Have you ever questioned the necessity and timing of performing WordPress website software updates? Depending on who you talk to, you’ll get answers with a wide range of severity. Some are staunch supporters of regular software updates; others say to let it go until something breaks. The reality is somewhere in the middle, and the best answers are different for everyone.
WordPress website software updates are only one slice of the pie that makes up your whole website maintenance strategy, but they are a very significant piece. They are a must-do website maintenance task. How often you do them will depend on your website stack and your tolerance for risk.
In this article, we’ll discuss what’s happening behind the scenes with the updates and how keeping a frequent update schedule benefits you for reasons other than security. You will see more articles soon about the other components of a regular website maintenance practice, but for now, we’re looking to understand why it even matters.
Why Software Updates Happen
WordPress is open source, meaning its code is available for anyone to use, modify, and improve. The current community of contributors is global. Anyone, anywhere, can create a plugin, theme, or code patch and make it available.
This distributed network of creators means everyone is working at their own pace and timeline. As a result, hundreds of thousands of individual WordPress tools/plugins/themes are updated asynchronously.
So, if you have ever questioned how often you should update your website software, this is something important to consider. The development, patch, and feature improvement cadence is different for each software. Something complex and feature-rich, like WooCommerce, will get updates more often than a simple singular tool, like a tree view for your page admin screen.
When deciding on a software update maintenance schedule, consider how actively you publish and how actively the tools you use are updated. The frequency of software updates should reflect the complexity and activity level of your website management and administrative work.
What Software Updates Contain
When you see an update notification, it could be addressing more than one thing:
- Bug Fixes: Correcting errors or glitches.
- Performance Enhancements: Tweaks that make your site run more efficiently.
- Security Patches: Closing vulnerabilities that could expose your site to risks.
Updates are less about solving immediate problems and more about maintaining your site’s health and compatibility over time.
Software Updates And Compatability
Think of your WordPress website as a team working toward the same goal. The WordPress core is the coach, plugins are the players, and themes set the stage. When one part of the team changes—say, a plugin gets an update—everyone else needs to adapt to stay in sync. Skipping updates can leave parts of your “team” out of step, potentially leading to:
- Features not working as intended.
- Pages displaying incorrectly.
- Site-wide problems and conflicts.
By keeping everything updated, you ensure your site operates smoothly and minimizes the risk of code conflicts.
Software Update Changelogs
Each update comes with a changelog, which is essentially a summary of what’s new. Here’s why it matters:
- New Features: Helps you understand enhancements.
- Fixes: Shows resolved bugs that could impact performance.
- Security Patches: Highlights vulnerabilities that updates address.
When reading a changelog, look for key terms like “security fix,” “compatibility update,” or “deprecated functionality.” These terms can help you prioritize whether an update needs immediate attention or can wait until your next scheduled maintenance session.
In addition to the changelog contents, you can also get some helpful info from the version numbers. WordPress and its plugins typically follow a version numbering format like MAJOR.MINOR.PATCH (e.g., 5.9.2). Here’s what the numbers mean:
- Major Updates (e.g., 5.0): These often introduce significant changes, like new features or redesigns, and may require testing to ensure compatibility.
- Minor Updates (e.g., 5.9): These include feature enhancements or improvements that are less likely to cause disruptions.
- Patch Updates (e.g., 5.9.2): These focus on bug fixes and security patches, and are usually safe to apply quickly.
Understanding version numbers can give you additional context about the scale and urgency of an update.
For example, if a plugin mentions fixing a compatibility issue with the latest WordPress core update, it’s a sign to ensure your core is up to date first. On the other hand, a note about deprecated functionality might signal it’s time to check if other tools or customizations on your site rely on that feature.
Keeping Up With Software Updates
In WordPress and open-source, code and content are constantly moving. Developers report bugs, security researchers identify vulnerabilities, and updates get pushed out. It’s a fast-paced ecosystem, and staying informed helps you keep your website safe and functional.
Here’s how you can stay on top of it all:
- Check for Software Updates Regularly: WordPress will alert you when updates are available in the Updates section of the admin. Pay attention to these.
- Backup First: Always back up your site before applying updates so you can restore it if something goes wrong.
- Test Updates: If possible, use a staging environment to test updates before applying them to your live site.
The relationship between WordPress updates and your website’s stability boils down to this: updates are opportunities. They’re a chance to improve functionality, fix problems, and secure your site against potential threats. By staying proactive with updates, you’re setting your site up for long-term success.
In our next article, we’ll explore how your hosting environment—including PHP and other server-side technologies—affects your site’s performance and security. Understanding this relationship will give you an additional layer of context on how WordPress software updates are not just self-contained in the web application. They have to work with your server code, too.
