The Apache Calcite PMC is pleased to announce Apache Calcite release 1.41.0.

This release comes 5 months after 1.40.0, contains contributions from 41 contributors, and resolves 155 issues.

Highlights include support for several UNSIGNED types in the type system, get functional dependency metadata in RelMetadataQuery, supporting various join types on DPhyp join reorder algorithm, a new API for finding common relational sub-expressions, and new bitwise operators. Regarding this last feature, it can be possible for a certain bitwise operator and its corresponding already existing SQL function to have discrepancies on operand type checker and return type inference when unsigned parameters are involved; this shall be aligned in future versions.
