June 2026 — gruntwork-io/terragrunt: Delivered two major improvements focused on reliability and debugging support. The team fixed a nested list parsing bug in assume_role within codegen, ensuring proper configuration generation when transitive_tag_keys or policy_arns contain nested lists, reducing configuration errors and CI failures. We also shipped an experimental --no-hooks flag for the terragrunt run command, gated behind the optional-hooks experiment, enabling users to bypass hook execution for debugging and performance testing. In addition to delivering these features, we added regression tests for the parsing edge cases, updated the changelog, and added integration tests for the new flag. These changes improve user experience, reliability of generated configurations, and provide developers with more flexible debugging options. Key commits include fixes in codegen parsing and the experimental flag rollout.
