In this issue, the Concurrency Column, which I have the honour of co-editing, features two outstanding contributions:

• “Decision Problems for Global Protocol Specifications” by Elaine Li
• “Typing Scalas-Yoshida Benchmarks” by Franco Barbanera, Mariangiola Dezani-Ciancaglini, and Ugo de’Liguoro

A huge thank you to the authors for their high-quality work, providing invaluable insights for both theoretical research and practical foundational frameworks in concurrent and distributed systems.

You can freely access and download the full issue and the individual columns here.
