1. You can now choose the _platform_ (Windows, Linux, Android, iOS…) to build and run from the editor. This platform is then used by _compile, run, package, install_ build tool commands. This means that, if you have cross-compilers set up (hint: use [fpcupdeluxe](https://github.com/castle-engine/castle-engine/wiki/fpcupdeluxe)) then you can now easily build for various platforms, right from the GUI editor, without resorting to command-line and playing with environment variables.

2. Another new feature, also related to the cross-platform development, is specifically for _Linux/FreeBSD developers that want to target Windows too_: 

3. To make things balanced, we also have one _new feature for Windows developers to make it easier for them to build apps for Unix (Linux, FreeBSD) desktops:_
