OpenCoarrays 2.0.0 Released

OpenCoarrays 2.0.0 has been released. According to the release notes, this release adds support for:

• Fortran 2018 teams (note that this requires the use of GFortran 8.x, currently under development)
• Fortran 2018 QUIET specifier in STOP and ERROR STOP statements
• Fortran 2008 allocatable & pointer components of derived-type coarrays

Since Fortran 2008 (with the inclusion of coarrays in the standard), Fortran has been a PGAS programming language. Fortran 2018 adds additional enhancements for coarrays (including the teams feature, and support for detection of failed images). OpenCoarrays is an open source (permissive BSD license) library that enables coarray support in the GFortran compiler.
