New software stack (2021-nov)

On the 1 st of April 2022 the new default DCC software stack (see here if you are using it will be updated to the next release.

A lot of software has been updated. In particular the use of the zlib library has been changed to the much more performant zlib-ng. This package is used in many libraries (notably NetCDF and HDF5) and all programs using gz compressions should benefit from this.

The default compiler is now GCC 11.2.0 meaning that fortran developers should be aware of the default argument mismatch problem, please consider using -fallow-argument-mismatch if you experience problems.
