force-v3-sigs not necessary any longer?

[Hasnain Mujtaba]

I did some testing and learned that PGP8.x generates v3 signatures, but it can verify v4 signatures. This is probably for interoperabilty with PGP6.5.8, which cannot verify v4 sigs. 

RFC 2440 describes the difference between v3 and v4 signatures as follows:

   Two versions of signature packets are defined.  Version 3 provides
   basic signature information, while version 4 provides an expandable
   format with subpackets that can specify more information about the
   signature. PGP 2.6.x only accepts version 3 signatures.

Hi,
I have used --force-v3-sigs in my preferences for a long time. Is this not
necessary any longer? What PGP versions can handle V4 signatures?

Besides what is the difference between V3 and V4 signatures? Are V4
signatures safer? How?
