When is the new release of BIML express planned?

Currently we are working with the latest version version of BIML express (2019 R1). 
This version is a blocker for us to upgrade Visual Studio and SSIS to the latest version. 
When is a newer version of BIML express planned with latest VS support and SSIS 4.2 support?
Perhaps Varigence can give some insights in the BIML express release calendar.

Is this still a supported product by Varigence?

Thanks in advance.
