October 2025: Delivered a critical correctness fix for Snowflake dialect in PRQL/prql, ensuring SQL identifiers are always quoted to preserve case-sensitivity, and added cross-dialect tests to validate behavior. This reduces risky implicit-casing errors for Snowflake users and strengthens the generated SQL's compatibility with Snowflake's quoting rules. The change was implemented as a targeted bug fix (commit 17d7c513388eb0b04ec5c86af467375626e40512) and aligns with our commitment to reliable cross-dialect SQL generation and robust test coverage.

July 2025 monthly summary for PRQL/prql: Implemented a targeted bug fix that optimizes SQL generation by avoiding an unnecessary GROUP BY when sorting precedes aggregation. This improves correctness and efficiency of generated queries and reduces overhead on large datasets. Work focused on conditional sort-column collection in get_requirements.
