The OO paradigm has been supported since Fortran 90, albeit somewhat primitively. Dying? I finished writing my latest Fortran program last week!
Concerning backwards compatibility though, there are some features of Fortran 77 that have been deleted in the latest versions. Not anything that anyone will (or should, for that matter) miss, since I am talking about very archaic features here. I am sure that compilers will still support them though.
Also, kudos to the gfortran people for the good work on the compiler, if anyone is reading this. I have been keeping an eye on the progress and it was dramatic in the last years. Also, the g95 compiler looked dead and I thought that Andy gave up, but now I see an update made on the source in Jan 2013 after 2.5 years. Can someone share an insight?
