-1 There are four correctness bug fixes after RC1
- SPARK-57298: Fixed collect_set so it no longer returns duplicate NaN or -0.0 values for float and double columns, resolving a query correctness issue. - SPARK-57287: Fixed V2ExpressionSQLBuilder to correctly escape backslashes in LIKE patterns for STARTS_WITH, ENDS_WITH, and CONTAINS pushdown, preventing incorrect results from JDBC sources. - SPARK-57332: Follow-up to SPARK-57287: fixed MySQL-specific backslash escaping for LIKE predicate pushdown by adding a dialect-level string literal escaping hook. - SPARK-54876: Fixed splitSemiColon so it no longer silently drops a SQL statement that ends with a block comment.
