+
+Increased minimum versions for dependencies
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Some minimum supported versions of dependencies were updated.
+If installed, we now require:
+
++-----------------+-----------------+----------+---------+
+| Package         | Minimum Version | Required | Changed |
++=================+=================+==========+=========+
+| mypy (dev)      | 0.931           |          |    X    |
++-----------------+-----------------+----------+---------+
+
+
+For `optional libraries <https://pandas.pydata.org/docs/getting_started/install.html>`_ the general recommendation is to use the latest version.
+The following table lists the lowest version per library that is currently being tested throughout the development of pandas.
+Optional libraries below the lowest tested version may still work, but are not considered supported.
+
++-----------------+-----------------+---------+
+| Package         | Minimum Version | Changed |

+|                 |                 |    X    |

+.. _whatsnew_150.read_xml_dtypes:
+
+read_xml now supports ``dtype``, ``converters``, and ``parse_dates``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Similar to other IO methods, :func:`pandas.read_xml` now supports assigning specific dtypes to columns,
+apply converter methods, and parse dates (:issue:`43567`).
+
+.. ipython:: python
+
+    xml_dates = """<?xml version='1.0' encoding='utf-8'?>
+    <data>
+      <row>
+        <shape>square</shape>

+.. _whatsnew_150.deprecations:
+
+Deprecations
+~~~~~~~~~~~~
+
+.. _whatsnew_150.deprecations.int_slicing_series:
+
+In a future version, integer slicing on a :class:`Series` with a :class:`Int64Index` or :class:`RangeIndex` will be treated as *label-based*, not positional. This will make the behavior consistent with other :meth:`Series.__getitem__` and :meth:`Series.__setitem__` behaviors (:issue:`45162`).
+
+For example:
+
+.. ipython:: python
+
+   ser = pd.Series([1, 2, 3, 4, 5], index=[2, 3, 5, 7, 11])
+
+In the old behavior, ``ser[2:4]`` treats the slice as positional:
+
+*Old behavior*:
+
+.. code-block:: ipython
+
+    In [3]: ser[2:4]
+    Out[3]:
+    5    3
+    7    4
+    dtype: int64
+
+In a future version, this will be treated as label-based:
+
+*Future behavior*:
+
+.. code-block:: ipython
+
+    In [4]: ser.loc[2:4]
+    Out[4]:
+    2    1
+    3    2
+    dtype: int64
+
+To retain the old behavior, use ``series.iloc[i:j]``. To get the future behavior,
+use ``series.loc[i:j]``.
+
+Slicing on a :class:`DataFrame` will not be affected.
+
+.. _whatsnew_150.deprecations.other:
+
+Other Deprecations
+^^^^^^^^^^^^^^^^^^
+- Deprecated the keyword ``line_terminator`` in :meth:`DataFrame.to_csv` and :meth:`Series.to_csv`, use ``lineterminator`` instead; this is for consistency with :func:`read_csv` and the standard library 'csv' module (:issue:`9568`)
+- Deprecated behavior of :meth:`SparseArray.astype`, :meth:`Series.astype`, and :meth:`DataFrame.astype` with :class:`SparseDtype` when passing a non-sparse ``dtype``. In a future version, this will cast to that non-sparse dtype instead of wrapping it in a :class:`SparseDtype` (:issue:`34457`)
+- Deprecated behavior of :meth:`DatetimeIndex.intersection` and :meth:`DatetimeIndex.symmetric_difference` (``union`` behavior was already deprecated in version 1.3.0) with mixed timezones; in a future version both will be cast to UTC instead of object dtype (:issue:`39328`, :issue:`45357`)
+- Deprecated :meth:`DataFrame.iteritems`, :meth:`Series.iteritems`, :meth:`HDFStore.iteritems` in favor of :meth:`DataFrame.items`, :meth:`Series.items`, :meth:`HDFStore.items`  (:issue:`45321`)
+- Deprecated :meth:`Series.is_monotonic` and :meth:`Index.is_monotonic` in favor of :meth:`Series.is_monotonic_increasing` and :meth:`Index.is_monotonic_increasing` (:issue:`45422`, :issue:`21335`)
+- Deprecated the ``__array_wrap__`` method of DataFrame and Series, rely on standard numpy ufuncs instead (:issue:`45451`)
+-
+
+
+.. ---------------------------------------------------------------------------
+.. _whatsnew_150.performance:
+
+Performance improvements
+~~~~~~~~~~~~~~~~~~~~~~~~
+- Performance improvement in :meth:`.GroupBy.transform` for some user-defined DataFrame -> Series functions (:issue:`45387`)
+- Performance improvement in :meth:`DataFrame.duplicated` when subset consists of only one column (:issue:`45236`)
+-
+
+.. ---------------------------------------------------------------------------
+.. _whatsnew_150.bug_fixes:
+
+Bug fixes
+~~~~~~~~~
+
+Categorical
+^^^^^^^^^^^
+- Bug in :meth:`CategoricalIndex.union` when the index's categories are integer-dtype and the index contains ``NaN`` values incorrectly raising instead of casting to ``float64`` (:issue:`45362`)
+-
+
+Datetimelike
+^^^^^^^^^^^^
+- Bug in :meth:`DataFrame.quantile` with datetime-like dtypes and no rows incorrectly returning ``float64`` dtype instead of retaining datetime-like dtype (:issue:`41544`)

