1. Multilogins

---

You asked and we delivered. Now it is possible to be online on several devices simultaneously. For example, in Windows application and MyChat for Android:

All technologies work as usual: message exchange, files and images transfer, calls, broadcasts, and Bulletin board (announcements board). Multilogins work in Windows, Android, Linux, macOS, and WEB.

When Android applications are not active, PUSH notifications is on (do not forget to give the internet access to your MyChat Server).

Remember, each connection requires a connection available in your license. Manage active connections on the Admin Panel, the section "Online users".

Some changes made for the system of downloading files from the server. Now files downloaded directly on the disk avoiding RAM consumption, independently from the server.

Finished the system for viewing network information and active processes of online users:

A new tool for inviting users to conferences in MyChat for Android:

New settings for a quick closing of private dialogues and conferences by mouse double-clicking, and mouse middle-clicking:

As usual, these settings can be included in a template on the server, to avoid adding them manually on each computer but applying them automatically for groups.
