Pandas output with `set_output` API
-----------------------------------
scikit-learn's transformers now support pandas output with the `set_output` API.
To learn more about the `set_output` API see the example:
:ref:`sphx_glr_auto_examples_miscellaneous_plot_set_output.py` and
# this `video, pandas DataFrame output for scikit-learn transformers
(some examples) <https://youtu.be/5bCg8VfX2x8>`__.

Interaction constraints in Histogram-based Gradient Boosting Trees
------------------------------------------------------------------
:class:`~ensemble.HistGradientBoostingRegressor` and
:class:`~ensemble.HistGradientBoostingClassifier` now supports interaction constraints
with the `interaction_cst` parameter. For details, see the
:ref:`User Guide <interaction_cst_hgbt>`. In the following example, features are not
allowed to interact.

Faster parser in :func:`~datasets.fetch_openml`
-----------------------------------------------
:func:`~datasets.fetch_openml` now supports a new `"pandas"` parser that is
more memory and CPU efficient. In v1.4, the default will change to
`parser="auto"` which will automatically use the `"pandas"` parser for dense
data and `"liac-arff"` for sparse data.

Experimental Array API support in :class:`~discriminant_analysis.LinearDiscriminantAnalysis`
--------------------------------------------------------------------------------------------
Experimental support for the `Array API <https://data-apis.org/array-api/latest/>`_
specification was added to :class:`~discriminant_analysis.LinearDiscriminantAnalysis`.
The estimator can now run on any Array API compliant libraries such as
`CuPy <https://docs.cupy.dev/en/stable/overview.html>`__, a GPU-accelerated array
library. For details, see the :ref:`User Guide <array_api>`.

Improved efficiency of many estimators
--------------------------------------
In version 1.1 the efficiency of many estimators relying on the computation of
pairwise distances (essentially estimators related to clustering, manifold
learning and neighbors search algorithms) was greatly improved for float64
dense input. Efficiency improvement especially were a reduced memory footprint
and a much better scalability on multi-core machines.
In version 1.2, the efficiency of these estimators was further improved for all
combinations of dense and sparse inputs on float32 and float64 datasets, except
the sparse-dense and dense-sparse combinations for the Euclidean and Squared
Euclidean Distance metrics.
A detailed list of the impacted estimators can be found in the
:ref:`changelog <release_notes_1_2>`.
