Ada 2012 is the latest version of the international standard for the
programming language Ada. It is designated ISO/IEC 8652:2012 (E) and is
a new edition replacing the 2005 version. The primary goals for the new
version were to further enhance its capabilities particularly in those
areas where its reliability and predictability are of great value. Many
important new features have been included such as those defining dynamic
contracts and for handling multiprocessors and are integrated within the
existing language framework in an elegant and coherent manner. The Ada
2012 Rationale describes not only the changes from Ada 2005 but also the
reason for the changes. It starts with an introduction providing a
general overview and this is followed by seven chapters focusing on
contracts and aspects; extended expressions; structure and visibility;
tasking and real time; iterators and pools; predefined library and
containers. The book concludes with an epilogue largely concerned with
compatibility issues.
