Jul 1, 2025July 2025 monthly summary for gruntwork-io/terragrunt: Delivered core feature enhancements and reliability improvements through a Runner Pool overhaul for concurrent execution and destroy testing, expanded configuration flexibility with custom discovery filenames and mixed config parsing, and extended cloud-nuke cleanup to include DynamoDB resources. Roadmap documentation was improved around terragrunt.values.hcl defaults and fail-fast behavior; and ongoing maintenance included dependency updates to stay aligned with security patches. These changes collectively reduce run time via parallelism, strengthen cleanup guarantees, and improve developer experience through clearer docs and up-to-date tooling.
