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
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.
