is there a quick and reliable method to find out what functionality is deprecated and what is not? for me, using opentk goes hand in hand with learning opengl. and whenever i go google for some tutorials or code snippets, i find a lot of forum messages that say "dont use this, use that instead, its been introduced in opengl x and deprecated in opengl y". some disagree with each other, some seem to confirm each other, and some seem to be plain wrong.
anyone knows a quick way to verify those?
