Joomla 5.1 – is the version of the Joomla content management system that was released on April 16, 2024. It added new features, improved code security, and speed.

In the previous [free video tutorials](https://aleksius.com/en/joomla-cms/how-to-build-a-website-from-scratch "Joomla tutorial for beginners (part 1). How to build a website from scratch"), we created website on Joomla 4 from scratch. We used only free components. The result was a business website, which was uploaded to the hosting.

**The previously recorded video tutorials for Joomla 4 are almost completely relevant for the current version of Joomla 5.1.** At least this is valid on May 11, 2024.

In this article, we will talk about the «biggest» changes in Joomla 5.1 compared to version 5.0.

In the video you will see Joomla 5.1 on local server with PHP 8.1 and MySQL 8.0.30.

The article uses information from the official website – «[Joomla 5.1.0 and Joomla 4.4.4 are here!](https://www.joomla.org/announcements/release-news/5907-joomla-5-1-0-and-joomla-4-4-4-are-here.html "Joomla 5.1.0 and Joomla 4.4.4 are here!")» and «[What's new in Joomla 5.1?](https://magazine.joomla.org/all-issues/april-2024/what-s-new-in-joomla-5-1-1 "What's new in Joomla 5.1?")».

## <a id="changes-in-joomla-5-1"></a>Changes in Joomla 5.1

**«System – SEF» plugin update**. The new settings allow you to remove «index.php» from the URL, configure redirection of URLs with/without trailing slashes to the option you want, and also configure redirection to the main domain (image below).

 ![«System – SEF» plugin](https://aleksius.com/images/joomla/whats-new-in-joomla-5-1/system-sef-plugin.png) «System – SEF» plugin Previously, it was also possible to remove «index.php» from the URL in the general settings of Joomla, but in some cases it might not work.

**<a id="new-schema-org-plugins"></a>New Schema.org plugins: «Article» and «Custom»**. In [Joomla 5.0](https://aleksius.com/en/joomla-cms/whats-new-in-joomla-5-0-and-4-4#integration-with-schema-org "What's new in Joomla 5.0 and 4.4") you already have the opportunity to add structured data to the website. In version 5.1 were added «Schema.org – Article» and «Schema.org – Custom» plugins. «Schema.org – Custom» allows you to add any micro markup code you want in JSON format.

 ![New Schema.org plugins: «Article» and «Custom»](https://aleksius.com/images/joomla/whats-new-in-joomla-5-1/schema-org-custom.png) New Schema.org «Custom» plugin **<a id="admin-dark-theme-switch"></a>Admin dark theme switch (Dark Mode) and its update.** A dark admin theme was added to [Joomla 5.0](https://aleksius.com/en/joomla-cms/whats-new-in-joomla-5-0-and-4-4#joomla-admin-night-mode "What's new in Joomla 5.0 and 4.4"). But to enable it, it was necessary to change the mode in the operating system settings. Now you can go to the style settings of the «Atum» admin template and change the settings (picture below).

 ![Admin dark theme switch (Dark Mode)](https://aleksius.com/images/joomla/whats-new-in-joomla-5-1/joomla-admin-dark-mode.png) Admin dark theme switch (Dark Mode) Also, the theme switch appeared in the profile menu (picture below). If you don't have a switch in the profile menu, try going to the «Atum» admin template settings and just click on the save button.

 ![Joomla 5.1](https://aleksius.com/images/joomla/whats-new-in-joomla-5-1/theme-switch.png) Joomla 5.1 **Improved Articles availability checking**. In Joomla 4.1, a special tool was added to check the accessibility of content to users with disabilities («System - Joomla Accessibility Checker» plugin). In Joomla 5.1, this tool has been improved to detect and fix accessibility issues such as color contrast issues, missing tags, etc.

 ![«System - Joomla Accessibility Checker» plugin](https://aleksius.com/images/joomla/whats-new-in-joomla-5-1/system-joomla-accessibility-checker-plugin.png) «System - Joomla Accessibility Checker» plugin **Tutorial after installing Joomla 5.1**. In [Joomla 4.3](https://aleksius.com/en/joomla-cms/whats-new-in-joomla-4-3 "What's new in Joomla 4.3"), educational tours were added. And in 5.1, if you installed the CMS from scratch, you will see prompts when you first enter the admin.

**Other updates and changes:**

- Implemented The Update Framework (TUF). This will increase the security of the Joomla update process from the admin. TUF allows you to verify that the updates being downloaded have not been modified on the way from the update server to your website.
- Updated FontAwesome to 6.5.1 and TinyMCE to 6.8.3.
- Added regular expression validation for fields, allowing better control over the data that users enter.
- Modal windows in the admin area have been replaced.
- Improved 404 page for «Cassiopeia»
- SVG support has been added to the «Banner»
 
According to the [official website](https://developer.joomla.org/roadmap.html#4x "Joomla! Project Roadmap"), security updates will be released for Joomla 4.4 until October 14, 2025. The bug fixes of this CMS «branch» is planned until October 15, 2024. New features will no longer be added to Joomla 4. So, you should think about choosing the right time to update your site from Joomla 4 to 5.

Please note updating Joomla 3 to 4 is a much longer, complicated and expensive process than updating from Joomla 4 to 5.

**Considering minimal changes in terms of the admin interface and site management logic, all video tutorials and instructions previously recorded for Joomla 4 are relevant for Joomla 5.1.**

In the next video review we will talk about the changes in [Joomal 5.2](https://aleksius.com/en/joomla-cms/whats-new-in-joomla-5-2 "What's new in Joomla 5.2").
