Stambia DI Designer 2020 (S20.2.1) and Stambia DI Runtime 2020 (S20.2.1) are available at download.
Those maintenance versions include a small fix on HTTP REST Component which was including too much dependencies libraries in previous version.
This was leading to having a larger archive file for the Designer and for the HTTP REST Component.
