A glimpse towards Version 3...

Version 3.0 has feature freeze and the intense testing phase begins now from start of august 2026. As a major release, a lot has changed under the hood: Version 3 is based on Qt6 and SDL3. For the execution of C-programs, a new virtual machine had been implemented, that runs about 10 times faster compared to the previous one. The support for SDL2 is discontinued in favor of SDL3. With the header <sdlite3.h> a lot of SDL3 functions including the main callbacks can be directly used in the IDE without the need of installing a development version of the SDL3. The classical SDL1.2 is still supported for compatibility of  older program examples. Junior game programers can directly start with the IDE :-)
