We just pushed the first RC for the upcoming 6.0.0 version to the Distributors Portal. Customers who would like to test are very much appreciated! (Pls. check with the distributor to get access to unstable releases as well, if you do not see them on your account.)
The 6.0.0 version brings a completely dockered and therefore dependency free installation plus new checks and options. Please read the release history for details.
