+Porting Guide for v6.6.0
+========================
+
+Added Collections
+-----------------
+
+- lowlydba.sqlserver (version 1.0.4)
+
+Known Issues
+------------
+
+community.routeros
+~~~~~~~~~~~~~~~~~~
+
+- The ``community.routeros.command`` module claims to support check mode. Since it cannot judge whether the commands executed modify state or not, this behavior is incorrect. Since this potentially breaks existing playbooks, we will not change this behavior until community.routeros 3.0.0.
+
+Breaking Changes
+----------------
+
+community.general
+~~~~~~~~~~~~~~~~~
+
+- newrelic_deployment - ``revision`` is required for v2 API (https://github.com/ansible-collections/community.general/pull/5341).
+
+Major Changes
+-------------
+
+community.general
+~~~~~~~~~~~~~~~~~
+
+- newrelic_deployment - removed New Relic v1 API, added support for v2 API (https://github.com/ansible-collections/community.general/pull/5341).
+
+Deprecated Features
+-------------------
+
+- The mellanox.onyx collection is considered unmaintained and will be removed from Ansible 8 if no one starts maintaining it again before Ansible 8. See `the removal process for details on how this works <https://github.com/ansible-collections/overview/blob/main/removal_from_ansible.rst#cancelling-removal-of-an-unmaintained-collection>`__ (https://github.com/ansible-community/community-topics/issues/136).
+
+cisco.mso
+~~~~~~~~~
+
+- The mso_schema_template_contract_filter contract_filter_type attribute is deprecated. The value is now deduced from filter_type.
+
+community.general
+~~~~~~~~~~~~~~~~~
+
+- ArgFormat module utils - deprecated along ``CmdMixin``, in favor of the ``cmd_runner_fmt`` module util (https://github.com/ansible-collections/community.general/pull/5370).
+- CmdMixin module utils - deprecated in favor of the ``CmdRunner`` module util (https://github.com/ansible-collections/community.general/pull/5370).
+- CmdModuleHelper module utils - deprecated in favor of the ``CmdRunner`` module util (https://github.com/ansible-collections/community.general/pull/5370).
+- CmdStateModuleHelper module utils - deprecated in favor of the ``CmdRunner`` module util (https://github.com/ansible-collections/community.general/pull/5370).
+- django_manage - support for Django releases older than 4.1 has been deprecated and will be removed in community.general 9.0.0 (https://github.com/ansible-collections/community.general/pull/5400).
+- django_manage - support for the commands ``cleanup``, ``syncdb`` and ``validate`` that have been deprecated in Django long time ago will be removed in community.general 9.0.0 (https://github.com/ansible-collections/community.general/pull/5400).
+- django_manage - the behavior of "creating the virtual environment when missing" is being deprecated and will be removed in community.general version 9.0.0 (https://github.com/ansible-collections/community.general/pull/5405).
+- newrelic_deployment - ``appname`` and ``environment`` are no longer valid options in the v2 API. They will be removed in community.general 7.0.0 (https://github.com/ansible-collections/community.general/pull/5341).
