Every time WordPress update comes out, I receive emails from clients asking whether it’s safe to update their WordPress site. They usually want to know the pros and cons of updating WordPress. This article will explain how to properly update WordPress.

With each new update, WordPress fix bugs, add new features, improve performance, and enhance existing features. When you do not update your WordPress site, your website security and improvements are at risk.

1. Security

Security is the most important reason why WordPress site need to be updated. Currently, WordPress powers 23% of all websites in the world. Due to the popularity, WordPress is a popular target for hackers, malicious code distributors, data thieves, and hackers.

This means that if you are not using the latest version of WordPress, then you are using software with known security vulnerabilities. Hackers can search for websites running the older version, and you may become a victim of a sophisticated attack.

2. Cool New Features

Each major WordPress release comes with new features and changes to the software. For example, WordPress 4.0 came with improved plugin install experience, 4.1 introduced inline image editing, and 4.2 came with faster plugin updates.

Now if you were using an older version of WordPress, then your WordPress experience would be a lot different than someone using the latest version.
You will have trouble finding WordPress help online because you are using an older version. Users on WordPress support forums will assume that you are using the latest version of WordPress.

3. Speed

WordPress developers are always trying to make things faster. Each new release comes with several performance improvements that make WordPress run faster and more efficient.
For example, WordPress 4.2 improved JS performance for navigation menus and WordPress 4.1 improved complex queries which helped with the performance of sites using those queries.
Since speed is a huge factor in SEO, you should definitely keep your WordPress updated to ensure maximum performance benefits.

4. Bug Fixes

Despite the rigorous testing of major WordPress releases, sometimes bugs may slip through the cracks. That’s why there are timely minor WordPress releases (the ones with X.X.X) to account for that. For example, the most recent WordPress 4.2.3 update fixed 20 bugs from the 4.2 release.

Now if you go to WordPress support forums asking for help, the first advice you will get is to update WordPress because that may fix the issue. If you insist on not updating WordPress, then you will be unable to receive help.

5. Compatibility (or NOT)

Often plugin and theme developers coordinate their updates with major WordPress releases to ensure they’re taking advantage of newly available features and enhancements.

However, in some cases, an update can break your existing WordPress plugins if they weren’t following the best practices and coding standards.


This is why it is crucial that you keep regular WordPress backups.

To sum this up, the only downside is that in some rare cases your site will break. However, the upside is that you have:

Improved WordPress security
Cool new WordPress features
Faster WordPress experience
A bug-free WordPress website
Better compatibility
Now that you know why it’s important to keep your WordPress site updated, let’s take a look at how to update WordPress.
