Some good reasons to read Changelogs before updating plugins and themes on WordPress

10 valid reasons to stop and read the changelogs rather than update without worries.



WordPress, the popular content management system (CMS), boasts great ease of use, accentuated by the wide range of plugins and themes available. These add-ons, constantly developed to introduce new features, fix bugs, or address security issues, are a key part of the WordPress ecosystem. However, there is a widespread and dangerous behavior among many WordPress site administrators: the habit of updating plugins and themes without first reading the changelogs.

This superficial approach, often motivated by the search for efficiency or blind faith in the ability of updates to automatically improve the site, can lead to unexpected consequences. Updating without understanding exactly what changes will be made is equivalent to browsing by sight, exposing the site to potentially serious risks. For example, an update could introduce changes that conflict with other plugins or themes used, causing malfunctions or even making the site inaccessible. Additionally, unanticipated changes in user interface or functionality may disorientate users or alter the customer experience in unexpected ways.

This article explores why it's essential to read changelogs and how they can help you keep your site safe, efficient, and up-to-date.

1. Understand the Changes Made

Understanding the changes made in each update is critical to effectively managing a WordPress site. Changelogs aren't just a list of fixes and improvements; they represent a detailed map that guides site administrators through the maze of continuous updates.

When a plugin or theme is updated, it may include new features, UI improvements, performance optimizations, or API changes. For example, an update might introduce a new caching feature to improve site performance, or it might change the way a plugin interacts with the WordPress database. Without reading the changelog, you may not be aware of these changes and therefore not take full advantage of them or, worse, you may encounter unexpected problems because you were not informed of an important change.

Additionally, changelogs often include notes on the impact of changes. For example, an update may require changes to your site's configuration or may be incompatible with older versions of WordPress or PHP. This information is essential to avoid service interruptions and to ensure that your site remains functional and secure.

2. Prevent Compatibility Issues

One of the biggest risks in updating plugins and themes on WordPress is the possibility of introducing compatibility issues. These problems can range from minor inconveniences, such as a design element not displaying correctly, to serious malfunctions that can make your entire site inaccessible.

By carefully reading changelogs, you can identify in advance whether an update might conflict with other components of your site. For example, if a plugin update changes how it handles data submitted through a form, this could affect other plugins that interface with the same form. Knowing this in advance allows you to test the update in a staging environment, thus evaluating the impact of the changes before applying them to the live site.

Additionally, understanding changes helps maintain a balance between keeping the site up to date and ensuring all components work together smoothly. This is especially critical for complex or highly customized sites, where a small change can have a significant impact.

3. Maintain Site Security

Security is perhaps the most critical aspect of running a WordPress site. Plugin and theme updates often include fixes for security vulnerabilities discovered by developers or researchers. Ignoring this information can expose your site to significant risks, such as hacking attacks or data leaks.

Changelogs provide crucial details on what security issues have been addressed in an update. For example, a changelog might indicate that a Cross-Site Scripting (XSS) vulnerability has been patched. With this knowledge, you can understand the urgency of the update and act accordingly to protect your site from potential exploits.

Additionally, regularly monitoring changelogs allows you to be proactive about your site's security. You will be able to identify common patterns or vulnerabilities in the plugins and themes you use, allowing you to make informed decisions about additional security measures that may be necessary, such as implementing firewalls or scanning systems for malware.

4. Schedule Updates

Planning updates is a fundamental aspect of managing a WordPress site, especially for companies that deal with hosting and systems engineering, such as Managed Server SRL. A careful reading of the changelogs allows you to understand not only the 'what' and 'why' of the updates, but also the 'when' is the most appropriate to implement them.

For example, a changelog might indicate that an update to a popular theme requires special attention due to breaking changes in the user interface or code structure. This may take time to test and verify compatibility with existing site elements. In this case, you may decide to postpone the update until a period of lower traffic on the site, to minimize the impact on users and customers.

