+======================
+
+Migration notes for 4.1 (langdale)
+-----------------------------------
+
+This section provides migration information for moving to the Yocto
+Project 4.1 Release (codename "langdale") from the prior release.
+
+
+.. _migration-4.1-make-4.0:
+
+make 4.0 is now the minimum required make version
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+glibc now requires ``make`` 4.0 to build, thus it is now the version required to
+be installed on the build host. A new ``buildtools-make-tarball`` has been
+introduced to provide just make 4.0 for host distros without a current/working
+make 4.x version; if you also need other tools you can use the updated
+``buildtools-tarball``. For more information see
+:ref:`ref-manual/system-requirements:required packages for the build host`.
+
+
+.. _migration-4.1-complementary-deps:
+
+Complementary package installation ignores recommends
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When installing complementary packages (e.g. ``-dev`` and ``-dbg`` packages when
+building an SDK, or if you have added ``dev-deps`` to :term:`IMAGE_FEATURES`),
+recommends (as defined by :term:`RRECOMMENDS`) are no longer installed.
+
+If you wish to double-check the contents of your images after this change, see
+:ref:`Checking Image / SDK Changes <migration-general-buildhistory>`. If needed
+you can explicitly install items by adding them to :term:`IMAGE_INSTALL` in
+image recipes or :term:`TOOLCHAIN_TARGET_TASK` for the SDK.
+
+
+.. _migration-4.1-dev-recommends:
+
+dev dependencies are now recommends
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default for ``${PN}-dev`` package is now to use :term:`RRECOMMENDS` instead
+of :term:`RDEPENDS` to pull in the main package. This takes advantage of a
+change to complimentary package installation to not follow :term:`RRECOMMENDS`
+(as mentioned above) and for example means an SDK for an image with both openssh
+and dropbear components will now build successfully.
+
+
+.. _migration-4.1-dropbear-sftp:
+
+dropbear now recommends openssh-sftp-server
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+openssh has switched the scp client to use the sftp protocol instead of scp to
+move files. This means scp from Fedora 36 and other current distributions will
+no longer be able to move files to/from a system running dropbear with no sftp
+server installed.
+
+The sftp server from openssh is small (200kb uncompressed) and standalone, so
+adding it to the packagegroup seems to be the best way to preserve the
+functionality for user sanity. However, if you wish to avoid this dependency,
+you can either:
+
+ A. Use ``dropbear`` in :term:`IMAGE_INSTALL` instead of
+ ``packagegroup-core-ssh-dropbear`` (or ``ssh-server-dropbear`` in
+ :term:`IMAGE_FEATURES`), or
+ B. Add ``openssh-sftp-server`` to :term:`BAD_RECOMMENDATIONS`.
+
+
+.. _migration-4.1-classes-split:
+
+Classes now split by usage context
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A split directory structure has now been set up for ``.bbclass`` files - classes
+that are intended to be inherited only by recipes (e.g. ``inherit`` in a recipe
+file, :term:`IMAGE_CLASSES` or :term:`KERNEL_CLASSES`) should be in a
+``classes-recipe`` subdirectory and classes that are intended to be inherited
+globally (e.g. via ``INHERIT +=``, :term:`PACKAGE_CLASSES`, :term:`USER_CLASSES`
+or :term:`INHERIT_DISTRO`) should be in ``classes-global``. Classes in the
+existing ``classes`` subdirectory will continue to work in any context as before.
+
+Other than knowing where to look when manually browsing the class files, this is
+not likely to require any changes to your configuration. However, if in your
+configuration you were using some classes in the incorrect context, you will now
+receive an error during parsing. For example, the following in ``local.conf`` will
+now cause an error::
+
+ INHERIT += "testimage"
+
+Since :ref:`testimage <ref-classes-testimage>` is a class intended solely to
+affect image recipes, this would be correctly specified as::
+
+ IMAGE_CLASSES += "testimage"
+
+
+.. _migration-4.1-local-file-error:
+
+Missing local files in SRC_URI now triggers an error
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a file referenced in :term:`SRC_URI` does not exist, in 4.1 this will trigger
+an error at parse time where previously this only triggered a warning. In the past
+you could ignore these warnings for example if you have multiple build
+configurations (e.g. for several different target machines) and there were recipes
+that you were not building in one of the configurations. If you have this scenario
+you will now need to conditionally add entries to :term:`SRC_URI` where they are
+valid, or use :term:`COMPATIBLE_MACHINE` / :term:`COMPATIBLE_HOST` to prevent the
+recipe from being available (and therefore avoid it being parsed) in configurations
+where the files aren't available.
+
+
+.. _migration-4.1-qa-checks:
+
+QA check changes
+~~~~~~~~~~~~~~~~
+
+- The :ref:`buildpaths <qa-check-buildpaths>` QA check is now enabled by default
+ in :term:`WARN_QA`, and thus any build system paths found in output files will
+ trigger a warning. If you see these warnings for your own recipes, for full
+ binary reproducibility you should make the necessary changes to the recipe build
+ to remove these paths. If you wish to disable the warning for a particular
+ recipe you can use :term:`INSANE_SKIP`, or for the entire build you can adjust
+ :term:`WARN_QA`. For more information, see the :ref:`buildpaths QA check
+ <qa-check-buildpaths>` section.
