What Changed
The DevExpress VCL installer no longer supports the following IDEs:
- Embarcadero Delphi XE7 (32 and 64-bit)
- Embarcadero Delphi XE8 (32 and 64-bit)
- Embarcadero C++Builder XE7 (32 and 64-bit)
- Embarcadero C++Builder XE8 (32 and 64-bit)
Reasons for Change
IDEs listed above offer limited language support (lack generics support, anonymous procedures, etc). Projects that rely on major DevExpress UI components (such as the DevExpress RichEdit Control) could encounter compiler, linker, and debugger errors. In addition to limited language support, Embarcadero's VCL library has undergone significant overhaul since 2015. By dropping XE7 and XE8 support, we can optimize our code, maintain a single code base, and embrace modern development methodologies
Impact on Existing Apps
This change affects DevExpress-powered projects targeting RAD Studio XE7 or XE8.
How to Update Existing Apps
To install DevExpress VCL v24.2.1 (and later versions), you must upgrade to RAD Studio 10 Seattle or newer.
