Here KDE 4.13.2 comes. Big release changelogs could be read here:
http://www.kde.org/announcements/4.12/http://www.kde.org/announcements/4.13/
Critical things you should be aware of:
1. Nepomuk is gone, it's superseeded by Baloo. Nepomuk libraries
are still here, though, but they do rely on Baloo internally.
2. kdnssd was renamed to zeroconf-ioslave;
3. kwallet was renamed to kwalletmanager;
4. Akonadi cache will be rebuilt; this could result in change
of PIM folder indexes, which in turn could mess up your
mail filters - beware.
5. ... a lot of other little problems that always happen during
update.
Things could be broken for a day or two in subtle ways - don't
hesistate on reporting them!
* @conflict markers relative to KDE3 packages added, to be used soon.
* Migration to Ruby 1.9 for corresponding ports. Also added @pkgpath to
x11/ruby-qt4 in x11/kde4/ruby-qt, because they are really the same
(except that x11/ruby-qt4 contains also smokegen and smokeqt stuff).
* kde-base-artwork and kde-wallpapers leaved at 4.10.4 because they:
1) did not change; 2) are heavy enough.
