System V R 3.1,3.2,3.3, 4 ? What's the diff ?

[Simon J. Gerraty]

Ok, I have asked all the System V guru's I know.  (Even tried
AT&T :-) and  have got nowhere.  So perhaps the net can help.

Can anybody provide a list (succinct if possible) of the major
changes introduced with System V 3.1,3.2 etc.  A reference to a
suitable source would also be useful.

Frequently we (a computer vendor) respond to tenders that call
for say System V 3.3.  In one case the tender asked for 3.3 only
weeks after AT&T announced it.

In many cases the customer simply wants the latest and greatest
of whatever... In other cases they do have a need for specific
features that may have been introduced with a particular
release.  (Ok, most clever software writers try and avoid such
release dependance but...).

My company sells a Unix derrived from Sys V 3.1, with
enhancements such as FFS from BSD etc etc.  It may well be the
case that our Unix does indeed provide the feature that the
customer want's - but without a list of the differences between
releases we don't know.

Thank you (in advance :-)
