Ruby Weekly issue 804 covers several notable updates: Ruby core team member Shugo Maeda has implemented block-level refinements via Proc#with_refinements; Rails ERD 2.0 has been revived, now using Mermaid instead of Graphviz for generating entity-relationship diagrams from Rails models; RubyLLM 1.16 adds concurrent tool execution, ActiveSupport::Notifications events, and custom API endpoints. Experimental community submissions include Ruby bindings for Apple's Foundation Models, a new statically-typed language called Jo that compiles to Ruby and Python, a minimalist agentic coding harness in Ruby, Fish-like autosuggestions for irb, a fake HTTP server for RSpec, and Graphviz bindings for mruby.
