Updated tests and documentation to reflect the new integration, accelerating onboarding and lowering risk during adoption. Improved CI/CD and overall code quality through targeted PR hygiene and workflow enhancements. Strengthened public APIs to support manual handling where needed (AddElasticVue made public) and scoped WithElasticVue to the current Elasticsearch resource to prevent unintended configuration changes.

June 2025 focused on improving documentation accuracy for the Umbraco extension API. Corrected the ManifestBase.weight JSDoc to reflect that higher weight places extensions earlier, aligning docs with code behavior (commit ce2756f399ef7c7b78ef5bc047f5439698f181bb). No features were shipped this month; this work improves developer onboarding and reduces misconfigurations by clarifying API semantics and ensuring documentation consistency.
