Features and enhancements
Image lazy loading
Silverstripe CMS now lazy loads most images by default and includes some options to opt-out of this behaviour.
Image lazy loading defers the loading of images not in the viewport to improve the initial page load performance. Read more about (image lazy-loading)[https://web.dev/browser-level-image-lazy-loading/].

Most images will now get the
loading="lazy" attribute added to them. This includes:

SilverStripe\Assets\Image: lazy_loading_enabled: false
CMS authors can disable lazy loading on images added via the WYSIWYG editor in the "Edit image" panel by setting the new "Loading" field to "Eager".
