PGI 2018 version 18.7 (released August 16, 2018)
- PGI Accelerator Features and Enhancements
- OpenACC 3.0 true deep copy directives for aggregate data structures in Fortran, C and C++
- PGI Compiler Assisted Software Testing (PCAST) can detect when results diverge between CPU and GPU code versions
- Default CUDA version now matches installed CUDA Driver

- 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
- Improved efficiency of combined "distribute parallel" loop constructs
- DWARF debug information for OpenMP thread private variables
- Changed the output of the pgaccelinfo utility
- Changed the output of the pgcpuid utility
- Dropped support for NVIDIA Fermi GPUs
- Last release to include bundled Microsoft toolchain components
PGI 2018 version 18.5 (released May 31, 2018)

- 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
