Snyk Code - Ruby 4 Support

Starting February 24, 2026, Snyk Code will begin a phased rollout of support for Ruby 4.0. This initial update focuses on foundational parser improvements and enhanced support for Ruby modules to accommodate the latest language features.

• Ruby 4.0 Parser: Support for new syntax and language features introduced in the Ruby 4.0 specification.

• Module Analysis: Improved understanding of Ruby module structures for more accurate pathing and taint flow.

Impact on Results: Because this update provides a more precise interpretation of Ruby codebases, customers may see an increase in findings as the engine identifies issues that were previously outside the parser's scope.

This release is the first in a series of planned enhancements to our Ruby analysis engine scheduled for the first half of 2026. We will continue to announce significant updates and further improvements in this area as they are rolled out.

This update will be automatically available to all customers using Snyk Code for Ruby.
