Apr 1, 2025April 2025 focused on hardening asset processing accuracy in cloudoperators/heureka. Implemented a bug fix to correctly group pods by their controlling resource (e.g., Jobs and other replica sets) and updated the underlying data structures and aggregation logic to reflect pod sets and container-level information, resulting in more reliable asset inventories and reporting. The change also addresses cronjob grouping to ensure correct asset classification across resource types.
