Since its inception, the International Real-Time Ada Workshop (IRTAW) series has provided a forum where members of the research, user, and implementer communities have singled-out issues with the real-time systems support in Ada, and explored possible solutions to them, and approaches to evolve those aspects of the language to the new frontiers of real-time computing. Over the years, the IRTAW has made important contributions to the 2005 and 2012 revisions of the Ada programming language standard, for the tasking features, the real-time and high- integrity systems annexes, the Ravenscar and the Yorvik Profiles, and – more recently – the parallel execution model of the language due to appear in the 202X revision.
