See the WHATSNEW file for configuration parameters added, changed, or
removed.

v3 and v4 are quite different.

That depends on a lot of things; and isn't really Samba specific.

But:
  (a) Kerberos is good
  (b) Using a directory services centric approach is good
  (c) Policies are good
  (d) Integrated DNS is good

It is a lot to learn, but Active Directory is in every possible way a
superior solution than NT4 Domains.

If you want to be an Active Directory domain controller you must be
version 4.

If you just want to be a file/print server [even as a *member* of an
Active Directory domain] then stick with version 3.
