The "newer" version of Fortran is Fortran 2018. The working draft for the next standard is https://j3-fortran.org/doc/year/21/21-007.pdf. ISO Standard versions: ISO R 1539-1972 FORTRAN 66 Fortran IV, ANSI X3.9-1966ISO 1539-1980 FORTRAN 77 ANSI X3.9-1978ISO/IEC 1539- 1:1991 Fortran 90ISO/IEC 1539-1:1997 Fortran 95ISO/IEC 1530-1:2004 Fortran 2003ISO/IEC 1539-1:2010 Fortran 2008ISO/IEC 1539-1:2018 Fortran 2018 Fortran 66 was the first language standard published by ANSI. At that time, it was by far the longest standard -- 39 pages -- that ANSI had published. The longest previous standard was a two-page standard for screw threads. The difference between the "year number" such as "90" in the informal name, and the ISO publication date, was because the Fortran committees' preference had been to denote the version of the standard by the year that technical content was frozen. Technical content for Fortran 2018 was frozen in 2015, but a policy change was voted to denote that standard, and future ones, by the year ISO got around to issuing a publication. Although the technical content of the next standard was frozen in February 2021, it will probably be published in 2023.
