March 2026 focused on expanding CLI tooling and cross-platform compatibility across conda-forge repos. Delivered new Exoscale CLI recipe and Flux CLI integration, along with migration tooling enhancements for Apple Silicon (OSX ARM64) and Flux package management. These efforts improve automation, Kubernetes configuration management, and upgrade reliability while tackling platform-specific build constraints. Major bugs fixed: none reported; note that Flux Windows builds are skipped due to unavailability of kustomize on Windows. Technologies demonstrated include CLI development, build scripting, cross-platform migration tooling, and FluxCD integration.
