I have purchased a couple of your products (Joomdonation and Events Booking). My download period for Events Booking has expired and I notice you have created a newer version. Is there any way to tell what has been added/fixed between the version I run and the current version. Sort of a change log from the development process? I run these on a church website and we don't have much money to support this so I would like to see if the updates are something we would need before I invest our meager resources in them.
