As plenty of celestial catalogs and lists remain, CSOG will continue to expand and will continue to be updated for many years to come. Where applicable, information in new editions is incorporated into existing content.
After publication of CSOG 3.0 on 29 November 2024 there will not be another complete revision: from here on, new editions will be added incrementally and existing content will receive interim updates. Creation of new and updated editions is a work in progress.
