Best online resource to learn more recent versions of Modern OpenGL?

There is not much. I used this as reference:

more advanced features/techniques like AZDO

AZDO is just a naming convention nVidia adopted years ago to tell that OpenGL can approach Vulkan under some conditions. Main principles are avoid to switch buffers, reduce number of draw calls and use DSA (‘named’ prefixed functions). You can add vertex attrib binding to this list depending on things.

Except for tessellation and compute shaders, GL 3.3 already gives you most of what GL is capable. GL 4.x are mainly adding conveniency / speed stuffs: DSA, SSBOs, and the ‘ugly’ non-mandatory bindless textures or SPIRV for example.

You can also try to OpenGL wiki, it's quite well-formed if you already know OpenGL enough.

@undefined thank you! I'll take a look at it ?

@_Silence_ yes you are right, sorry for the confusion about AZDO.
Thank you, so it seems I am not missing so much for now. Maybe if I want to learn something more I should probably try to switch to Vulkan, despite I find it a bit intimidating for now.

Thank you about the suggestion on the OpenGL wiki, I'll take a look at it ?

@Snaked

Thank you for your links. Hehe I remember the Nehe one! It was where I started learning OpenGL long long time ago :D

Those were obsolete 10 years ago.

fleabay: i hope you dont have thinked much for reach that conclussion

i said cos was a referencing on OGL stuff, buy anyways, much of things people think are obsolete can be “updated or re-coded with minimal changes” ….. i know some people say C/C++ is obsolete too :D ….. o yes Python is better how i dont fall in that before hahahaha :D
