Tarantool 1.7.1 adds a new implementation of CALL command which supports EVAL-style marshalling, i.e. returned data is not converted to tuples anymore. Old CALL command (code = 6) is deprecated.
Please detect Tarantool version on connect and use code=10 for CALL if remote version >= 1.7.1.

After internal discussions we decided that selecting old or new CALL automatically based on the server version is a bad idea after all. Client code will notice the difference in semantics.
Instead we suggest the following: make call behave in 1.7 semantics by default. Add connection option to configure calls semantics. If user wants 1.6 CALL-s, she should say so explicitly.
