-source development more predictable and reliable.
2. C++23 Support
   • New Win64 Modern projects default to C++23.
   • C++17 and C++20 remain available.
   • Key features include:
     • Deducing this – simplifies member functions and CRTP patterns.
     • [[assume()]] – provides portable optimization hints.
     • Range-for lifetime extension – reduces temporary-lifetime issues.
     • static operator() / static operator[] – avoids unnecessary this.
     • if consteval – cleaner compile-time vs. runtime branching.
3. LLDB 20
   • Upgraded debugger backend to LLDB 20.
   • Faster shared-library parsing for large projects.
   • More accurate breakpoints in inlined code.
   • Improved debugging performance and reliability.
4. CMake & Third-Party Libraries
   • Improved CMake integration with bcc64x and Ninja.
   • Supports multiple targets through set_embt_target().
   • Better compatibility with libraries such as OpenCV, Google Test, and VTK.
   • Many libraries can now compile without C++Builder-specific patches.
5. FireMonkey (FMX)
   • Better animation stability and graphics performance.
   • Improved touch, scrolling, and bounce controls.
   • GPU-assisted bitmap transfers.
   • New TApplicationEvents and TMaskEdit components.
   • Improved Skia4Delphi integration and overall performance.
6. VCL for Windows
   • Improved scrolling, title-bar customization, and WebView2 integration.
   • UI improvements for TControlList, TFormTabsBar, and TToggleSwitch.
7. Native 64-bit IDE
   • C++Builder IDE is now native 64-bit.
   • Supports more memory and provides better stability for large and complex projects.

RAD Studio 13 CE modernizes the C++Builder ecosystem with Clang 20, C++23, LLDB 20, better CMake/library compatibility, improved VCL/FMX features, and a native 64-bit IDE.
