You are right that the Fortran community took a long time adopt standards later than F77. Gfortran handles Fortran 90 and 95 well now, and I think F2003 and F20

You are right that the Fortran community took a long time adopt standards later than F77. Gfortran handles Fortran 90 and 95 well now, and I think F2003 and F2008 (although I don't use too many features from those standards and cannot say for sure from personal experience). I don't remember how mature gfortran was in 2010. Maybe then g95 was more mature.
