ADA 2022 Documents
The documents on this page describe the 2022 amendments to the ADA standard, commonly known as ADA 2022. Amendments to ISO/IEC JTC 1/SC 22/WG 9 were prepared by the Ada Rapporteur Group (ARG), and are published as international standard ISO/IEC 8652:2023(e). The document used as source material for the standard is known as the ADA Reference Manual. Related documents are also found on this page.
Older versions of the Ada standard, including the (now replaced) Ada 2012 Consolidated Standard, can be found here.
