Breaking changes
~~~~~~~~~~~~~~~~

.. warning::
  - The ``pyspark`` package is no longer included by default, so only the spark-connect connection will works by default.
    If you want to keep using other spark connection types you must install the airflow spark provider
    with the  ``pyspark`` extra

    example: ``apache-airflow-providers-apache-spark[pyspark]==X.Y.Z``

    Because the package ``pyspark`` is more than 400mb and is not necessary if only using spark-connect to trigger a job

  - The minimum pyspark and spark-connect version is now 4.0.0

* ``[breaking] Make pyspark-client as default and  pyspark package optional (#60031)``

Breaking changes
~~~~~~~~~~~~~~~~

.. warning::
  All deprecated classes, parameters and features have been removed from the Apache Spark provider package.
  The following breaking changes were introduced:

  * Operators

    * Removed ``_sql()`` support for SparkSqlOperator. Please use ``sql`` attribute instead. ``_sql`` was
      introduced in 2016 and since it was listed as templated field, which is no longer the case, we
      handled it as public api despite the ``_`` prefix that marked it as private.

Breaking changes
~~~~~~~~~~~~~~~~

The ``spark-binary`` connection extra could be set to any binary, but with 4.0.0 version only two values
are allowed for it ``spark-submit`` and ``spark2-submit``.

The ``spark-home`` connection extra is not allowed anymore - the binary should be available on the
PATH in order to use SparkSubmitHook and SparkSubmitOperator.

Breaking changes
~~~~~~~~~~~~~~~~

* ``Auto-apply apply_default decorator (#15667)``

.. warning:: Due to apply_default decorator removal, this version of the provider requires Airflow 2.1.0+.
   If your Airflow version is < 2.1.0, and you want to install this provider version, first upgrade
   Airflow to at least version 2.1.0. Otherwise your Airflow package version will be upgraded
   automatically and you will have to manually run ``airflow upgrade db`` to complete the migration.
