 ## Platform & Library Support
 
-In light of security considerations and limited time available for contribution,
-GpgFrontend will gradually cease to support certain older platforms.
-Furthermore, GpgFrontend will aim to utilize newer and more secure libraries
-whenever possible.

-As of version v1.0.0, we no longer support x32 operating systems. This decision
-stems from time constraints and the dwindling usage of x32 machines in the PC
-market. Consequently, I plan to cease dealing with complex issues associated
-with this system. x64 should suffice for most users, or alternatively, gpg4usb
-can be used.

 From version v2.1.0 onwards, we no longer support macOS 10.15, due to its
-impending discontinuation by GitHub Action. Considering its age, and the

 likelihood of Apple discontinuing support soon, it seems prudent to drop it.
 
-As of version v2.1.1, we no longer support Ubuntu 18.04, as it isn't supported
-by GitHub Action since April 3rd. Thus, all builds will transition to Qt6, since
-Ubuntu 20.04 is compatible with Qt6.

-Starting from v2.1.2, the Qt5 API will be removed from the source code. This
-implies that the entire project will now utilize the Qt6 API and will no longer
-compile under Qt5. Consideration is being given to removing the deb package
-build as well.

+However, the Linux and macOS platforms will primarily move forward with Qt6,
