The Proceedings of the ACM series presents high-quality research across diverse areas of computer science, as represented by the ACM Special Interest Groups (SIGs). The Proceedings of the ACM on Programming Languages (PACMPL) focuses on research on all aspects of programming languages, from design to implementation and from mathematical formalisms to empirical studies. The journal operates in close collaboration with the Special Interest Group on Programming Languages (SIGPLAN) and is committed to making high-quality peer-reviewed scientific research in programming languages free of restrictions on both access and use. This issue of PACMPL publishes 93 articles selected for OOPSLA2 2026, plus two articles from the first round. These articles represent a broad cross-section of current programming-languages research, spanning language design, verification, program analysis, compilers, systems, security, software engineering, AI for programming, and human-centered aspects of PL. Collectively, these papers reflect both the technical depth and the intellectual breadth of the community.
