why depend on version 3 of libgnome and libgda + current versions

[A.M. Abdelaziz]

when I installed glade3 it pulled:
libgnomedb3 and libgnomedb (which is version 4)
libgda-3_0-3 and libgda-4_0-4
I tried uninstalling:

libgnomedb3
glade3-libgnomedb3
libgda-3_0-3

and everything is fine, glade doesn't spit any errors or warnings that
didn't exist before.

so why have old versions + current version?

my system is openSUSE 11.2 x86 GNOME, installed glade3 from yast

I thought maybe this is an openSUSE issue, but maybe u have something to say
?
