gfortran 9 (current development version)
Asynchronous I/O is now fully supported; a program needs to be linked against the pthreads library in order to use it.
The BACK argument for MINLOC and MAXLOC has been implemented.
FINDLOC has been implemented.
IS_CONTIGUOUS has been implemented.
Direct access to the real and imaginary parts of a complex variable via c%re and c%im has been implemented.
Type parameter inquiry via str%len and a%kind has been implemented.
C descriptors, the ISO_Fortran_binding.h file and associated procedures have been implemented.
The MAX and MIN intrinsics are no longer guaranteed to return any particular value in case one of the arguments is a NaN. Note that this conforms to the Fortran standard and to what other Fortran compilers do. If there is a need to handle that case in some specific way, one needs to explicitly check for NaN's before calling MAX or MIN, e.g. by using the IEEE_IS_NAN function from the intrinsic module IEEE_ARITHMETIC.
