1. Introduction
In 2024-10, the C++ Library Evolution group conducted a series of electronic decision polls [P3467R0]. This paper provides the results of those polls and summarizes the results.
In total, 21 people participated in the polls. Some participants opted to not vote on some polls (lower participation was at: P2897R5, P3050R2, P3222R0, P3355R1) Thank you to everyone who participated, and to the papers' authors for all their hard work!