Additionally, consciously scheduling updates helps avoid disruption to critical services. For e-commerce sites, for example, updating during a period of high sales may not be ideal. Changelogs can help identify which updates are urgent for security and which can wait for a more opportune time.

5. Inform Users or Customers

If you manage a site on behalf of clients or a community of users, it's important to communicate changes made through updates. Changelogs provide the information needed to create clear and precise communications about what will change on the site.

For example, if an update introduces new features or changes the way existing ones work, your customers or users will need to be informed in order to make the most of these new features. Effective communication based on detailed changelog information can increase user satisfaction and reduce confusion or frustration.

Additionally, if there are any updates that affect privacy or security, such as changing data collection policies, it is critical to inform users in a timely and transparent manner. Changelogs provide you with the information you need to do so accurately and in compliance with current regulations.

6. Troubleshooting

After applying an update, you may experience some issues on the site. Having prior knowledge of the changelog allows you to quickly identify whether a specific issue is related to the recent update. This is especially useful in troubleshooting situations, where time is of the essence.

For example, if you notice a decrease in site performance or a specific feature malfunctioning, you can consult the changelog to see if these problems have been reported in relation to the latest update. This targeted approach to troubleshooting speeds up the troubleshooting process, allowing you to focus on the specific changes that may have caused the problem.

Additionally, understanding the update details can help you communicate more effectively with tech support or plugin/theme developers. You'll be able to provide detailed information about which version you're using and what recent changes may have affected your site, making it easier to find a solution.

7. Learning and Professional Growth

For developers, system administrators and IT professionals, changelogs represent a unique opportunity for learning and professional growth. They offer first-hand insight into current development practices, architectural choices, and strategies for addressing common problems in the WordPress world.

By reading changelogs, you can learn how plugin and theme developers respond to specific technical challenges, such as performance management, version compatibility, or security. This can stimulate ideas for your own projects or provide innovative solutions to problems you might encounter in the day-to-day management of client sites.

Additionally, keeping up to date with the latest technology updates and trends is essential in a rapidly evolving field like IT. Changelogs, in this sense, are a precious source of knowledge that can contribute to continuous professional development.

8. Contribute to the WordPress Community

Reading changelogs not only benefits the management of your own site or client sites, but can also provide insights to actively contribute to the WordPress community. Understanding the details of updates uniquely positions you to provide constructive feedback to developers, report bugs, or participate in discussions about the future direction of a plugin or theme.

For a hosting and systems company like ours with a deep technical knowledge of WordPress and its dynamics, there is an opportunity to share experiences and advice with the community, perhaps through blogs, forums or direct contributions to projects. This not only helps improve the tools you use every day, but also strengthens the company's reputation and authority in the WordPress ecosystem.

9. Performance Optimization

Performance optimization is a key aspect of successful websites, and changelogs can be a valuable source of information on how updates may affect site performance. It's critical to understand which updates offer improvements in speed, cache efficiency, reduced load times, and resource optimization.

For example, a changelog might detail how an update to a popular plugin reduces its impact on server resources or improves integration with advanced caching systems. This information is essential for making informed decisions about updates that can help maintain or improve site performance.

10. Preparation for Future Developments

Finally, Changelogs often provide clues to future developments, new features, or directional changes in a plugin or theme. This information can be extremely valuable in planning ahead and preparing for changes that are on the horizon.

For example, if a changelog mentions upcoming support for a new technology or future incompatibility with previous versions of WordPress, this is crucial information to start planning updates or changes to your managed site(s). Anticipating these trends means being able to offer customers cutting-edge solutions and proactive advice, always staying one step ahead in technology and website management.


In conclusion, reading changelogs before updating plugins and themes on WordPress is an essential practice that offers numerous advantages. It provides a deep understanding of the changes you make, helps prevent problems, improves site security and performance, and keeps you informed about the latest trends and developments. For any hosting and systems company, such as Managed Server SRL, which focuses on web performance and the management of CMS such as WordPress, integrating changelog reading into the site management routine can mean the difference between a performing site and one that struggles with ongoing issues and security vulnerabilities.
