.. NOTE TO MAINTAINERS: All the Zephyr commits in the below git commands must be handled specially after each upmerge and each nRF Connect SDK release.

The Zephyr fork in |NCS| (``sdk-zephyr``) contains all commits from the upstream Zephyr repository up to and including ``ea02b93eea35afef32ebb31f49f8e79932e7deee``, with some |NCS| specific additions.

For the list of upstream Zephyr commits (not including cherry-picked commits) incorporated into nRF Connect SDK since the most recent release, run the following command from the :file:`ncs/zephyr` repository (after running ``west update``):

.. code-block:: none

   git log --oneline ea02b93eea ^23cf38934c

For the list of |NCS| specific commits, including commits cherry-picked from upstream, run:

.. code-block:: none

   git log --oneline manifest-rev ^ea02b93eea

The current |NCS| main branch is based on revision ``ea02b93eea`` of Zephyr.

.. note::
   For possible breaking changes and changes between the latest Zephyr release and the current Zephyr version, refer to the :ref:`Zephyr release notes <zephyr_release_notes>`.