+^^^^^^^^^
+-
+
+Timezones
+^^^^^^^^^
+-
+-
+
+Numeric
+^^^^^^^

+-
+
+Conversion
+^^^^^^^^^^
+- Bug in :meth:`DataFrame.astype` not preserving subclasses (:issue:`40810`)
+- Bug in constructing a :class:`Series` from a float-containing list or a floating-dtype ndarray-like (e.g. ``dask.Array``) and an integer dtype raising instead of casting like we would with an ``np.ndarray`` (:issue:`40110`)
+- Bug in :meth:`Float64Index.astype` to unsigned integer dtype incorrectly casting to ``np.int64`` dtype (:issue:`45309`)
+- Bug in :meth:`Series.astype` and :meth:`DataFrame.astype` from floating dtype to unsigned integer dtype failing to raise in the presence of negative values (:issue:`45151`)
+- Bug in :func:`array` with ``FloatingDtype`` and values containing float-castable strings incorrectly raising (:issue:`45424`)
+-
+
+Strings
+^^^^^^^
+-
+-
+
+Interval
+^^^^^^^^
+- Bug in :meth:`IntervalArray.__setitem__` when setting ``np.nan`` into an integer-backed array raising ``ValueError`` instead of ``TypeError`` (:issue:`45484`)
+-
+
+Indexing
+^^^^^^^^
+- Bug in :meth:`loc.__getitem__` with a list of keys causing an internal inconsistency that could lead to a disconnect between ``frame.at[x, y]`` vs ``frame[y].loc[x]`` (:issue:`22372`)
+- Bug in :meth:`DataFrame.iloc` where indexing a single row on a :class:`DataFrame` with a single ExtensionDtype column gave a copy instead of a view on the underlying data (:issue:`45241`)
+- Bug in :meth:`Series.__setitem__` with a non-integer :class:`Index` when using an integer key to set a value that cannot be set inplace where a ``ValueError`` was raised insead of casting to a common dtype (:issue:`45070`)
+- Bug when setting a value too large for a :class:`Series` dtype failing to coerce to a common type (:issue:`26049`, :issue:`32878`)
+- Bug in :meth:`loc.__setitem__` treating ``range`` keys as positional instead of label-based (:issue:`45479`)
+- Bug in :meth:`Series.__setitem__` when setting ``boolean`` dtype values containing ``NA`` incorrectly raising instead of casting to ``boolean`` dtype (:issue:`45462`)
+- Bug in :meth:`Series.__setitem__` where setting :attr:`NA` into a numeric-dtpye :class:`Series` would incorrectly upcast to object-dtype rather than treating the value as ``np.nan`` (:issue:`44199`)
+- Bug in getting a column from a DataFrame with an object-dtype row index with datetime-like values: the resulting Series now preserves the exact object-dtype Index from the parent DataFrame (:issue:`42950`)

+
+Missing
+^^^^^^^
+-
+-
+
+MultiIndex
+^^^^^^^^^^
+-
+-
+
+I/O

+- Bug in :meth:`DataFrame.info` where a new line at the end of the output is omitted when called on an empty :class:`DataFrame` (:issue:`45494`)
+- Bug in :func:`read_parquet` when ``engine="pyarrow"`` which caused partial write to disk when column of unsupported datatype was passed (:issue:`44914`)
+-
+
+Period
+^^^^^^
+-
+-
+
+Plotting
+^^^^^^^^
+- Bug in :meth:`DataFrame.plot.barh` that prevented labeling the x-axis and ``xlabel`` updating the y-axis label (:issue:`45144`)

+- Bug in :meth:`DataFrame.boxplot` that prevented passing in ``xlabel`` and ``ylabel`` (:issue:`45463`)
+- Bug in :meth:`DataFrame.boxplot` that prevented specifying ``vert=False`` (:issue:`36918`)
+- The function :meth:`DataFrame.scatter` now accepts ``color`` as an alias for ``c`` and ``size`` as an alias for ``s`` for consistency to other plotting functions (:issue:`44670`)

+
+Groupby/resample/rolling
+^^^^^^^^^^^^^^^^^^^^^^^^
+- Bug in :meth:`DataFrame.resample` ignoring ``closed="right"`` on :class:`TimedeltaIndex` (:issue:`45414`)
+-
+
+Reshaping
+^^^^^^^^^

+-
+
+Sparse
+^^^^^^
+-
+-
+
+ExtensionArray
+^^^^^^^^^^^^^^
+- Bug in :meth:`IntegerArray.searchsorted` and :meth:`FloatingArray.searchsorted` returning inconsistent results when acting on ``np.nan`` (:issue:`45255`)
