WordPress 5.6.2 contains 5 bug fixes that affect WordPress 5.6.1.

If you have WordPress 5.6.1, it is recommended to update to the latest version in order to have those bug fixes in place. These are mostly minor fixes but if you use the Classic Editor – one of these bug fixes addresses the “Leave site” browser alert we have seen since WordPress 5.6.1.
