+Release notes for 4.0 (kirkstone)
+---------------------------------
+
+New Features / Enhancements in 4.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Linux kernel 5.15, glibc 2.35 and ~300 other recipe upgrades
+
+- Reproducibility: this release fixes the reproducibility issues with ``rust-llvm`` and
+  ``golang``. Recipes in OpenEmbedded-Core are now fully reproducible. Functionality
+  previously in the optional "reproducible" class has been merged into the base class.
+
+- Network access is now disabled by default for tasks other than where it is expected to ensure build integrity (where host kernel supports it)
+
+- The Yocto Project now allows you to reuse the Shared State cache from
+  its autobuilder. If the network connection between our server and your
+  machine is faster than you would build recipes from source, you can
+  try to speed up your builds by using such Shared State and Hash
+  Equivalence by setting::
+
+     BB_SIGNATURE_HANDLER = "OEEquivHash"
+     BB_HASHSERVE = "auto"
+     BB_HASHSERVE_UPSTREAM = "typhoon.yocto.io:8687"
+     SSTATE_MIRRORS ?= "file://.* https://sstate.yoctoproject.org/&YOCTO_DOC_VERSION;/PATH;downloadfilename=PATH"
+
+- The Python package build process is now based on `wheels <https://pythonwheels.com/>`__
+  in line with the upstream direction.
+
+- New :ref:`overlayfs <ref-classes-overlayfs>` and
+  :ref:`overlayfs-etc <ref-classes-overlayfs-etc>` classes and
+  ``overlayroot`` support in the initramfs framework to make it easier to
+  overlay read-only filesystems (for example) with
+  `OverlayFS <https://en.wikipedia.org/wiki/OverlayFS>`__.
+
+- Inclusive language adjustments to some variable names - see the
+  :ref:`4.0 migration guide <migration-4.0-inclusive-language>` for details.

+Known Issues in 4.0
+~~~~~~~~~~~~~~~~~~~
+
+- ``make`` version 4.2.1 is known to be buggy on non-Ubuntu systems. If this ``make``
+  version is detected on host distributions other than Ubuntu at build start time,
+  then a warning will be displayed.
+
+Recipe License changes in 4.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following corrections have been made to the LICENSE values set by recipes:
+
+* cmake: add BSD-1-Clause & MIT & BSD-2-Clause to LICENSE due to additional vendored libraries in native/target context
+* gettext: extend LICENSE conditional upon PACKAGECONFIG (due to vendored libraries)
+* gstreamer1.0: update licenses of all modules to LGPL-2.1-or-later (with some exceptions that are GPL-2.0-or-later)
+* gstreamer1.0-plugins-bad/ugly: use the GPL-2.0-or-later only when it is in use
+* kern-tools-native: add missing MIT license due to Kconfiglib
+* libcap: add pam_cap license to LIC_FILES_CHKSUM if pam is enabled
+* libidn2: add Unicode-DFS-2016 license
+* libsdl2: add BSD-2-Clause to LICENSE due to default yuv2rgb and hidapi inclusion
+* libx11-compose-data: update LICENSE to "MIT & MIT-style & BSD-1-Clause & HPND & HPND-sell-variant" to better reflect reality
+* libx11: update LICENSE to "MIT & MIT-style & BSD-1-Clause & HPND & HPND-sell-variant" to better reflect reality
+* libxshmfence: correct LICENSE - MIT -> HPND
+* newlib: add BSD-3-Clause to LICENSE
+* python3-idna: correct LICENSE - Unicode -> Unicode-TOU
+* python3-pip: add "Apache-2.0 & MPL-2.0 & LGPL-2.1-only & BSD-3-Clause & PSF-2.0 & BSD-2-Clause" to LICENSE due to vendored libraries
+
+Other license-related notes:
+
+- The ambiguous "BSD" license has been removed from the ``common-licenses`` directory.
+  Each recipe that fetches or builds BSD-licensed code should specify the proper
+  version of the BSD license in its :term:`LICENSE` value.
+
+- :term:`LICENSE` definitions now have to use `SPDX identifiers <https://spdx.org/licenses/>`__.
+  A :oe_git:`convert-spdx-licenses.py </openembedded-core/tree/scripts/contrib/convert-spdx-licenses.py>`
+  script can be used to update your recipes.
