As of April 25, 2022, we have released P21 Community 4.0 to general availability! Install it now from our Downloads page.
P21C 4.0 is the first major release of this application since P21's M&A with Certara in October 2021, per the commitment that P21's software applications will “continue to be supported, updated, and developed.”

P21 is proud to announce that support for CDISC Open Rules Engine (CORE) is now available in P21 Community 4.0. We have expanded CORE’s reference implementation to let you execute machine-readable CDISC Conformance Rules within the familiar P21 toolkit. This new CDISC Engine can run from the desktop GUI or command-line interface (CLI) on any platform in which you have already installed P21 Community.
