First, platform floor. Pull request 58908 bumps the minimum Ruby to version 3.3.5. The driver is a memory-safety bug — a use-after-free in older Ruby's weak map implementation described as easy to hit — which had forced Rails to limit how it uses weak maps. For developers, the impact is straightforward: if you're…
