October 2025 for ethdk (ethlete-io/ethdk): Focused on accelerating the platform migration through migration tooling, dependency modernization, and codebase stabilization. Key work includes migrating QueryClient to ExperimentalQuery with updated naming, strengthening migration infrastructure (dependency scanning, inject function generation, and extraInjectionToken), laying groundwork for CDK v5 migration, and extensive refactoring to improve readability, testing, and build hygiene. These changes reduce technical debt, improve compatibility with Angular ecosystem, and enhance developer velocity for future migrations. Major lockfile updates and Angular peer dependency upgrades further stabilize the baseline and reduce integration risk.
