[gtkmm] upgrade GTK+ to upgrade gtkmm?

["Akbar Kok" <linux cwazy co uk>]

Hi, just a simple newbie question. Assume I have GTK+ library version
2.4.1 and I installed gtkmm library version 2.4.0. Ok.... time passed
away. Then new version of gtkmm is out. 2.4.4. And newer version of GTK+
is out. 2.4.3.

Do I have to upgrade my GTK+ library just to upgrade gtkmm library? Is
newest version of gtkmm library and related library ( libglademm,
libblablamm, etc ) compatible with earliest version of GTK+ ( 2.4.0 )
?????? I am talking about minor version not about major version.

Thank you.

Regards,

Akbar
