Thank you Brian,

I have upgraded to 4.4.1, after doing minor adjustments to the config.

However, I am now trying to start the upgraded server and I get the 
message (in journal):

    Caught an exception instantiating a backend: launch= suffixes are
    not supported on the bindbackend

I assume something has changed with launch directive and backend config 
format that renders our backend configuration faulty? (Please see our 
config below.)

Any hints to correct things as needed will be welcome!

Our config:
