Another week, another snapshot 🙂
As of this morning the KDE4:Unstable repository for openSUSE contains a newer snapshot (4.4.86). As that openSUSE:Factory now contains Qt4 4.6.3, all targets for KDE4:Unstable are build with the same Qt4 version, which brings a lot of stability and bugfixes.
A few people already indicated that they find the latest version becoming more responsive and that things seems much faster than previous versions.
I would say grab the new version and try it yourself.
