06:40 PM Ruby Bug #21820: "vm_call_cfunc: cfp consistency error" occurs during rdoc generation when installing Ruby 4.0.0 via rbenv on Ubuntu 24.04

I tried setting up Ubuntu 24.04 on WSL2 (Windows 11), but still couldn't reproduce it!

05:27 PM Ruby Feature #13683: Add strict Enumerable#single

`Enumerable#sole` is a method that should only be used when the Enumerable has only one element. Using it in other cases (0 or 2+ elements) is considered a bug, or literally "exceptional", so raising an exception makes perfect sense.

12:35 PM Ruby Bug #21790 (Third Party's Issue): `Socket.getaddrinfo` hangs after `fork()` on macOS 26.1 (Tahoe) for IPv4-only hosts
