217 Plus
has been developed by former RAC, now RiAC, who owned the Mil-HDBK-217 standard
in the past. 217 Plus is the successor of PRISM and was released in 2006. As of 2022, 217 Plus-2015 Notice 2 from 2017 is the current version. The name 217 Plus was chosen for marketing purposes in order to replace Mil-HDBK-217, which was already quite dated at that time. However this strategy has terribly failed. As of 2022, 217 Plus is still only rarely used. |
