This is a new release with some changes under the bonnet and some new features:
Started to include Apptainer in the mix
CentOS-8 removed as End Of Life
EasyBuild bumped to version 4.5.3 as version 4.5.2 had an issue
some minor tidying up of the code.
Please note: We still found some issues for Rocky-8 and `envmod` for Singularity 3.8.x.
For that reason, we currently suggest to use the 3.7.x branch instead until we hopefully
sorted the problem out in the next release.
