Extended functionality of ``HLoc`` selections in ``IndexHierarchy`` to properly handle selection lists, Boolean arrays, and nested ``ILoc`` selections.

Corrected issue in ``Frame.from_concat`` whereby, when given inputs with ``IndexHierarchy``, ``IndexHierarchy`` were not returned.

Extended ``name`` propagation to applications of binary operators where an opperand is a scalar.

Binary operators now work with ``Frame`` and same-shaped NumPy arrays.

Extended support for step arguments in ``loc`` interfaces.

Implemented ``Frame.join_left``, ``Frame.join_right``, ``Frame.join_inner``, and ``Frame.join_outer``.

Implemented ``Frame.insert_before``, ``Frame.insert_after``.

Implemented ``Series.insert_before``, ``Series.insert_after``.

``IndexHierarchy.from_labels`` now enforces all labels to have the same depth.

Fixed issue where, when passing an array to ``Frame.from_records``, the ``name`` parameter is not passed to the constructor.

Implemented ``equals()`` methods on all containers.

Added defensive check against assigning a Pandas Series to a FrameGO as an unlabeled iterator.

Added proper handling of types multiple-inherited from ``str`` (or any other type) and ``Enum``.

Implemented support for operator overloading of addition and multiplication on string dtypes.

Implemented ``via_str`` and ``via_dt`` accesors on all ``ContainerOperand``.

When writing to XLSX, the shape of the ``Frame`` is validated to fit within the limits of XLSX sheets.

Added support for ``round()`` on ``Frame``.

Added ``name`` parameter to all methods of ``IterNodeDelegate`` that produce a new container, including ``map_any()``, ``map_fill()``, ``map_all()``, ``apply()``, and ``apply_pool()``.

Support for ``include_index`` and ``include_columns`` in ``DisplayConfig`` instances and ``Display`` output.

Performance improvements to iterating tuples from ``IndexHierarchy``.

Performance improvements for ``IndexHierarchy`` transformations, including adding or dropping levels and rehierarch.
