DataSHIELD v5.0.0 has now been released. This is a breaking change in DataSHIELD as there are significant changes to functions, structure of packages, the version of R (and likely other stuff). Existing DataSHIELD users may need to be upgraded and your existing analysis scripts due to syntax and library changes in DataSHIELD v5.0.0 once your consortium has upgraded to this version.
DataSHIELD v5.0.0 Release notes are available in addition to updated tutorials/training on the DataSHIELD wiki.
