1. What is new in common Bulletin board?

New simplified design:

Simplified design of the MyChat Bulletin board

New simplified design. Fast content filter and sorting are added. Solved problems with encoding when copying text from the board to the clipboard.

In MyChat Client settings you can specify whether to display the bulletin board window on top of all windows or not; whether to notify in the tray with a flashing sign or pop-up window or not.

Настройки показа доски объявлений MyChat Client

If the user has a terminal session open on the whole screen, the bulletin board displays correctly on top of all windows.

We recommend you to configure the setting for all users remotely via the server in the "Tools" -> "Settings templates" section.

2. View active process in real time

Redesigned tool to view user active processes and computer or smartphone system information:

MyChat Client tool to view user active processes and computer or smartphone information

Double-click or Enter works on some elements of the list.

  1. IP — GeoIP service opens;
  2. NetName — NETBIOS computer name opens in Windows Explorer. You can check the list of open system folders (shares) ;
  3. Reflink — if it is a websupport user, a browser opens with a page from which this person transferred into the support chat on your website.

You can set rules for data visibility (who can see it and can't) in the user permission groups on the server: "Rights control", "Permission groups", "Profile", "View information".

Besides, there is a complete technical information about all user connections in his profile view:

You can check here a version, application type, time and date of the last connection, IP and MAC address, encryption used, operating system type, referral links and UserAgent browser (for websupport), local network interface lists, NetBIOS computer name and HardwareID.

3. MyChat Guest improvements to invite people in MyChat via email

If you need to talk comfortably with a person in chat then use MyChat Guest:

However, the server creates a new MyChat account for all users who receive an invitation. Previously, if an invitation was sent a couple of times, then whenever you click on the link the server created a new user account.

Because of this issue, the messages history with the same user in the chat become divided along several users with the same email address but different UIN.

The server has become smarter and tries to determine that a user with this e-mail was connected to the server before via MyChat Guest and he no longer needs to create a new account. The main criteria are matching e-mail and Gusts or WebGuests permission group.

4. New features of scripting language

A lot of functions to work with checksums, hashes, base64/UU/URL and HTTP GET encoding and decoding:

5. Various improvements

Sometimes happens that users are connected via slow connection channels and update automatically from your MyChat Server.

It turned out that if there are a lot of people on the server then external Internet channel blocks during the update, so it becomes necessary to limit users somehow. Let them update longer, but not all at once.

We made a special option on the server to limit simultaneous downloads:

Enabling a limit for simultaneous downloads on the MyChat Server

In MyChat for Android you can view protocols to solve problems instantly:

View logs in MyChat for Android

We also added a setting to disable IP address in tokens when login into MyChat Services without a password:

Disabling IP address in tokens when entering MyChat Services

Many users use tokens to enter the Admin panel, Kanban board or forum directly from MyChat Client:

Entering the Admin panel, Kanban board and forum

When you select one of these options, MyChat requests a special one-time token from the server to enter the service you need.

The server checks the access rights, and if everything is okay, it sends you a token in response. MyChat Client opens a browser with the received link, and you enter the Admin panel, Kanban board or the forum automatically without entering a login and password.

At the moment of entering the WEB service, MyChat Server checks the token for validity and also looks from which IP address you try to enter. If this IP address does not match the address from which the token is requested, then the authorization attempt is ignored, and the token is destroyed.

It seems that everything is correct, but there is a problem if your browser works via a VPN or proxy. Then your MyChat Client and browser IP will not match. To avoid this limitation, we made the setting for disabling IP address control in the given one-time tokens.

This setting is enabled by default with a performing monitoring because a disabling of this setting is a deliberate lowering of safety requirements.
