Abstract Version 5.0 of the ORCA quantum chemistry program suite was released in July
2021. ORCA 5.0 represents a major improvement over all previous versions of ORCA and …

This short update provides an overview of the capabilities that have been added to the
ORCA electronic structure package (version 4.0) since publication of the first article in 2012 …

In this contribution to the special software-centered issue, the ORCA program package is
described. We start with a short historical perspective of how the project began and go on to …
