Removed virtual specifier from SetConnectTimeout() and SetReadTimeout(), not
being used by any descendants.

Answer : DELPHI 2010 -- INDY 9 or INDY 10

AFAIK is still well supported (last Dev release is dated July 25, few days ago http://indy.fulgan.com/zip/)

The 10 version was needed for compatibility and implamentations with .net. That's why there're so many differences between 9 and 10, but I'm pretty sure that the support still will exists for long time.
