to get new features not yet released you need to update from CVS. Be advised that some of the code can kill you install.
su - projop cd packages export CVSROOT=":pserver:anonymous@berlin.dnsalias.com:/home/cvsroot" cvs login cvs update -PdA
after the CVS login you will be asked for a password. Just press <ENTER> and carry on from there.
if an sql script takes a dump during the upgrade then install it per hand.
su - projop cd /web/projop/packages/intranet-core/sql/postgresql/upgrade psql -f upgrade-3.x.x.x-3.x.x.x.sql
