Update notes

If you are updating from a ProCall Infinity (DataCenter) version <= 2303.x, please note the update instructions for version 2306.0.
When updating from versions <=2210.5 to a version >= 2403.0, you must update to one of the two versions 2306.0 or 2310.0 as an intermediate step so that the contents of the configuration database are migrated correctly with regard to line management.
When updating from versions <=2403.x to a version >= 2406.0, all servers of the multi-server network must be terminated and the configuration database must be updated using an individually provided script before the UCServer updates can be continued.

ProCall Infinity now also uses DNS SRV entries for automatic UCServer detection on laptops managed by Microsoft Intune and not domain-connected.

The size restriction also applies correctly to log files that are written when the service is started.
