On the releases side: RubyGems 4.0.17 fixes Windows path issues, RubyMine 2026.2 adds agentic debugging and Copilot integration, JRuby 10.1.1.0 brings Ruby 4.0 compatibility and CVE fixes, and Jelly UI debuts as a dependency-free Web Components library with physics animations. ## Full article daily.dev links to this article rather than hosting it.
