This is an overview of Fortran 95 language features. Included are the additional features of TR-15581:Enhanced Data Type Facilities, which have been universally implemented. Old features that have been superseded by new ones are not described – few of those historic features are used in modern programs although most have been retained in the language to maintain backward compatibility. The additional features of subsequent standards, up to Fortran 2023, are described in the Fortran 2023 standard document, ISO/IEC 1539-1:2023. Many of its new features are still being implemented in compilers.[1]
