CWASA Release Notes
CWA Signing Avatars Release Notes
From 2021 the standard Open CWASA release, found at http://vhg.cmp.uea.ac.uk/tech/jas/std/, allows personal, public, and commercial use of the software when accessed, unmodified, from the UEA server. See Conditions of Use.
These notes, and the notes for JASigning, include Legacy releases with additional avatars and earlier deprecated JASigning resources. There is also a Development release containing components that cannot be guaranteed to be stable and should only be used for evaluation.
See CWASA for other resources and documentation, including the CWASA Local Installation, a version that can be installed on a localhost web server for evaluation.
Users are welcome to provide feedback via the Issue Reporting page. Documentation of the system is a work in progress so please send questions and comments to cmp_virtualsigning@uea.ac.uk so that we can update these pages.
