I was thinking like something in the help tab on the program, in the text box below after an update, or even underneath the download link on the website.
I know that you guys update frequently, and with out a doubt I'm sure you make massive changes that you could write an entire essay about that a user wouldn't even notice. ....So with that in consideration, You wouldn't have to go crazy, you could summarize massive essays worth of change into something simple like:
-Slightly improved way ability of models to learn, Users likely won't notice.
What are your thoughts on that?
