We started Joomla extensions development from Version 2.5. During those days, we went through many training materials and able to complete the extension. Later as many releases evolved, and whenever we hit a problem on any method or functionality (due to deprecation/removed) we managed to search in the internet (Joomla official site or stackexchange or any other) and able to find its equivalent.
Our components are now working in 3.9 version and we are pretty sure many of the functions which we are using in our extension are deprecated.
Is there a common place where we can identity which functions are deprecated in X release and what is their equivalent in the newer release?
