January 2025 focused on correcting critical admin discovery logic in crate/crate-operator, strengthening test coverage for grand-central enablement, and completing release readiness for 2.43.1. Delivered a precise fix to the get_cluster_admin_username to exclude the grand-central admin when GC is enabled, updated tests for GC-enabled and GC-disabled scenarios, and prepped the release with version bumps across multiple charts and changelog entries. These efforts improve reliability of admin discovery, reduce risk in upgrades, and accelerate upcoming deployments.
