 ### Fixed
 - Fixed Cython 3.3 compatibility (#1248)

+- Fixed warnings present in parallel tests execution
 ### Changed
 - Move magic methods (`__radd__`, `__sub__`, `__rsub__`, `__rmul__`, `__richcmp__`, `__neg__`, and `__rtruediv__`) to `ExprLike` base class (#1204)
 - Speed up `Expr.__add__` and `Expr.__iadd__` via the C-level API (#1205)
