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.
