Have a changelog that shows recent updates on the application directly available on the platform in settings so that builders on the platform don't have to hunt in the group to see what posts contain updates.
Most updates on ManyChat get announced in the FB groups and get buried by newer posts within a couple days.
By having an active updated current changelog will help builders and agencies know what updates have been made on the platform whether they be feature requests or bug fixes and keep all users on the same page.
Also provide a way to search for updates in the changelogs, by date and title.
