+Porting Guide for v10.4.0
+=========================

+Known Issues
+------------
+
+dellemc.openmanage
+~~~~~~~~~~~~~~~~~~
+
+- idrac_diagnostics - Issue(285322) - This module doesn't support export of diagnostics file to HTTP and HTTPS share via SOCKS proxy.
+- idrac_firmware - Issue(279282) - This module does not support firmware update using HTTP, HTTPS, and FTP shares with authentication on iDRAC8.
+- idrac_storage_volume - Issue(290766) - The module will report success instead of showing failure for new virtual creation on the BOSS-N1 controller if a virtual disk is already present on the same controller.
+- idrac_support_assist - Issue(308550) - This module fails when the NFS share path contains sub directory.
+- ome_diagnostics - Issue(279193) - Export of SupportAssist collection logs to the share location fails on OME version 4.0.0.
+- ome_smart_fabric_uplink - Issue(186024) - The module supported by OpenManage Enterprise Modular, however it does not allow the creation of multiple uplinks of the same name. If an uplink is created using the same name as an existing uplink, then the existing uplink is modified.
+
+Breaking Changes
+----------------
+
+community.mysql
+~~~~~~~~~~~~~~~
+
+- collection - support of mysqlclient connector is deprecated - use PyMySQL connector instead! We will stop testing against it in collection version 4.0.0 and remove the related code in 5.0.0 (https://github.com/ansible-collections/community.mysql/issues/654).
+- mysql_info - The ``users_info`` filter returned variable ``plugin_auth_string`` contains the hashed password and it's misleading, it will be removed from community.mysql 4.0.0. Use the `plugin_hash_string` return value instead (https://github.com/ansible-collections/community.mysql/pull/629).
+- mysql_user - the ``user`` alias of the ``name`` argument has been deprecated and will be removed in collection version 5.0.0. Use the ``name`` argument instead.
