The "old" stable glib release is now at version 2.6.10. From the announcement: --- This is a bug fix release and is source and binary compatible with 2.6.0. --- Lots of bugfixes between Portage version 2.6.5 (current) and this release, but, suffice it to say that there have apparently been a goodly number of stability improvements since 2.6.5's release in June. Thanks!
We are in the process of stabilizing the 2.8 series, so I think that version bumping the 2.6 series isnt worth it.
