"I was looking at Thorium the other day, but if you look at their releases they’re consistently far behind. The current release is 117 from a week ago, despite 118 being released to stable 2 weeks ago and 117 being released to stable a month ago.

This is quite bad because it means it received the major WebP vulnerability fix nearly a month late for example."
