May 2025 monthly summary: Delivered key enhancements, safety fixes, and improved usability across the IBM ICD Terraform modules. Key items include Secrets Manager naming standardization and test configuration in MySQL and MongoDB modules (renames such as skip_mysql_sm_auth_policy -> skip_mysql_secrets_manager_auth_policy; admin_pass_secret_manager_secret_group/name -> admin_pass_secrets_manager_secret_group; test prefix-based secret group naming). Added PITR cross-field validation to prevent incomplete configurations. Expanded developer guidance and usage examples to support registry-based consumption across MySQL, MongoDB, Redis, RabbitMQ, MQ Cloud, and Elasticsearch modules. Upgraded dependencies for MQ Cloud to Terraform >=1.9.0 and IBM provider >=1.78.1,<2.0.0 to improve compatibility and stability. Updated RabbitMQ module to drop support for 3.9 and 3.12 and add 4.0 support. These changes improve maintainability, reduce misconfiguration risk, and accelerate customer adoption by clarifying variable names, improving tests, and facilitating module sourcing from registries.
