[rules-users] From 4.0.6 to 4.0.4 to 4.0.3

[Matija]

Hi,

just to clarify this, does that mean there are differences between the
free version release and the paid version release? Until now I wasn't
even aware the latter existed. If so, is it possible to learn what
those differences are? Also, are the benefits of support subscription
listed anywhere (specifically for JBoss Rules)? I tried to find it on
the web site but all I could find was the generic JBoss subscription
page, which isn't very informative.

Thanks,

M.
