Ruby 2.4

Ruby 2.4 is the latest stable version of Ruby. Many new features and improvements are included, for example:

  • hash table improvements

  • unify Fixnum and Bignum into Integer

  • String supports Unicode case mappings

  • performance and debugging improvements

Ruby 2.4 includes updates to soname and so Ruby packages that use binary extensions should be rebuilt. Nevertheless, since the Ruby community paid great attention to source compatibility, no changes to your code are needed.

More information about Ruby 2.4 can be found in the Ruby community’s Ruby 2.4.0 Release Notes.
