    • Interoperable with GNU versions up to and including GCC 8.1
  • Fortran Compiler
    • Fortran 2008 SUBMODULE support
    • Assignments to allocatable variables changed to match Fortran 2003 semantics on both host and device
    • When using LLVM, debug metadata generated for module variables
    • Free-form source lines can now be up to 1000 characters
    • All Fortran CHARACTER entities now 64-bit integers
  • OpenMP 4.5 (LLVM code generator only)
    • Improved efficiency of combined "distribute parallel" loop constructs
    • DWARF debug information for OpenMP thread private variables
  • Utilities
    • Changed the output of the pgaccelinfo utility
    • Changed the output of the pgcpuid utility
  • Deprecations and Eliminations
    • Dropped support for NVIDIA Fermi GPUs
    • Last release to include bundled Microsoft toolchain components
  • Plus 33 user-requested enhancements and fixes

PGI 2018 version 18.5 (released May 31, 2018)

  • CUDA Toolkit — Added full support for CUDA 9.2; use the cuda9.2 sub-option with the -⁠ta=tesla or -⁠Mcuda compiler options to compile and link with the integrated CUDA 9.2 toolkit components.
  • Added support for Xcode 9.3 on macOS.
  • Improved function offset information in runtime tracebacks in optimized (non-debug) modes.
  • Plus 10 user-requested enhancements and fixes

PGI 2018 version 18.4 (released April 26, 2018)

  • PGI Community Edition release.
  • PGI Accelerator Compilers — Added support for CUDA 9.2 if one directs the compiler to a valid installation location of CUDA 9.2 using CUDA_HOME.
  • PGI Fortran
    • Added support for internal procedures, assigned procedure pointers and internal procedures passed as actual arguments to procedure dummy arguments.
    • Added support for intrinsics SCALE, MAXVAL, MINVAL, MAXLOC and MINLOC in initializers.
  • Plus 20 user-requested enhancements and fixes
