+Release 1.6 (daisy)
+===================
+
+This section provides migration information for moving to the Yocto
+Project 1.6 Release (codename "daisy") from the prior release.
+
+.. _migration-1.6-archiver-class:
+
+``archiver`` Class
+------------------
+
+The :ref:`archiver <ref-classes-archiver>` class has been rewritten
+and its configuration has been simplified. For more details on the
+source archiver, see the
+":ref:`dev-manual/common-tasks:maintaining open source license compliance during your product's lifecycle`"
+section in the Yocto Project Development Tasks Manual.
+
+.. _migration-1.6-packaging-changes:
+
+Packaging Changes
+-----------------
+
+The following packaging changes have been made:
+
+-  The ``binutils`` recipe no longer produces a ``binutils-symlinks``
+   package. ``update-alternatives`` is now used to handle the preferred
+   ``binutils`` variant on the target instead.
+
+-  The tc (traffic control) utilities have been split out of the main
+   ``iproute2`` package and put into the ``iproute2-tc`` package.
+
+-  The ``gtk-engines`` schemas have been moved to a dedicated
+   ``gtk-engines-schemas`` package.
+
+-  The ``armv7a`` with thumb package architecture suffix has changed.
+   The suffix for these packages with the thumb optimization enabled is
+   "t2" as it should be. Use of this suffix was not the case in the 1.5
+   release. Architecture names will change within package feeds as a
+   result.
+
+.. _migration-1.6-bitbake:
+
+BitBake
+-------
+
+The following changes have been made to :term:`BitBake`.
+
+.. _migration-1.6-matching-branch-requirement-for-git-fetching:
+
+Matching Branch Requirement for Git Fetching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When fetching source from a Git repository using
+:term:`SRC_URI`, BitBake will now validate the
+:term:`SRCREV` value against the branch. You can specify
+the branch using the following form::
+
+      SRC_URI = "git://server.name/repository;branch=branchname"
+
+If you do not specify a branch, BitBake looks in the default "master" branch.
+
+Alternatively, if you need to bypass this check (e.g. if you are
+fetching a revision corresponding to a tag that is not on any branch),
+you can add ";nobranch=1" to the end of the URL within :term:`SRC_URI`.
+
+.. _migration-1.6-bitbake-deps:
+
+Python Definition substitutions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+BitBake had some previously deprecated Python definitions within its
+``bb`` module removed. You should use their sub-module counterparts
+instead:
+
+-  ``bb.MalformedUrl``: Use ``bb.fetch.MalformedUrl``.
+
+-  ``bb.encodeurl``: Use ``bb.fetch.encodeurl``.
+
+-  ``bb.decodeurl``: Use ``bb.fetch.decodeurl``
+
+-  ``bb.mkdirhier``: Use ``bb.utils.mkdirhier``.
+
+-  ``bb.movefile``: Use ``bb.utils.movefile``.
+
+-  ``bb.copyfile``: Use ``bb.utils.copyfile``.
+
+-  ``bb.which``: Use ``bb.utils.which``.
+
+-  ``bb.vercmp_string``: Use ``bb.utils.vercmp_string``.
+
+-  ``bb.vercmp``: Use ``bb.utils.vercmp``.
+
+.. _migration-1.6-bitbake-fetcher:
+
+SVK Fetcher
+~~~~~~~~~~~
+
+The SVK fetcher has been removed from BitBake.
+
+.. _migration-1.6-bitbake-console-output:
+
+Console Output Error Redirection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The BitBake console UI will now output errors to ``stderr`` instead of
+``stdout``. Consequently, if you are piping or redirecting the output of
+``bitbake`` to somewhere else, and you wish to retain the errors, you
+will need to add ``2>&1`` (or something similar) to the end of your
+``bitbake`` command line.
+
+.. _migration-1.6-task-taskname-overrides:
+
+``task-``\ taskname Overrides
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``task-``\ taskname overrides have been adjusted so that tasks whose
+names contain underscores have the underscores replaced by hyphens for
+the override so that they now function properly. For example, the task
+override for :ref:`ref-tasks-populate_sdk` is
+``task-populate-sdk``.
+
+.. _migration-1.6-variable-changes:
+
+Changes to Variables
+--------------------
+
+The following variables have changed. For information on the
+OpenEmbedded build system variables, see the ":doc:`/ref-manual/variables`" Chapter.
+
+.. _migration-1.6-variable-changes-TMPDIR:
+
+``TMPDIR``
+~~~~~~~~~~
+
+:term:`TMPDIR` can no longer be on an NFS mount. NFS does
+not offer full POSIX locking and inode consistency and can cause
+unexpected issues if used to store :term:`TMPDIR`.
+
+The check for this occurs on startup. If :term:`TMPDIR` is detected on an
+NFS mount, an error occurs.
