One of my customers complained that his EPICS 3.13.2 client cannot connect any longer since the IOC has been upgraded

I checked and 'caget' from the current 3.14 works with 'softIoc' from current 7.0.

(Don't tell me that  he should upgrade, please.)

I won't tell you that he _must_ upgrade, but I will certainly say that he _should_.

An alternative solution which one of our beamlines uses for a similar kind of problem would be for him to run a CA Gateway (built with Base 3.15.x) on the machine that his client runs on, with its server side listening on localhost. Then you configure his client to run with EPICS_CA_ADDR_LIST pointed to localhost and set AUTO_ADDR_LIST to NO, so all of its IOC traffic goes through the gateway.
