Ada 202x Language Reference Manual

The documents on this page consolidate possible corrections and improvements to the Ada Standard (International Standard ISO/IEC 8652:202x). The corrections and improvements will be produced by the ISO/IEC JTC 1/SC 22/WG 9 Ada Rapporteur Group (ARG), and are known as "Ada 202x". The corrections include those published in Technical Corrigendum 1 (ISO/IEC 8652:2012/Cor 1:2016). Additional corrections and improvements are expected for Ada 202x; the timing and form (Corrigendum, Amendment, Revision) of future improvements has not yet been determined. Additionally, whether standardization will succeed is unknown. Thus, any proposed correction or feature may be substantially changed or withdrawn before an updated language completes standardization. These draft documents are not an official publication or work product of the ARG, but rather are provided by the ARA as a service to the Ada community.
The consolidated Ada 2012 standard (including TC1) is available here. The original (Ada 2012) standard is available here.
This is draft 10. This draft contains all ARG-approved AI12s that were approved through the end of 2016.