+
+.. _migration-1.6-variable-changes-PRINC:
+
+``PRINC``
+~~~~~~~~~
+
+The ``PRINC`` variable has been deprecated and triggers a warning if
+detected during a build. For :term:`PR` increments on changes,
+use the PR service instead. You can find out more about this service in
+the ":ref:`dev-manual/common-tasks:working with a pr service`"
+section in the Yocto Project Development Tasks Manual.
+
+.. _migration-1.6-variable-changes-IMAGE_TYPES:
+
+``IMAGE_TYPES``
+~~~~~~~~~~~~~~~
+
+The "sum.jffs2" option for :term:`IMAGE_TYPES` has
+been replaced by the "jffs2.sum" option, which fits the processing
+order.
+
+.. _migration-1.6-variable-changes-COPY_LIC_MANIFEST:
+
+``COPY_LIC_MANIFEST``
+~~~~~~~~~~~~~~~~~~~~~
+
+The :term:`COPY_LIC_MANIFEST` variable must now
+be set to "1" rather than any value in order to enable it.
+
+.. _migration-1.6-variable-changes-COPY_LIC_DIRS:
+
+``COPY_LIC_DIRS``
+~~~~~~~~~~~~~~~~~
+
+The :term:`COPY_LIC_DIRS` variable must now be set
+to "1" rather than any value in order to enable it.
+
+.. _migration-1.6-variable-changes-PACKAGE_GROUP:
+
+``PACKAGE_GROUP``
+~~~~~~~~~~~~~~~~~
+
+The ``PACKAGE_GROUP`` variable has been renamed to
+:term:`FEATURE_PACKAGES` to more accurately
+reflect its purpose. You can still use ``PACKAGE_GROUP`` but the
+OpenEmbedded build system produces a warning message when it encounters
+the variable.
+
+.. _migration-1.6-variable-changes-variable-entry-behavior:
+
+Preprocess and Post Process Command Variable Behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following variables now expect a semicolon separated list of
+functions to call and not arbitrary shell commands:
+
+  - :term:`ROOTFS_PREPROCESS_COMMAND`
+  - :term:`ROOTFS_POSTPROCESS_COMMAND`
+  - :term:`SDK_POSTPROCESS_COMMAND`
+  - :term:`POPULATE_SDK_POST_TARGET_COMMAND`
+  - :term:`POPULATE_SDK_POST_HOST_COMMAND`
+  - :term:`IMAGE_POSTPROCESS_COMMAND`
+  - :term:`IMAGE_PREPROCESS_COMMAND`
+  - :term:`ROOTFS_POSTUNINSTALL_COMMAND`
+  - :term:`ROOTFS_POSTINSTALL_COMMAND`
+
+For
+migration purposes, you can simply wrap shell commands in a shell
+function and then call the function. Here is an example::
+
+   my_postprocess_function() {
+      echo "hello" > ${IMAGE_ROOTFS}/hello.txt
+   }
+   ROOTFS_POSTPROCESS_COMMAND += "my_postprocess_function; "
+
+.. _migration-1.6-package-test-ptest:
+
+Package Test (ptest)
+--------------------
+
+Package Tests (ptest) are built but not installed by default. For
+information on using Package Tests, see the
+":ref:`dev-manual/common-tasks:testing packages with ptest`"
+section in the Yocto Project Development Tasks Manual. For information on the
+``ptest`` class, see the ":ref:`ptest.bbclass <ref-classes-ptest>`"
+section.
+
+.. _migration-1.6-build-changes:
+
+Build Changes
+-------------
+
+Separate build and source directories have been enabled by default for
+selected recipes where it is known to work (a whitelist) and for all
+recipes that inherit the :ref:`cmake <ref-classes-cmake>` class. In
+future releases the :ref:`autotools <ref-classes-autotools>` class
+will enable a separate build directory by default as well. Recipes
+building Autotools-based software that fails to build with a separate
+build directory should be changed to inherit from the
+:ref:`autotools-brokensep <ref-classes-autotools>` class instead of
+the ``autotools`` or ``autotools_stage``\ classes.
+
+.. _migration-1.6-building-qemu-native:
+
+``qemu-native``
+---------------
+
+``qemu-native`` now builds without SDL-based graphical output support by
+default. The following additional lines are needed in your
+``local.conf`` to enable it::
+
+   PACKAGECONFIG_pn-qemu-native = "sdl"
+   ASSUME_PROVIDED += "libsdl-native"
+
+.. note::
+
+   The default ``local.conf`` contains these statements. Consequently, if you
+   are building a headless system and using a default ``local.conf``
+   file, you will need comment these two lines out.
+
+.. _migration-1.6-core-image-basic:
+
+``core-image-basic``
+--------------------
+
+``core-image-basic`` has been renamed to ``core-image-full-cmdline``.
+
+In addition to ``core-image-basic`` being renamed,
+``packagegroup-core-basic`` has been renamed to
+``packagegroup-core-full-cmdline`` to match.
+
+.. _migration-1.6-licensing:
+
+Licensing
+---------
+
+The top-level :term:`LICENSE` file has been changed to better describe the
+license of the various components of :term:`OpenEmbedded-Core (OE-Core)`. However,
+the licensing itself remains unchanged.
