OpenProject 4.0.1 was released today. We advise anyone to update their OpenProject installation.
The release fixes installation errors caused by an old version of Sprockets and provides several important security fixes (including a Rails update).
Packager support for easier installation has been extended to also include RHEL, CentOS and Ubuntu (#17165).
