WordPress 5.5: Diverse Array of Features for Developers, Editors & Other Users

WordPress 5.5 Update

WordPress 5.5 was released on August 11, 2020 and it comes with lots of improved and new features. This latest version of WordPress focuses on the speed, search and security of this CMS. The latest version includes 150+ enhancements, 1500+ changes to block-editor interface, 300+ bug fixes and other features aimed at improving the performance of WordPress 5.5.

Main Features of WordPress 5.5


Website Speed

WordPress 5.5 has made ‘Lazy-Load Images’ a default option for all websites with the inclusion of ‘loading attribute’ into the ‘img’ tag. This attribute is supported by almost all modern web browsers.

The images load slower than the plain text which increases the overall loading time of the web-pages. The ‘Lazy-Load Images’ option optimizes the images for a website and increases its loading speed and overall performance. When using the WordPress 5.5, only the immediately visible part of an image will be downloaded. The rest of the image will download as a user scroll’s down a web-page. This modification increases a website’s loading speed.



The XML sitemap is a file which lists all types of content of a website in XML format. This file is not visible to the visitors of a website. It assists all search-engines to effortlessly navigate/discover/index the content of a website, as the list of content is received in a machine-readable format.

All major WordPress SEO Plugins have built-in XML sitemap. However, WordPress 5.5 comes with a built-in sitemaps feature. This feature will create a new ‘sitemap index file’ that will be known as ‘wp-sitemap.xml’. It is going to contain the links to all sitemap files generated by a website.

The default Sitemap feature will support all types of posts along with the taxonomies (categories/tags/custom taxonomy) and author archives. Due to having this feature, a large number of people can quickly find any WordPress websites. It provides a better opportunity for the site-owners to engage, retain and convert the visitors into customers or subscribers.


Website Security

The powerful ‘updates’ management system increases the security of the WordPress websites with the release of WordPress 5.5. Using this feature, you can turn on auto-updates for all WordPress plugins and themes. You can change the configuration or use a third-party plugin to enable this feature and may use the admin dashboard for automatic updating.

  • To auto-update the plugins, you may go to the plugins page and select a plugin. You have to click on the ‘Enable auto-updated’ feature to ensure that the selected plugin becomes automatically updated.
  • You may enable auto-updates for themes in the similar manner. You may find a theme on the ‘Appearance » Themes’ page. You may click on a theme that you want to automatically update. After the selection, you may click on ‘enable auto-updates’ link.

Hence, a website will always run the latest available code. Users may even turn on/off the auto-updates feature for each installed plugin/theme based upon their unique needs or preference.
