The final update to studioSL 2019 has been released and will bring studioSL to 2019.1218. Early next year, Streamsim will release studioSL 2020 based on the latest NetBeans and Java platforms. A fresh install will be required to access studioSL 2020. Note that old and new studioSL versions can co-exist.
Happy holidays and best wishes for 2020 and a heartfelt 'thank you' for your continued support.
