March 2025 focused on deprecating the OpenSearch DSL JSON response format in the OpenSearch SQL plugin and removing the JSON format option from request handling. This aligns the repo with the v3.0.0 deprecation plan and reduces API surface area for maintainers and downstream clients. The change is tracked in commit f750bc67267ee8bc3e4aa5f554dcfd78649c6065, which includes the message "[v3.0.0] Deprecate OpenSearch DSL format (#3367)". In support of this transition, integration tests that rely on the JSON format were skipped in the active pipeline to avoid false failures while the deprecation path is enacted. Overall, this work improves maintainability, clarifies the API surface for customers, and positions the SQL plugin for a cleaner, more stable release.
