Update WordPress, Themes, Plugins
You do need to update WordPress , it’s Plugins and Themes. Keeping your website up to date goes a long way to ensure it works seamlessly. It helps to keep the wheels turning without unnecessary friction.
From time to time WordPress introduces new code into the core files. These are intended to make the whole system run better. They introduce new capabilities, fix compatibility issues and fine tune security. Depending on your settings the WordPress updates will auto install or alternately appear in your dashboard for you to manually install.
In the case of major updates, you may need to manually click to install even if you have set to auto. This is just a safe guard giving you opportunity to do any housekeeping or backup first.
Just as WordPress has updates, so do your installed plugins. WordPress makes the core file updates available to developer before release to the general public. They do this to give plugin developers and authors time to test their plugins with the changed WordPress core files. They can then decide to release updates for their plugins to accommodate the WordPress changes if necessary. This is how they stay ahead of the game. So when we update WordPress on our sites, their plugins are ready to go.
While there may not be any conflicts to fix, many plugin authors may take the opportunity to release any incremental updates they were working on. It also allows for their plugin to report compatibility with the latest version of WordPress.
