+Moving to the Yocto Project 2.4 Release
+=======================================
+
+This section provides migration information for moving to the Yocto
+Project 2.4 Release from the prior release.
+
+.. _migration-2.4-memory-resident-mode:
+
+Memory Resident Mode
+--------------------
+
+A persistent mode is now available in BitBake's default operation,
+replacing its previous "memory resident mode" (i.e.
+``oe-init-build-env-memres``). Now you only need to set
+:term:`BB_SERVER_TIMEOUT` to a timeout (in
+seconds) and BitBake's server stays resident for that amount of time
+between invocations. The ``oe-init-build-env-memres`` script has been
+removed since a separate environment setup script is no longer needed.
+
+.. _migration-2.4-packaging-changes:
+
+Packaging Changes
+-----------------
+
+This section provides information about packaging changes that have
+occurred:
+
+- ``python3`` Changes:
+
+ - The main "python3" package now brings in all of the standard
+ Python 3 distribution rather than a subset. This behavior matches
+ what is expected based on traditional Linux distributions. If you
+ wish to install a subset of Python 3, specify ``python-core`` plus
+ one or more of the individual packages that are still produced.
+
+ - ``python3``: The ``bz2.py``, ``lzma.py``, and
+ ``_compression.py`` scripts have been moved from the
+ ``python3-misc`` package to the ``python3-compression`` package.
+
+- ``binutils``: The ``libbfd`` library is now packaged in a separate
+ "libbfd" package. This packaging saves space when certain tools (e.g.
+ ``perf``) are installed. In such cases, the tools only need
+ ``libbfd`` rather than all the packages in ``binutils``.
+
+- ``util-linux`` Changes:
+
+ - The ``su`` program is now packaged in a separate "util-linux-su"
+ package, which is only built when "pam" is listed in the
+ :term:`DISTRO_FEATURES` variable.
+ ``util-linux`` should not be installed unless it is needed because
+ ``su`` is normally provided through the shadow file format. The
+ main ``util-linux`` package has runtime dependencies (i.e.
+ :term:`RDEPENDS`) on the ``util-linux-su`` package
+ when "pam" is in ``DISTRO_FEATURES``.
+
+ - The ``switch_root`` program is now packaged in a separate
+ "util-linux-switch-root" package for small initramfs images that
+ do not need the whole ``util-linux`` package or the busybox
+ binary, which are both much larger than ``switch_root``. The main
+ ``util-linux`` package has a recommended runtime dependency (i.e.
+ :term:`RRECOMMENDS`) on the
+ ``util-linux-switch-root`` package.
+
+ - The ``ionice`` program is now packaged in a separate
+ "util-linux-ionice" package. The main ``util-linux`` package has a
+ recommended runtime dependency (i.e. ``RRECOMMENDS``) on the
+ ``util-linux-ionice`` package.
+
+- ``initscripts``: The ``sushell`` program is now packaged in a
+ separate "initscripts-sushell" package. This packaging change allows
+ systems to pull ``sushell`` in when ``selinux`` is enabled. The
+ change also eliminates needing to pull in the entire ``initscripts``
+ package. The main ``initscripts`` package has a runtime dependency
+ (i.e. ``RDEPENDS``) on the ``sushell`` package when "selinux" is in
+ ``DISTRO_FEATURES``.
+
+- ``glib-2.0``: The ``glib-2.0`` package now has a recommended
+ runtime dependency (i.e. ``RRECOMMENDS``) on the ``shared-mime-info``
+ package, since large portions of GIO are not useful without the MIME
+ database. You can remove the dependency by using the
+ :term:`BAD_RECOMMENDATIONS` variable if
+ ``shared-mime-info`` is too large and is not required.
+
+- *Go Standard Runtime:* The Go standard runtime has been split out
+ from the main ``go`` recipe into a separate ``go-runtime`` recipe.
+
+.. _migration-2.4-removed-recipes:
+
+Removed Recipes
+---------------
+
+The following recipes have been removed:
+
+- ``acpitests``: This recipe is not maintained.
+
+- ``autogen-native``: No longer required by Grub, oe-core, or
+ meta-oe.
+
+- ``bdwgc``: Nothing in OpenEmbedded-Core requires this recipe. It
+ has moved to meta-oe.
+
+- ``byacc``: This recipe was only needed by rpm 5.x and has moved to
+ meta-oe.
+
+- ``gcc (5.4)``: The 5.4 series dropped the recipe in favor of 6.3 /
+ 7.2.
