Ruby 3.4 released
Continuing its tradition of yearly major releases on December 25, the Ruby programming-language project has released Ruby 3.4.0 (followed quickly by 3.4.1, which simply updates the version number). Ruby 3.4 includes lots of changes, including the addition of it as a less-confusing shorthand for _1 as a block parameter, switching to Prism as the default parser, adding the Happy Eyeballs version 2 algorithm to the socket library, just-in-time (JIT) compiler (YJIT) improvements, garbage-collection modularization, and more.
