Monthly Merge Report for OSS projects: November 2025

November saw significant advancements across three key open-source projects: SQLMesh, SQLGlot, and the Fivetran Connector SDK. SQLMesh focused on enhancing reliability and compatibility, notably with its v0.209.4 release, which improved dbt compatibility and introduced MERGE support for the Fabric engine. SQLGlot made substantial progress with 125 merged pull requests aimed at enhancing dialect fidelity and type-aware analytics, particularly benefiting platforms like DuckDB and Snowflake. Meanwhile, the Fivetran Connector SDK experienced a hackathon-driven expansion with 30 new pull requests that contributed to a broad range of new connector examples and improved developer experiences. These projects reflect ongoing collaboration and innovation, with improvements enhancing capabilities for those involved in dbt projects, SQL transpiling, and custom data connectors. Looking forward, December is expected to continue these development themes, focusing on dbt and engine refinements, semantic and dialect advancements in SQLGlot, and further connector expansion and platform enhancements in the Fivetran Connector SDK.
