Probably. However, if someone wants IDEA support for whatever reason there
is still the IDEA plugin. It still works with GnuPG 1.4.10 for both Linux
and Windows, although I have not tested it with the 2.0 versions.

Why is that? Forced upgrading?

Anyway, pgp 2.6.3ia builds just fine on modern Linux and win32 platforms.
For win32, all you have to do is make a project file including all source
files in Visual Studio and compile it. Long filename support etc. comes
automatically so windows users don't have to be stuck with some DOS
executable which would be a pita.
