The OOPSLA journal of the Proceedings of the ACM on Programming Languages (PACMPL) conference welcomes papers focusing on all practical and theoretical research in programming systems, languages, and environments. Papers may address any phase of software development, including requirements, modeling, prototyping, design, implementation, generation, analysis, verification, testing, evaluation, maintenance, and reuse of software systems. Contributions may include the development of new tools, techniques, principles, and evaluations.

OOPSLA 2026 will have two rounds of review, with the first round submission deadline being October 10, 2025, and the second round submission deadline being March 17, 2026 (AoE). All deadlines are firm. New papers may be submitted to either round. Accepted papers from both rounds will be published in the PACMPL (OOPSLA) 2026 volume and invited to present at the 2026 SPLASH conference.
