WordPress 5.4 Release Date
The official date of release for WordPress is 31st March 2020 and a number of features could be released with this update, one of them will be the lazy-loading effect.According to WordPress:
“The implementation seeks to enable lazy-loading images by default, providing the loading attribute with value lazy on the following img tags:- Images in post content
- Images in post excerpts
- Images in comments
- Images in text widget content
- Individual images rendered via wp_get_attachment_image()
