54 -  BitBake now supports a ``_remove`` operator. The addition of this
59 -  BitBake's global method pool has been removed. This method is not
63 -  The "none" server backend has been removed. The "process" server
64    backend has been serving well as the default for a long time now.
66 -  The ``bitbake-runtask`` script has been removed.
68 -  ``${``\ :term:`P`\ ``}`` and
69    ``${``\ :term:`PF`\ ``}`` are no longer added to
70    :term:`PROVIDES` by default in ``bitbake.conf``.
71    These version-specific :term:`PROVIDES` items were seldom used.
76 .. _migration-1.5-qa-warnings:
79 -----------
83 -  If you have customized :term:`ERROR_QA` or
84    :term:`WARN_QA` values in your configuration, check
87    item not mentioned in :term:`ERROR_QA` or :term:`WARN_QA` would be treated as
89    the default value of :term:`WARN_QA`. All of the possible QA checks are
90    now documented in the ":ref:`ref-classes-insane`" section.
92 -  An additional QA check has been added to check if
94    this file within :ref:`ref-tasks-install` if "make

100    Thus, if you have customized your :term:`ERROR_QA` or :term:`WARN_QA` values
102    "version-going-backwards" to your value for one or the other
104    documented QA checks in the ":ref:`ref-classes-insane`" section.
106 .. _migration-1.5-directory-layout-changes:
109 ------------------------

117 -  Images and related files are now installed into a directory that is
120    :term:`DEPLOY_DIR_IMAGE` variable continues
122    :term:`MACHINE` and should be used anywhere there is a
126    :term:`DEPLOY_DIR_IMAGE` variable in the external environment.
128 -  When buildhistory is enabled, its output is now written under the
129    :term:`Build Directory` rather than
130    :term:`TMPDIR`. Doing so makes it easier to delete
131    :term:`TMPDIR` and preserve the build history. Additionally, data for
132    produced SDKs is now split by :term:`IMAGE_NAME`.
134 -  The ``pkgdata`` directory produced as part of the packaging process
135    has been collapsed into a single machine-specific directory. This
136    directory is located under ``sysroots`` and uses a machine-specific

159 -  The value of :term:`IMAGE_FEATURES` is now validated to ensure invalid
162    :term:`IMAGE_INSTALL` in order to have the
164    intended to catch those kinds of situations. Valid :term:`IMAGE_FEATURES`
166    :term:`COMPLEMENTARY_GLOB` and a new
167    "validitems" varflag on :term:`IMAGE_FEATURES`. The "validitems" varflag
171 -  The previously deprecated "apps-console-core" :term:`IMAGE_FEATURES` item
172    is no longer supported. Add "splash" to :term:`IMAGE_FEATURES` if you
174    apps-console-core was doing.

191 --------------------------------------------------------
193 The image ``core-image-minimal`` no longer adds
195 :term:`ROOTFS_POSTPROCESS_COMMAND`.
196 This addition is now handled automatically when "package-management" is
197 not in :term:`IMAGE_FEATURES`. If you have custom

250 .. _migration-1.5-build-history:
253 -------------
257 -  Installed package sizes: ``installed-package-sizes.txt`` for an image
261 -  The dependency graphs (``depends*.dot``) now use the actual package
265 -  The ``buildhistory-diff`` and ``buildhistory-collect-srcrevs``
266    utilities have improved command-line handling. Use the ``--help``

276 --------
280 -  ``udev`` no longer brings in ``udev-extraconf`` automatically through

285 -  ``udev`` no longer brings in ``pciutils-ids`` or ``usbutils-ids``
286    through :term:`RRECOMMENDS`. These are not needed by ``udev`` itself and
