Hello,
a new preview build is now available!
An embedded Firebird SQL Database Server is now being used for the reference databases. This adds only 2 MB to the download and it does not need any configuration. It is used for SmartTracking, for the Destination Cache and for storing the checksums for Partial File Updating. The SQL server communicates directly via its DLL file, so there is no TCP/IP or other interprocess communication that would be seen by Firewalls. Embedded Firebird runs as part of the Superflexible or ExtremeSync processes.
More information about version 5 is available here:

Cheers,
Tobias
