Minor update refers to a software update that is usually done to fix bugs, enhance performance or add new features. Because it's just a minor update, it doesn't take a lot of effort and doesn't require any major overhaul of the software. Other synonyms for minor update include "maintenance release," "patch," "hotfix," "bug fix," and "point release." These updates are usually released alongside major updates which contain significant changes. It's important to keep your software up-to-date, even if it's just a minor update, to ensure that it runs at its best performance and is fully secured.
