Description Benjamin Kosnik 2010-10-12 19:18:01 UTC

Description of problem:

RHEL 6 is going to ship with some new documentation aimed at developers. As part of this, some information is requested WRT the gnome runtime support libraries.

See:
file.rdu.redhat.com:~aldyh/devel-guide-draft3.pdf

What is needed is a page, similar to 3.3.4/3.3.5 for Qt/KDE, but for GNOME. In addition, an subject expert or maintainer needs to provide information on ABI/API changes from RHEL 4 to 5 to 6.

Version-Release number of selected component (if applicable):

2010-05-26 Owen Taylor pinged about this, no reply

I feel like I sent mail to the glib/gtk2 maintainers as well but cannot find the record and regardless, no reply. 

Somebody who is in the same physical office should go and pinch them.
