Sometime in the next couple of days when all the GSC/etc flaws are ironed out.
Updated exe files are posted here, not on GitHub, only when they are sufficiently tested. Over 100,000 people have downloaded the latest release in the past 2 months; stability is favored over rapidity -- corrupting / misrepresenting data is to be avoided.
As for ancillary feature requests, the code is public and anyone can make improvements. Entree Forest can be edited with other tools, and a mass gift converter doesn't fit well in the main program (nor would it be worth adding in as a main feature -- it's something one person runs once then distributes the files. It's like 10 lines of code to do that so someone can script it up just fine).
