We have updated our OpenGL headers to support the latest OpenGL 4.4 specs. So if you're using Delphi and/or Free Pascal and want to use all of the latest features OpenGL has to offer, please visit their english wiki-page for the header and grab a copy of it.
Note that the header also includes support for all older OpenGL versions, so it may worthwhile updating even if you're not using the latest cutting-edge features of OpenGL 3.x/4.x. The changelog is available and can be accessed through the wiki as well here.
Get the new DGL OpenGL Headers at wiki.delphigl.com.
The header supports Free Pascal (Windows, Linux, Mac OSX) as well as Delphi (Windows, Mac OSX hasn't been tested yet).
