How to Check & Upgrade to the Latest WordPress Version

WordPress is a well-known Content Management System (CMS) that powers millions of websites worldwide.

It’s essential to keep your WordPress site updated to the latest version, as it can improve your website’s security, performance, and functionality.

In this guide, we’ll guide you how to check your current WordPress version and upgrade to the latest version.

Before we get into the updates, we need to understand why there are so many updates.

Why Does WordPress Release Frequent Updates?

Why WordPress is one of the most popular Content Management Systems (CMS) in the world is because it powers over 44% of all websites on the internet. WordPress is open-source software, which means it’s constantly evolving and improving through contributions from a global community of developers.

WordPress releases frequent updates to address security vulnerabilities, improve performance, add new features, and fix bugs. Here are some reasons why WordPress releases regular updates:


WordPress puts a premium on safety. Because of its widespread adoption, hackers frequently aim their attention at WordPress software.

In order to prevent hackers from exploiting security holes and gaining unauthorized access to your site, data, or code, WordPress releases frequent security patches.

Maintaining an up-to-date WordPress installation is crucial to ensuring the safety of your visitors’ personal information.


Keeping your WordPress installation up-to-date is another great way to boost your site’s speed.

Quicker load times, more efficient coding, and more careful attention to resource allocation are all examples of ways in which things could be made better.

Improvements in usability and search engine rankings are both possible as a result of these alterations.

Updated Functions

Each new version of WordPress includes a slew of improvements and enhancements.

The ability to edit content more efficiently, updated design elements, and more plugins and themes are all examples of what can be added.

By implementing these changes, your website will become more functional, and your users’ experiences will improve.


WordPress updates can also ensure that your website is compatible with the latest web technologies, such as new browsers, mobile devices, and operating systems.

This ensures your website functions properly on all devices and provides the best user experience possible.
