June 2025: Delivered targeted improvements for the IBM z/OS Ansible collection, focusing on documentation accuracy and automation readiness. Key changes include a documentation update for zos_copy block size when is_binary is true (block size corrected to 32720) with an accompanying changelog fragment, and an enhancement to the zos_stat module to expose explicit resource type indicators (isfile, isdataset, isaggregate, isgdg) plus an exists flag. These changes improve automation reliability, resource querying, and reduce troubleshooting time for IBM Z playbooks.

Concise monthly summary of key deliverables and impact for May 2025 across IBM z/OS collections. Highlights include a major dependency upgrade for compatibility and reliability, a new recall capability for migrated data sets, targeted bug fixes to improve security and documentation quality, and clear alignment with business value through improved stability and maintainability.

April 2025: Delivered core z/OS resource discovery enhancements and repository hygiene improvements for ansible-collections/ibm_zos_core. The team introduced the zos_stat module for retrieving facts from z/OS resources (MVS data sets, USS files, aggregates, and generation data groups) with a rich attribute set and support for multiple resource types. Added alias resolution in zos_stat, enabling querying data sets via aliases and automatic resolution to base names, accompanied by documentation. Completed repository housekeeping by removing obsolete dev tools and updating .gitignore and CI/workflows to streamline development. No critical bug fixes were recorded in this period.

March 2025 highlights across the IBM z/OS Ansible collections (ansible-collections/ibm_zos_core and IBM/z_ansible_collections_samples). Delivered reliability improvements, expanded resource discovery capabilities, and a critical bug fix, resulting in more reliable automation, clearer guidance, and stronger resource lifecycle handling for z/OS environments.

February 2025 monthly summary for ansible-collections/ibm_zos_core. Focused on enhancing zos_copy data set handling and stabilizing ASA data set copy operations. Key changes include adding a new 'large' option for dest_data_set type and fixing a bug when copying to ASA data sets with force_lock and asa_text. These changes improve flexibility, reliability, and automation capabilities for mainframe data migration tasks, with corresponding documentation updates and clean commit history.

January 2025 focused on enhancing templating flexibility and reliability in ansible-collections/ibm_zos_core. Delivered a configurable autoescape option for Jinja templates across core modules and fixed a permissions handling regression in remote script execution, reinforcing secure and predictable automation for z/OS environments.

Month: 2024-12 — Delivered two key enhancements for ansible-collections/ibm_zos_core to improve data reliability, testability, and maintainability. Focused on automated validation and robust data copy operations, aligning with business value of safer data workflows and faster feedback cycles.

November 2024: Delivered automation improvements in the IBM z/OS collection. Implemented asynchronous support for zos_job_submit to enable non-blocking job submissions, including refactoring of temporary file handling and added tests to validate the new async behavior. Hardened CI/testing for Ansible collections by addressing environment variable loading and escaping issues in tests for Ansible 2.17.1, reducing flaky test runs and improving reliability. These initiatives shorten automation run times, enhance developer productivity, and increase confidence in production automation across z/OS environments.
