Hi,
To remain compatible with the upcoming Delphi 64-bit release, I've
changed
the 'Tag' property type from Integer -> PtrInt.
Do you already has the info that Delphi will do this change?

The practical upshot from this is that you can store a pointer in it
on all platforms.
(a widespread abuse of the Tag property).
This potentially breaks some existing code if you rely on Tag having a
size of 4 bytes.
If you do not rely on this, it should not break any code. If it does,
I'd be interested
in hearing about it so we can provide workarounds on the website.
