We recommend that you review Installation Messages immediately after updating the Joomla! CMS.
If there are any new messages after you update your website's Joomla! CMS then you will see a yellow box displayed next to Installation Messages in the Information panel of the System Dashboard.
The yellow box will look like the one next to Warnings in the image below.
If you need help implementing changes recommended by an Installation Message, we can help.
