Go language changes
~~~~~~~~~~~~~~~~~~~
The ``linkmode`` flag was dropped from ``GO_LDFLAGS`` for ``nativesdk`` and
``cross-canadian``. Also, dynamic linking was disabled for the whole set of
(previously) supported architectures in the ``goarch`` class.
.. _migration-5.0-systemd-changes:
systemd changes
~~~~~~~~~~~~~~~
Systemd's nss-resolve plugin is now supported and can be added via the
``nss-resolve`` :term:`PACKAGECONFIG` option , which is from now on required
(along with ``resolved``) by the ``systemd-resolved`` feature. Related to that
(i.e., Systemd's network name resolution), an option to use ``stub-resolv.conf``
was added as well.

QEMU changes
~~~~~~~~~~~~
In ``tune-core2``, the cpu models ``n270`` and ``core2duo`` are no longer
passed to QEMU, since its documentation recommends not using them with ``-cpu``
option. Therefore, from now on, ``Nehalem`` model is used instead.

Miscellaneous changes

- ``bitbake-whatchanged`` script was removed.
- ``ccache`` no longer supports FORTRAN.
