  • iOS: Text-mode reports printing support added




  • Import / Export users in GXflow's client


  • The consistency of GetPath, GetName and GetAbsolute methods of File data type have been improved (Results differ respect to previous versions when working with files returned by Storage Provider API methods).
  • For iOS offline apps, the empty value for Dates changes from 1970-01-01 to 01-01-01.
