Linux64
Linux64 is a new target platform which was introduced in Delphi 10.2 Tokyo. Recently in early Spring 2020 uniGUI also introduced its first implementation of the Linux64 platform. uniGUI implementation for Linux64 supports Delphi 10.3 and later.
In the earlier implementation of Linux in Delphi 10.2, the ARC memory manager model was introduced and it was the only option. Starting from Delphi 10.3 Rio the non-ARC memory manager was also introduced and became the default memory manager for the Linux platform. This means that Delphi Linux applications can adopt the same memory model that conventional Delphi Windows applications use.
We also decided to start supporting Linux from Delphi 10.3, so you will be able to compile uniGUI apps for Linux64 without a need to adopt the ARC memory model.
