From the blurb:

A series of significant revisions to the standard versions of the language have progressively enhanced its capabilities, and the latest standard – Fortran 2018 – includes many additions and improvements.

The second edition of "Modern Fortran Explained" expands on the first. Given the release of updated versions of Fortran compilers, the previous separate descriptions of Fortran 2003 and Fortran 2008 have been incorporated into the main text, which thereby becomes a full and unified description of the current Fortran 2008 version of the language. This is much cleaner, many deficiencies and irregularities in the earlier language versions having been resolved. It includes object orientation and parallel processing with coarrays. Allocatable arrays and edit descriptors are now treated in separate chapters.

Four completely new chapters describe the additional features coming with Fortran 2018, with its enhancements to coarrays for parallel programming, interoperability with C, IEEE arithmetic, and various other improvements.
