Tina M's News from the YAML world talk was enlightening about the (previously?) sorry state of YAML modules and current improvements (to YAML::PP module(s)).
Paul E's On the Road to 2025 presentation was very noisy, along with others' interruptions in form of keyboard clatter and such, to bear😣.

Perhaps recorded videos might have allowed more legible/not-fuzzy text; reduced the broken up audio, noise/interruptions🤷♂️.
