A new Ruby blog post/announcement has been posted!

We are pleased to announce the release of Ruby 4.0.0-preview3. Ruby 4.0 introduces Ruby::BOX and “ZJIT”, and adds many improvements.

Ruby::BOX

A new (experimental) feature to provide separation about definitions. For the detail of “Ruby Box”, see doc/language/box.md. [Feature #21311] [Misc #21385]

Language changes

• *nil no longer calls nil.to_a, similar to how **nil does not call nil.to_hash. [Feature #21047]

• Logical binary operators (||, &&, and and or) at the beginning of a line continue the previous line, like fluent dot. The following two code are equal:

  <span class="o">...</span>
  

  end
