Jul 1, 2025July 2025 monthly summary for ansible-collections/ibm_zos_core: Implemented volume definition support in the zos_mvs_raw module to allow precise DD statements with volume metadata (volume name, unit, disposition). Updated module arguments and data definition models, and added comprehensive functional tests to validate end-to-end behavior. This enhancement expands automation capability for IBM Z data definitions, reduces manual steps, and improves reliability in production deployments.

Jun 1, 2025June 2025: Stability and security hygiene improvements in ansible-collections/ibm_zos_core, focusing on zos_lineinfile module reliability and safer static analysis posture. Delivered a bug fix to guarantee return_content and backup_name presence in module responses, tightened output/logging reliability, and added a clarifying comment to address a Bandit warning (non-security-critical). These changes reduce troubleshooting time and improve automation reliability for IBM Z environments.

Apr 1, 2025April 2025 monthly summary for ansible-collections/ibm_zos_core. Key features delivered include returning backup_name in zos_backup_restore outputs and documenting the return values, plus tests validating backup_name across success scenarios; improved multi-volume handling in zos_data_set to prevent creation when a dataset with the same name is cataloged on a different volume, removal of outdated validation now handled upstream, and corresponding changelog/docs updates. These changes enhance the reliability of backups/restores, ensure safer multi-volume dataset management, and align with upstream behavior for maintainability.
