In 2004, software was renamed to Open Cascade Technology in order to distinguish it from the name of the company itself.

Open Cascade S.A.S. provides a certified version of the library, which is released sporadically, usually 1–2 releases per year.<ref>{{cite web|url=https://dev.opencascade.org/release/previous/|title=OCCT Previous Releases}}</ref> Until version 6.5.0 (2011), only minor and major versions were publicly available, while intermediate (maintenance) releases were accessible only to customers of Open Cascade S.A.S. For example, version 6.3.0 was publicly released in 2008, and the next public version 6.5.0 was released in early 2011. All recent releases starting from version 6.5.0 are public.<ref>{{cite web|url=http://www.opencascade.org/about/news/issue173/|title=Becoming more and more open!|access-date=21 June 2011|archive-date=19 June 2011|archive-url=https://web.archive.org/web/20110619015005/http://www.opencascade.org/about/news/issue173/|url-status=dead}}</ref>
