1. Voice and video calls on Android

Incoming call in MyChat for Android Video call in MyChat for Android

Now you can make calls on Android between Windows, Linux, macOS, and in a browser.

We also made convenient file downloader for various files in conference and private conversations:

2. Install MyChat directly from your server

Right after the launch of MyChat server all your users see the following WEB page:

MyChat Services

Share a link to this page with your co-workers for quick installation of MyChat client applications from your server.

You don't have to type the server address, register a user, and answer to the installer questions. All can be done in three steps.

3. New tool for system protocols

Every Admin knows that he can find any information about the issue in logs. MyChat Server stores logs with errors, various notifications, and warnings. We also added log levels:

Log levels on MyChat Server

At the bottom are the serious ones, everything is recorded, so logs becomes bigger. At midnight the server transfers the logs on the default level (in case if an administrator forgot to do that).

Previously, we used text files, but in v.6.8 we changed to the database. This improvement gives higher speed for data selection, you can make filters, receive help about errors (error links are located in log texts):

History of protocols on MyChat Server

Database file with system protocols does not "grow" uncontrollably — old entries are cleaned automatically. Database stores from 500 thousands up to 1 million of recent entries. In regular mode, if the VERBOSE logging is disabled, this can be enough for months.

4. Integration with GeoIP: determine user’s city and country

MyChat is used for support chats on internet market websites. People ask questions in a browser, directly on a website:

MyChat WEB support window

Now a support operator can determine website visitor’s country and city in his MyChat Client:

Information about a website visitor in MyChat Client

To make this feature work, you have to download the database with IP addresses and connect it to your server.

5. Integration with Telegram (improvements)

We made possible to register and activate Telegram users to MyChat automatically.

It works as follows: as soon as a Telegram user subscribes to messages from the bot, MyChat Server immediately registers an account in MyChat and links it with the Telegram account.

Auto-registration and auto-activation of Telegram user on MyChat Server

A person nickname, name and surname will be automatically written in MyChat user profile if this information is specified in the Telegram account.

Additionally, in the Admin interface, the name of your Telegram-bot is displayed, so you do not have to remember it when you need to subscribe new users.

6. Linux + macOS: program configuration

Main settings of MyChat Client are available in macOS and Linux:

Linux and macOS main settings

Use templates of server settings for MyChat users in macOS and Linux. All work the same way as for MyChat Client on Windows, though the interface a bit different.

7. Scripts, what’s new?

In each new MyChat version we add new functions of the built-in engine for writing extension programs.

In v.6.8 these are GeoIPGetFullInfoAsJSON and GeoIPGetQuickInfo functions to work with user geographical locations by their IP addresses. "Fetch" function — to work with strings and "mSetUserRoleID" to assign rights group.

Use mAddUserToCommonContacts to add a user to the tree-like common contact list.

mGetUsersListByEmailAndState and mGetUsersListByEmailAndState functions are used to get lists of users by nicknames/emails and network statuses.

8. Blocking by HardwareID

HardwareID — is a special string, unique for computer, on which MyChat Client is running.

This string depends on the type of microprocessor and hard drive model. You can check information about user HardwareID in the "User list" section of Admin Control Panel.

Now you can block user computers or smartphones by this unique parameter in the tool "Filters", "HardwareID filters":

Blocking by hardwareID on MyChat Server

9. Limit the number of registrations from IP/MAC/HardwareID addresses

To avoid possible attacks or fake registrations we made this feature is for public servers that are opened in the Internet.

By default the protection is enabled, the maximum number of identical IP — 100, for MAC/HardwareID — 10 pcs.

10. No conflicts with Windows Firewall

MyChat Server — is quite difficult network application. We are trying to make it as friendly to admins as it possible. We understand that you have enough tasks and work apart from corporate messenger.

In the new version the server adds itself to the Windows Firewall exception list automatically:

Modern antivirus software, that filters traffic, usually pays attention to Windows Firewall and its settings, so administrators won’t have additional problems when configuring MyChat Server.

11. Various improvements

We added the context menu to the announcement board for copying and pasting, and made more space for text:

Context menu in MyChat announcement board

Use "Ctrl+Enter" for quick message publication.

When you receive files in the chat, MyChat Client will remember the last folder, where they were saved. By default files are saved to the "C:\Users\%USERNAME%\Documents\MyChat\" folder that has the sender’s name. However, you can change the folder for a specific user, and the program will remember it:

If you need to save files from all users to the default place (ignoring personal folders that have ever been selected), then just uncheck this box.

In the server settings, you can set a folder for user files and work protocols. We made a separate section for folder settings to avoid searching them in the whole interface:
