+ Provided updated ChangeLog notes, information in `Release.cc`, updated version
  numbers in `CMakeLists.txt`.
+ The logic used to set the "patch" digit (third digit) of the version wasn't
  working correctly and needed to be fixed.  Normally, the "patch" value is the
  configure date.  The release scripts use special logic to force this value to
  a specific integral value (usually "0").
+ Update the `*-env.sh` scripts to supported requested toolchains for this
  release:
  - gcc/7.4.0 instead of gcc/6.4.0
  - intel/18.0.2
  - attempted intel/17.0.4 but the release failed due to a compiler bug.
  - For ATS-1, force unload the hugepages module.