+
+- ``gnome-common``: Deprecated upstream and no longer needed.
+
+- ``go-bootstrap-native``: Go 1.9 does its own bootstrapping so this
+ recipe has been removed.
+
+- ``guile``: This recipe was only needed by ``autogen-native`` and
+ ``remake``. The recipe is no longer needed by either of these
+ programs.
+
+- ``libclass-isa-perl``: This recipe was previously needed for LSB 4,
+ no longer needed.
+
+- ``libdumpvalue-perl``: This recipe was previously needed for LSB 4,
+ no longer needed.
+
+- ``libenv-perl``: This recipe was previously needed for LSB 4, no
+ longer needed.
+
+- ``libfile-checktree-perl``: This recipe was previously needed for
+ LSB 4, no longer needed.
+
+- ``libi18n-collate-perl``: This recipe was previously needed for LSB
+ 4, no longer needed.
+
+- ``libiconv``: This recipe was only needed for ``uclibc``, which was
+ removed in the previous release. ``glibc`` and ``musl`` have their
+ own implementations. ``meta-mingw`` still needs ``libiconv``, so it
+ has been moved to ``meta-mingw``.
+
+- ``libpng12``: This recipe was previously needed for LSB. The
+ current ``libpng`` is 1.6.x.
+
+- ``libpod-plainer-perl``: This recipe was previously needed for LSB
+ 4, no longer needed.
+
+- ``linux-yocto (4.1)``: This recipe was removed in favor of 4.4,
+ 4.9, 4.10 and 4.12.
+
+- ``mailx``: This recipe was previously only needed for LSB
+ compatibility, and upstream is defunct.
+
+- ``mesa (git version only)``: The git version recipe was stale with
+ respect to the release version.
+
+- ``ofono (git version only)``: The git version recipe was stale with
+ respect to the release version.
+
+- ``portmap``: This recipe is obsolete and is superseded by
+ ``rpcbind``.
+
+- ``python3-pygpgme``: This recipe is old and unmaintained. It was
+ previously required by ``dnf``, which has switched to official
+ ``gpgme`` Python bindings.
+
+- ``python-async``: This recipe has been removed in favor of the
+ Python 3 version.
+
+- ``python-gitdb``: This recipe has been removed in favor of the
+ Python 3 version.
+
+- ``python-git``: This recipe was removed in favor of the Python 3
+ version.
+
+- ``python-mako``: This recipe was removed in favor of the Python 3
+ version.
+
+- ``python-pexpect``: This recipe was removed in favor of the Python
+ 3 version.
+
+- ``python-ptyprocess``: This recipe was removed in favor of Python
+ the 3 version.
+
+- ``python-pycurl``: Nothing is using this recipe in
+ OpenEmbedded-Core (i.e. ``meta-oe``).
+
+- ``python-six``: This recipe was removed in favor of the Python 3
+ version.
+
+- ``python-smmap``: This recipe was removed in favor of the Python 3
+ version.
+
+- ``remake``: Using ``remake`` as the provider of ``virtual/make`` is
+ broken. Consequently, this recipe is not needed in OpenEmbedded-Core.
+
+.. _migration-2.4-kernel-device-tree-move:
+
+Kernel Device Tree Move
+-----------------------
+
+Kernel Device Tree support is now easier to enable in a kernel recipe.
+The Device Tree code has moved to a
+:ref:`kernel-devicetree <ref-classes-kernel-devicetree>` class.
+Functionality is automatically enabled for any recipe that inherits the
+:ref:`kernel <ref-classes-kernel>` class and sets the
+:term:`KERNEL_DEVICETREE` variable. The
+previous mechanism for doing this,
+``meta/recipes-kernel/linux/linux-dtb.inc``, is still available to avoid
+breakage, but triggers a deprecation warning. Future releases of the
+Yocto Project will remove ``meta/recipes-kernel/linux/linux-dtb.inc``.
+It is advisable to remove any ``require`` statements that request
+``meta/recipes-kernel/linux/linux-dtb.inc`` from any custom kernel
+recipes you might have. This will avoid breakage in post 2.4 releases.
+
+.. _migration-2.4-package-qa-changes:
+
+Package QA Changes
+------------------
+
+The following package QA changes took place:
+
+- The "unsafe-references-in-scripts" QA check has been removed.
+
+- If you refer to ``${COREBASE}/LICENSE`` within
+ :term:`LIC_FILES_CHKSUM` you receive a
+ warning because this file is a description of the license for
+ OE-Core. Use ``${COMMON_LICENSE_DIR}/MIT`` if your recipe is
+ MIT-licensed and you cannot use the preferred method of referring to
+ a file within the source tree.
