Hi guys, We are starting to use Fuel to exchange data daily, but without exactly the same version of Fuel loaded, exported data is just too frequently not importable anymore. And exception report is meaningless, you can only guess that Fuel version is to blame. So, it is more that a time to: - stabilize and freeze the file format - put a version info into a file and check it while importing - meaningful error reporting in such cases This is IMHO more than necessary for Fuel to become a production ready serializer and I'd say Fuel is now "old enough" to become such :) Best regards Janko -- Janko Mivšek Svetovalec za informatiko Eranova d.o.o.
