Removed support for GroupShare 2015
Trados Studio 2021 SR2 introduces major improvements that are only supported by the TM Service component that powers Trados GroupShare 2017 or later. As a result, users are no longer able to use or log in to Trados GroupShare 2015 server. If you are still using Trados GroupShare 2015, upgrade to a later version before installing Trados Studio 2021 SR2.