+
+.. _migration-2.4-readme-changes:
+
+``README`` File Changes
+-----------------------
+
+The following are changes to ``README`` files:
+
+- The main Poky ``README`` file has been moved to the ``meta-poky``
+ layer and has been renamed ``README.poky``. A symlink has been
+ created so that references to the old location work.
+
+- The ``README.hardware`` file has been moved to ``meta-yocto-bsp``. A
+ symlink has been created so that references to the old location work.
+
+- A ``README.qemu`` file has been created with coverage of the
+ ``qemu*`` machines.
+
+.. _migration-2.4-miscellaneous-changes:
+
+Miscellaneous Changes
+---------------------
+
+The following are additional changes:
+
+- The ``ROOTFS_PKGMANAGE_BOOTSTRAP`` variable and any references to it
+ have been removed. You should remove this variable from any custom
+ recipes.
+
+- The ``meta-yocto`` directory has been removed.
+
+ .. note::
+
+ In the Yocto Project 2.1 release
+ meta-yocto
+ was renamed to
+ meta-poky
+ and the
+ meta-yocto
+ subdirectory remained to avoid breaking existing configurations.
+
+- The ``maintainers.inc`` file, which tracks maintainers by listing a
+ primary person responsible for each recipe in OE-Core, has been moved
+ from ``meta-poky`` to OE-Core (i.e. from
+ ``meta-poky/conf/distro/include`` to ``meta/conf/distro/include``).
+
+- The :ref:`buildhistory <ref-classes-buildhistory>` class now makes
+ a single commit per build rather than one commit per subdirectory in
+ the repository. This behavior assumes the commits are enabled with
+ :term:`BUILDHISTORY_COMMIT` = "1", which
+ is typical. Previously, the ``buildhistory`` class made one commit
+ per subdirectory in the repository in order to make it easier to see
+ the changes for a particular subdirectory. To view a particular
+ change, specify that subdirectory as the last parameter on the
+ ``git show`` or ``git diff`` commands.
+
+- The ``x86-base.inc`` file, which is included by all x86-based machine
+ configurations, now sets :term:`IMAGE_FSTYPES`
+ using ``?=`` to "live" rather than appending with ``+=``. This change
+ makes the default easier to override.
+
+- BitBake fires multiple "BuildStarted" events when multiconfig is
+ enabled (one per configuration). For more information, see the
+ ":ref:`Events <bitbake:bitbake-user-manual/bitbake-user-manual-metadata:events>`" section in the BitBake User
+ Manual.
+
+- By default, the ``security_flags.inc`` file sets a
+ :term:`GCCPIE` variable with an option to enable
+ Position Independent Executables (PIE) within ``gcc``. Enabling PIE
+ in the GNU C Compiler (GCC), makes Return Oriented Programming (ROP)
+ attacks much more difficult to execute.
+
+- OE-Core now provides a ``bitbake-layers`` plugin that implements a
+ "create-layer" subcommand. The implementation of this subcommand has
+ resulted in the ``yocto-layer`` script being deprecated and will
+ likely be removed in the next Yocto Project release.
+
+- The ``vmdk``, ``vdi``, and ``qcow2`` image file types are now used in
+ conjunction with the "wic" image type through ``CONVERSION_CMD``.
+ Consequently, the equivalent image types are now ``wic.vmdk``,
+ ``wic.vdi``, and ``wic.qcow2``, respectively.
+
+- ``do_image_<type>[depends]`` has replaced ``IMAGE_DEPENDS_<type>``.
+ If you have your own classes that implement custom image types, then
+ you need to update them.
+
+- OpenSSL 1.1 has been introduced. However, the default is still 1.0.x
+ through the :term:`PREFERRED_VERSION`
+ variable. This preference is set is due to the remaining
+ compatibility issues with other software. The
+ :term:`PROVIDES` variable in the openssl 1.0 recipe
+ now includes "openssl10" as a marker that can be used in
+ :term:`DEPENDS` within recipes that build software
+ that still depend on OpenSSL 1.0.
+
+- To ensure consistent behavior, BitBake's "-r" and "-R" options (i.e.
+ prefile and postfile), which are used to read or post-read additional
+ configuration files from the command line, now only affect the
+ current BitBake command. Before these BitBake changes, these options
+ would "stick" for future executions.
+
