The current version of SignStream is 2.2. This version incorporates several bug fixes and ensures that all saved files are in the most current format. SignStream version 3, currently under development, will only open files in this format.
SignStream is distributed on a non-profit basis to students, educators, and researchers, for non-commercial use only. SignStream may not be redistributed without permission.