+
+- ``do_qa_staging`` now checks shebang length in all directories specified by
+ :term:`SYSROOT_DIRS`, since there is a maximum length defined in the kernel. For
+ native recipes which write scripts to the sysroot, if the shebang line in one of
+ these scripts is too long you will get an error. This can be skipped using
+ :term:`INSANE_SKIP` if necessary, but the best course of action is of course to
+ fix the script. There is now also a ``create_cmdline_shebang_wrapper`` function
+ that you can call e.g. from ``do_install`` (or ``do_install:append``) within a
+ recipe to create a wrapper to fix such scripts - see the ``libcheck`` recipe
+ for an example usage.
+
+
+
+Miscellaneous changes
+~~~~~~~~~~~~~~~~~~~~~
+
+- ``mount.blacklist`` has been renamed to ``mount.ignorelist`` in
+ ``udev-extraconf``. If you are customising this file via ``udev-extraconf`` then
+ you will need to update your ``udev-extraconf`` ``.bbappend`` as appropriate.
+- ``help2man-native`` has been removed from implicit sysroot dependencies. If a
+ recipe needs ``help2man-native`` it should now be explicitly added to
+ :term:`DEPENDS` within the recipe.
+- For images using systemd, the reboot watchdog timeout has been set to 60
+ seconds (from the upstream default of 10 minutes). If you wish to override this
+ you can set :term:`WATCHDOG_TIMEOUT` to the desired timeout in seconds. Note
+ that the same :term:`WATCHDOG_TIMEOUT` variable also specifies the timeout used
+ for the ``watchdog`` tool (if that is being built).
+- The :ref:`image-buildinfo <ref-classes-image-buildinfo>` class now writes to
+ ``${sysconfdir}/buildinfo`` instead of ``${sysconfdir}/build`` by default (i.e.
+ the default value of :term:`IMAGE_BUILDINFO_FILE` has been changed). If you have
+ code that reads this from images at build or runtime you will need to update it
+ or specify your own value for :term:`IMAGE_BUILDINFO_FILE`.
+- In the :ref:`archiver <ref-classes-archiver>` class, the default
+ ``ARCHIVER_OUTDIR`` value no longer includes the :term:`MACHINE` value in order
+ to avoid the archive task running multiple times in a multiconfig setup. If you
+ have custom code that does something with the files archived by the
+ :ref:`archiver <ref-classes-archiver>` class then you may need to adjust it to
+ the new structure.
+- If you are not using `systemd` then udev is now configured to use labels
+ (``LABEL`` or ``PARTLABEL``) to set the mount point for the device. For example::
+
+ /run/media/rootfs-sda2
+
+ instead of::
+
+ /run/media/sda2
+
+- ``icu`` no longer provides the ``icu-config`` configuration tool - upstream
+ have indicated ``icu-config`` is deprecated and should no longer be used. Code
+ with references to it will need to be updated, for example to use ``pkg-config``
+ instead.
+- The ``rng-tools`` systemd service name has changed from ``rngd`` to ``rng-tools``
+- The ``largefile`` :term:`DISTRO_FEATURES` item has been removed, large file
+ support is now always enabled where it was previously optional.
+- The Python ``zoneinfo`` module is now split out to its own ``python3-zoneinfo``
+ package.
+- The :term:`PACKAGECONFIG` option to enable wpa_supplicant in the ``connman``
+ recipe has been renamed to "wpa-supplicant". If you have set PACKAGECONFIG for
+ the ``connman`` recipe to include this option you will need to update
+ your configuration. Related to this, the :term:`WIRELESS_DAEMON` variable
+ now expects the new ``wpa-supplicant`` naming and affects ``packagegroup-base``
+ as well as ``connman``.
+- The ``wpa-supplicant`` recipe no longer uses a static (and stale) ``defconfig``
+ file, instead it uses the upstream version with appropriate edits for the
+ :term:`PACKAGECONFIG`. If you are customising this file you will need to
+ update your customisations.
+- With the introduction of picobuild in
+ :ref:`python_pep517 <ref-classes-python_pep517>`, The ``PEP517_BUILD_API``
+ variable is no longer supported. If you have any references to this variable
+ you should remove them.
+
+
+.. _migration-4.1-removed-recipes:
+
+Removed recipes
+~~~~~~~~~~~~~~~
+
+The following recipes have been removed in this release:
+
+- ``alsa-utils-scripts``: merged into alsa-utils
+- ``cargo-cross-canadian``: optimised out

+- ``linux-yocto (5.10)``: 5.15 and 5.19 are currently provided
+- ``rust-cross``: optimised out
