Hello,
here is the changelog for Preview 2025.2.1:

NEW Image Library: Even richer with Pexels
Finding the right image for your projects has never been easier. We merged free and premium image libraries to make searching easier thanks to the smart filters. Plus, we’ve integrated Pexels—joining Pixabay and Depositphotos—to offer an even broader and more user-friendly catalogue.

NEW Install your website like a PWA (Progressive Web App)
With just a few clicks, your website can now be installed as a Progressive Web App. It's like offering the same user experience as an App without having to develop one. Users can add the website directly in their smartphones' Home screen, without having to download it from an app store. This is definitely the smartest way to put your website... right in your users’ pockets.

NEW RTL support for multilingual websites
We’ve prepared WebSite X5 for the entire world. Thanks to RTL (right-to-left) settings, you can now create websites in languages written from right to left, such as Arabic or Hebrew. In many cases, you won’t have to start your projects from scratch, as the software automatically "mirrors" texts, menus, and content for natural reading.

NEW New Page Effects
Just like for the Objects, now you can take advantage of the new browser functions and add page transition effects too. There are many alternatives, and you can set the effect duration as well as the browser window color during the transition. The result? A more dynamic and engaging browsing experience.

(Page effects can currently be displayed only on Chromium-based browsers, such as Chrome, Edge e Opera, while other browsers such as Firefox and Safari currently do not support them)

NEW Zoom effect for Row Formats
By working on the row style, you can create sections that are both beautiful and functional. You can now also apply a Zoom effect to the images in the slideshow set as the background.

You can check the function to enable your website as a PWA in Step 1 - Settings ---> General Information, and RTL is also available here.

The Page effects can be activated from Step 3 - Map by clicking the Effect (star-shaped) icon after selecting a page.

Наконец-то, о чем я писал уже не помню сколько лет назад, появилось здесь (PWA). Ура, товарищи :)

@Axel im sorry too...

And like always the PWA is not finished and fully tested even into preview version !!!
