You will often see a notification with a number of updates available in the WordPress menu. If you are using Smart Inbound Hosting and Support, do not worry about these updates.
If you are not using Smart Inbound paid ongoing support, update at your own risk.
Smart Inbound Hosting makes daily backups of your website: if something breaks due to a plugin or theme update, it is often easiest to load a backup. This means you should make plugin updates before any other large changes for the day.
