+Porting Guide for v3.4.0
+========================
+
+Known Issues
+------------
+
+dellemc.openmanage
+~~~~~~~~~~~~~~~~~~
+
+- idrac_user - Issue(192043) Module may error out with the message ``unable to perform the import or export operation because there are pending attribute changes or a configuration job is in progress``. Wait for the job to complete and run the task again.
+- ome_configuration_compliance_info - Issue(195592) Module may error out with the message ``unable to process the request because an error occurred``. If the issue persists, report it to the system administrator.
+- ome_smart_fabric - Issue(185322) Only three design types are supported by OpenManage Enterprise Modular but the module successfully creates a fabric when the design type is not supported.
+- ome_smart_fabric_uplink - Issue(186024) ome_smart_fabric_uplink module does not allow the creation of multiple uplinks of the same name even though this is supported by OpenManage Enterprise Modular. If an uplink is created using the same name as an existing uplink, the existing uplink is modified.
+
+Major Changes
+-------------
+
+Ansible-base
+~~~~~~~~~~~~
+
+- ansible-test - Tests run with the ``centos6`` and ``default`` test containers now use a PyPI proxy container to access PyPI when Python 2.6 is used. This allows tests running under Python 2.6 to continue functioning even though PyPI is discontinuing support for non-SNI capable clients.
+
+community.postgresql
+~~~~~~~~~~~~~~~~~~~~
+
+- postgresql_query - the default value of the ``as_single_query`` option will be changed to ``yes`` in community.postgresql 2.0.0 (https://github.com/ansible-collections/community.postgresql/issues/85).
+
+netapp.ontap
+~~~~~~~~~~~~
+
+- na_ontap_autosupport - Added REST support to the module.
+
+Deprecated Features
+-------------------
+
+community.aws
+~~~~~~~~~~~~~
+
+- ec2_vpc_endpoint_info - the ``query`` option has been deprecated and will be removed after 2022-12-01 (https://github.com/ansible-collections/community.aws/pull/346). The ec2_vpc_endpoint_info now defaults to listing information about endpoints. The ability to search for information about available services has been moved to the dedicated module ``ec2_vpc_endpoint_service_info``.
+
+community.docker
+~~~~~~~~~~~~~~~~
+
+- docker_* modules and plugins, except ``docker_swarm`` connection plugin and ``docker_compose`` and ``docker_stack*` modules - the current default ``localhost`` for ``tls_hostname`` is deprecated. In community.docker 2.0.0 it will be computed from ``docker_host`` instead (https://github.com/ansible-collections/community.docker/pull/134).
