July 2025: Security, reliability, and maintainability improvements for skipperator focusing on CIDR-based egress policy enforcement and configuration management. Implemented default egress policy with exceptions configured via a ConfigMap, integrated into network policy generation, preserving intra-cluster communication. Centralized CIDR config loading and parsing for SKIP features, added tests, and performed extensive code cleanup (refactors, renames, sample config updates) to improve maintainability and reliability. Fixed test CIDR ranges to reflect intended network topology. These changes reduce security risk, improve maintainability, and strengthen test coverage, enabling faster iteration and more predictable deployments.
