Enabling auto-updates will upgrade your WordPress automatically as soon as new minor updates becomes available. This is useful, for example, if you don't perform manual updates regularly and want to make sure you benefit from the latest security and bug fixes.
WordPress classifies its versions with a 3-digit sequence. Minor update releases affect the last number in the sequence (e.g. 5.2.2 to 5.2.3.). A minor release is intended to fix bugs and provide enhancements which will usually not negatively affect your site.
