Released on 2023-09-25

* Use 'ravel' and 'wind' as antonyms instead of 'ravel' and 'unravel'.
  English is weird. 'Ravel' and 'unravel' mean the same thing!.
  (:pr:`100`, :pr:`104`).
* Added new :class:`emsarray.conventions.DimensionConvention` subclass.
  For conventions with multiple grids defined on unique subsets of dimensions
  this base class will provide a number of default method implementations.
  All existing conventions have been updated to build off this base class.
  (:pr:`100`)
* Remove workaround for `pydata/xarray#6049 <https://github.com/pydata/xarray/pull/6049>`_ (:pr:`101`).
* Add :meth:`.Convention.wind()` method as the inverse to :meth:`.Convention.ravel()`
  (:pr:`102`, :pr:`104`).
* Add :attr:`.Convention.strtree()` spatial index,
  deprecate :attr:`.Convention.spatial_index()`.
  The old attribute was a compatibility shim around Shapely 1.8.x STRtree implementation.
  Now that the minimum version of Shapely is 2.0, the STRtree can be used directly.
  (:pr:`103`).
* Add :meth:`emsarray.plot.add_landmarks()`
  and `landmarks` parameter to :meth:`Convention.plot` and related functions.
  (:pr:`107`).
* Make the `positive_down` and `deep_to_shallow` parameters optional
  for :func:`~emsarray.operations.depth.normalize_depth_variables`.
  If not supplied, that feature of the depth variable is not normalized.
  This is a breaking change if you previously relied
  on the default value of `True` for these parameters.
  (:pr:`108`).
* Add new module :mod:`emsarray.transect` for making transect plots.
  This feature is considered experimental
  and may change significantly in future releases.
  (:pr:`110`).
* Fix an issue with plotting variables with no ``long_name`` attribute.
  (:issue:`105`, :pr:`111`).
