Currently, all autoclosing branches trigger Herald rules for Continuous Integration and Delivery, meaning that a commit to a Roundcube Kolab Plugins repository rRPK branch roundcubemail-plugins-kolab-3.2 branch (Kolab 3.4, Kolab Enterprise 14) results in an attempt to build the software using Kolab:Development specs.
The version currently in Kolab:Development (as well as other live Kolab branches) should allow for the continuous integration suite Stick to determine what build specifications to use.
