WordPress Updates

WordPress updates are new versions of the WordPress software, themes, or plugins that fix bugs, patch security vulnerabilities, and add new features. Each update contains code changes made by developers to make the site more secure, faster, or more user-friendly. For Dutch small and medium-sized businesses, these updates form the foundation of a healthy, secure website that remains protected against hackers and is compatible with modern browsers.

How WordPress Updates Work in Practice

WordPress distinguishes between three types of updates: core updates for the core software, theme updates for the visual design, and plugin updates for additional functionality. Core updates are released on average three to four times a year and include security patches, performance improvements, and sometimes new features such as the block editor. Themes and plugins are released by their own developers, often in response to security vulnerabilities or incompatibility with newer WordPress versions. In the WordPress dashboard, you’ll see a notification as soon as an update is available. You can install it manually or enable automatic updates for minor versions. Major version updates, such as from 6.3 to 6.4, usually need to be initiated manually, as they can sometimes have unexpected consequences for custom code or older themes.

Why WordPress Updates Are Essential for SMB Websites

WordPress is the most widely used website software worldwide, which means hackers actively seek it out to exploit vulnerabilities. A well-known example is the backdoor in certain versions of the Yoast SEO plugin in 2015, which allowed attackers to gain access to thousands of sites. Without updates, you’ll continue to run on code with known vulnerabilities. Additionally, updates improve speed, accessibility, and compatibility with new web standards such as those from the W3C. For small and medium-sized businesses, the benefits are immediately noticeable: a faster site ranks higher in Google, a secure site prevents data breaches that must be reported under the GDPR, and a compatible site works flawlessly on all devices.

What WordPress Updates Mean for Your Business

By updating regularly, you keep your site protected against malware, phishing, and ransomware. In practice, we see with SMB clients that hacked sites are offline for an average of two to five days while being restored, resulting in lost revenue and reputational damage. Updates prevent this. Additionally, you benefit from speed improvements that reduce load times and increase conversion rates. A well-maintained WordPress website is also easier to manage: new features work without custom code, and you’re less likely to encounter conflicts between plugins. Don’t want to check for updates yourself every week? Then a professional WordPress website maintenance subscription will help you implement updates safely and on time, including backups and a testing environment.

You can apply WordPress updates in various situations: from preventive maintenance to resolving urgent security issues. Each type of update has its own purpose and timing. Below, you’ll see which update strategy is right for your business and website.

Security patches for vulnerable plugins and themes

Security updates are often released within 24 hours after a vulnerability is made public. For example, in 2023, a critical vulnerability was discovered in WooCommerce Payments, allowing attackers to intercept payment data. A patch was available within a day. For ecommerce stores and sites handling customer data, applying such updates within 48 hours is crucial. In practice, many small and medium-sized businesses put off updates because they’re afraid something will break. That risk is real, but much smaller than the risk of a hack. Test the update first in a staging environment, check the site, and then deploy it to production. That way, you combine security with stability.

Feature updates for new functionality and user-friendliness

Major WordPress releases sometimes introduce new features that improve your workflow. For example, the introduction of the block editor in version 5.0 made it possible to build landing pages without a page builder. For content marketers, this meant greater control without relying on a developer. Plan feature updates strategically: not immediately upon release, but after a month once any teething issues have been resolved. Check whether your theme and key plugins are compatible. For sites that rely on custom code or older themes, it’s wise to test first. Want to take advantage of new features without any hassle? Then choose a modern, well-maintained theme and limit the number of plugins to only what’s truly necessary.

Compatibility patches for PHP versions and server environments

WordPress runs on PHP, the server-side programming language. Hosting providers regularly update their PHP version for security reasons. Older WordPress versions sometimes no longer work on newer PHP versions, resulting in white screens or error messages. For example, PHP 8.0 introduced stricter rules for data types, causing certain plugins to crash. WordPress core updates ensure your site remains compatible. Check your managed WordPress hosting environment to see which PHP version you’re running. Ideally, you should be on PHP 8.1 or higher. First, update WordPress and your plugins, test everything, and then switch to the newer PHP version. This will help you avoid downtime and performance issues.

When WordPress updates are the right choice—and when they aren’t

Updates are always advisable for security patches and minor version updates. They are less urgent for feature updates if your site is running stably and you don’t need new functionality. Only skip updates if you have an outdated site with custom code that is no longer maintained. In that case, updating is risky without thorough testing and possible code modifications. A complete website redesign is often a better investment than endlessly applying quick fixes. For active sites with customer traffic or ecommerce, updating is always the right choice, provided you do so in a controlled manner using backups and a test environment.
