Please excuse my ignorance. What is "New.Of"?

See Marco's blog post.

From the documentation: http://docwiki.embarcadero.com/RADStudio/Tokyo/en/64-bit_Windows_Application_Development. The RAD Studio build system automatically embeds an RC_DATA resource in the Win32 package binary named PLATFORMTARGETS, which is a bitmask of the pidXXX constants in System.Classes.pas and reflects the package project's targeted platforms. The IDE reads this resource when the package is loaded and uses the resource data to decide, for example, whether or not to disable the component(s) in the palette when an unsupported platform is active. Targeting multiple platforms with a component package implies a contract between the component developer and the IDE. The IDE assumes that if a component package project targets multiple platforms and the developer distributes the Win32 run-time package to customers (and all the associated compilable and linkable files), the developer will also distribute all the necessary compilable, linkable, and run-time bits for the other targeted platforms as well. Individual components can use the ComponentPlatformsAttribute class attribute to override the data in PLATFORMTARGETS, using a bitmask of the same constants in the Classes unit. For example: type [ComponentPlatformsAttribute(pidWin32 or pidWin64)] // Only supported on Win32 and Win64 TMyComponent = class(TComponent) private ... end; So to get the components to be usable with other plagorms, all you need to do is before you compile the Design package to add the other platform to it. They won't be used but just being there makes the build system to include the appropriate resource flagging the package as usable for the platforms. I have tested this and it works!
