Release notes for 4.0 (kirkstone)
---------------------------------

This is a Long Term Support release, published in April 2022, and supported at least for two years (April 2024).

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 :ref:`ref-classes-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 = "hashserv.yocto.io:8687"
     SSTATE_MIRRORS ?= "file://.* https://sstate.yoctoproject.org/all/PATH;downloadfilename=PATH"

- The Python package build process is now based on `wheels <https://pythonwheels.com/>`__
  in line with the upstream direction.

- New :ref:`ref-classes-overlayfs` and :ref:`ref-classes-overlayfs-etc` classes and
  ``overlayroot`` support in the :term:`Initramfs` framework to make it easier to
  overlay read-only filesystems (for example) with
  :wikipedia:`OverlayFS <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 :term:`LICENSE` values set by recipes:

* cmake: add BSD-1-Clause & MIT & BSD-2-Clause to :term:`LICENSE` due to additional vendored libraries in native/target context
* gettext: extend :term:`LICENSE` conditional upon :term:`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 :term:`LIC_FILES_CHKSUM` if pam is enabled
* libidn2: add Unicode-DFS-2016 license
* libsdl2: add BSD-2-Clause to :term:`LICENSE` due to default yuv2rgb and hidapi inclusion
* libx11-compose-data: update :term:`LICENSE` to "MIT & MIT-style & BSD-1-Clause & HPND & HPND-sell-variant" to better reflect reality
* libx11: update :term:`LICENSE` to "MIT & MIT-style & BSD-1-Clause & HPND & HPND-sell-variant" to better reflect reality
* libxshmfence: correct :term:`LICENSE` - MIT -> HPND
* newlib: add BSD-3-Clause to :term:`LICENSE`
* python3-idna: correct :term:`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 :term:`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.
