01 | security
WordPress is the most popular content management platform world-wide. And when you keep WordPress updated, it’s also among the most secure. But if you neglect the updates, your WordPress website is at risk from attacks, vulnerabilities and inconveniences. Hackers can search for websites running the older version, and you may become a victim of a sophisticated attack. Not just WordPress itself, plugins can also be exploited by hackers. So you need to make sure that all your WordPress plugins, themes, and the core itself is always up to date.
02 | benefit from new features
Each major WordPress release comes with new features and changes to the software. So if you were using an older version of WordPress, then your WordPress experience would be a lot different than someone using the latest version.
03 | speed
WordPress developers are always trying to make things faster. Each new release comes with several performance improvements that makes WordPress run faster and more efficient. Since speed is a huge factor in SEO, you should definitely keep your WordPress updated to ensure maximum performance benefits.
04 | 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.
05 | 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.
