No there isn’t.
GSE requires a complete rewrite from scratch. I would have been close to a release for the 5th however I have been waylaid by a funeral interstate. I am travelling home tomorrow and will then get back to work.
There will be an early alpha of GSE 4 available to GSE Patrons within a few days of the 5th.
To understand what is happening I would suggest reading: War within and future of add-ons?
