With Joomla! 4.0, a completely rewritten and better version of the media manager was implemented.The major feature of Joomla 4.1 will be an even more improved media manager. Right now the media manager is mainly used for uploading images, but we want to extend it to a true media managing facility. Consider image management with different sizes and metadata, handling and specifically playback of video and audio and support for documents.
