Main news of Nextcloud Hub 21

In this new version a new high-performance backend has been proposed for the File Sharing and Storage subsystem (Nextcloud Files), which significantly reduces polling load periodic status by desktop clients and web interface.

Besides that added a mechanism to send notifications about file changes, comments, calls, chat messages, and other storage-related events that support direct customer connection to customer.

The proposed system of notifications to the server allowed to increase periodic health polling period from 30 seconds to 5 minutes and reduce the number of connections between the servers and the client by 90%. The new backend code is written in Rust and is offered as an option.
Performance optimizations have been made to reduce page load time, speed up database queries, and reduce server load.

In some situations, it was possible to increase the responsiveness of the interface up to two times. Unified search optimization has been performed, in addition to being compatible with the PHP 8 interpreter, which was introduced by the JIT compiler.

The optimizations implemented in the server components related to caching, working with the database and the organization of storage, in combination with the new backend, allowed to increase the number of clients served up to 10 times.

On the other hand, it is mentioned that added a new whiteboard collaboration app which allows multiple users to draw shapes, write text, leave notes, upload images, and create presentations. Files created in Whiteboard are saved together with normal files, but are available for joint editing.

As well, chat visibility settings have been implemented, which can be used to provide access, even to invited participants, without the need to add to the chat.
