Ruby 3.4 changes - Ruby Changes

Note: As already explained in Introduction, this site is dedicated to changes in the language, not the implementation, therefore the list below lacks mentions of lots of important internal changes. The changes aren’t covered extensively not because they are not important, just because this site’s goals are different. See the official release notes that cover those significant internal changes. This year, though, changes are quite noticeable from the language user’s perspective, so some of them are briefly mentioned in a separate section.