+
+Normally, this change would not cause any side-effects. However, some
+recipes point to this file within
+:term:`LIC_FILES_CHKSUM` (as
+``${COREBASE}/LICENSE``) and thus the accompanying checksum must be
+changed from 3f40d7994397109285ec7b81fdeb3b58 to
+4d92cd373abda3937c2bc47fbc49d690. A better alternative is to have
+:term:`LIC_FILES_CHKSUM` point to a file describing the license that is
+distributed with the source that the recipe is building, if possible,
+rather than pointing to ``${COREBASE}/LICENSE``.
+
+.. _migration-1.6-cflags-options:
+
+``CFLAGS`` Options
+------------------
+
+The "-fpermissive" option has been removed from the default
+:term:`CFLAGS` value. You need to take action on
+individual recipes that fail when building with this option. You need to
+either patch the recipes to fix the issues reported by the compiler, or
+you need to add "-fpermissive" to :term:`CFLAGS` in the recipes.
+
+.. _migration-1.6-custom-images:
+
+Custom Image Output Types
+-------------------------
+
+Custom image output types, as selected using
+:term:`IMAGE_FSTYPES`, must declare their
+dependencies on other image types (if any) using a new
+:term:`IMAGE_TYPEDEP` variable.
+
+.. _migration-1.6-do-package-write-task:
+
+Tasks
+-----
+
+The ``do_package_write`` task has been removed. The task is no longer
+needed.
+
+.. _migration-1.6-update-alternatives-provider:
+
+``update-alternative`` Provider
+-------------------------------
+
+The default ``update-alternatives`` provider has been changed from
+``opkg`` to ``opkg-utils``. This change resolves some troublesome
+circular dependencies. The runtime package has also been renamed from
+``update-alternatives-cworth`` to ``update-alternatives-opkg``.
+
+.. _migration-1.6-virtclass-overrides:
+
+``virtclass`` Overrides
+-----------------------
+
+The ``virtclass`` overrides are now deprecated. Use the equivalent class
+overrides instead (e.g. ``virtclass-native`` becomes ``class-native``.)
+
+.. _migration-1.6-removed-renamed-recipes:
+
+Removed and Renamed Recipes
+---------------------------
+
+The following recipes have been removed:
+
+-  ``packagegroup-toolset-native`` - This recipe is largely unused.
+
+-  ``linux-yocto-3.8`` - Support for the Linux yocto 3.8 kernel has been
+   dropped. Support for the 3.10 and 3.14 kernels have been added with
+   the ``linux-yocto-3.10`` and ``linux-yocto-3.14`` recipes.
+
+-  ``ocf-linux`` - This recipe has been functionally replaced using
+   ``cryptodev-linux``.
+
+-  ``genext2fs`` - ``genext2fs`` is no longer used by the build system
+   and is unmaintained upstream.
+
+-  ``js`` - This provided an ancient version of Mozilla's javascript
+   engine that is no longer needed.
+
+-  ``zaurusd`` - The recipe has been moved to the ``meta-handheld``
+   layer.
+
+-  ``eglibc 2.17`` - Replaced by the ``eglibc 2.19`` recipe.
+
+-  ``gcc 4.7.2`` - Replaced by the now stable ``gcc 4.8.2``.
+
+-  ``external-sourcery-toolchain`` - this recipe is now maintained in
+   the ``meta-sourcery`` layer.
+
+-  ``linux-libc-headers-yocto 3.4+git`` - Now using version 3.10 of the
+   ``linux-libc-headers`` by default.
+
+-  ``meta-toolchain-gmae`` - This recipe is obsolete.
+
+-  ``packagegroup-core-sdk-gmae`` - This recipe is obsolete.
+
+-  ``packagegroup-core-standalone-gmae-sdk-target`` - This recipe is
+   obsolete.
+
+.. _migration-1.6-removed-classes:
+
+Removed Classes
+---------------
+
+The following classes have become obsolete and have been removed:
+
+-  ``module_strip``
+
+-  ``pkg_metainfo``
+
+-  ``pkg_distribute``
+
+-  ``image-empty``
+
+.. _migration-1.6-reference-bsps:
+
+Reference Board Support Packages (BSPs)
+---------------------------------------
+
+The following reference BSPs changes occurred:
+
+-  The BeagleBoard (``beagleboard``) ARM reference hardware has been
+   replaced by the BeagleBone (``beaglebone``) hardware.
+
+-  The RouterStation Pro (``routerstationpro``) MIPS reference hardware
+   has been replaced by the EdgeRouter Lite (``edgerouter``) hardware.
+
+The previous reference BSPs for the ``beagleboard`` and
+``routerstationpro`` machines are still available in a new
+``meta-yocto-bsp-old`` layer in the
+:yocto_git:`Source Repositories <>` at
+:yocto_git:`/meta-yocto-bsp-old/`.
