We publish a change log in the folder of the release and we publish all information about each release here, and always have. 
You must be new, so welcome. This forum is hosted and run by LightBurn. You cannot get much closer to the “right” folks. You are talking to us right here, and we are responding, so why the sad face?
As for product and feature suggestions and requests, LightBurn has hosted a Suggestion Site from the beginning, but had to temporarily suspend access due to things outside our control (was down for a month or two). That has been resolved and the site is active and ready for use again. We ask folks to place their requests there, so we can track interest, inform members as to the status changes to the suggestions and manage the process of getting your feedback for additions.
