Ruby 3.3 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 related to performance optimizations, parser, and JIT that happened in 3.3 (which is, on the other hand, somewhat lighter on the “small quality of life improvement” changes). The changes aren’t covered 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.
