Ruby 3.2.0 Preview 1 Released — Sure, 3.2 isn’t due till Christmas, but Christmas has come early in the shape of the first preview release. What’s new? A timeout feature for regular expressions, WebAssembly support (as long as your code isn’t relying on threads..), and third party sources will no longer be bundled (bye libyaml and libffi – this may make installation trickier on some platforms). Find patterns are no longer considered experimental, too.
