What's new on gmail?

Literally half an hour ago, I went into my Google box and saw an interesting item in the upper right.
Here is this: New! Group chat
Below is something like a translation of the page to which the link leads.
Sorry for the dupe, I personally have not seen this topic here, apparently missed.

Group chat

Group chat allows you to communicate with many of your friends at the same time. There are no longer any restrictions on the number of people with whom you can communicate at the same time and everyone can invite new ones.

To get started, follow these steps:

1. Start a conversation with one person from your contact list.
   After that, click "Options" in the lower left corner of the chat window and select "Group chat."
   In the field “Invite to chat” enter the name of one or several friends you want to invite to chat.
   To end such a chat as for a normal chat, click the X button in the corner of the window. Other members of the chat will receive a message stating that you are logged out. If you need to return, you will need an invitation from anyone who is still in the group chat. Group chat will be interrupted only when all participants leave it.
   

   New smilies

   
   Stop using :) (why! - my comment) and transfer your emotions to your interlocutors more clearly!
   
   To use smiles, simply do one of the following:
   
   • Write the desired sequence of characters and press Enter.
     Click on the button in the form of a small smiling face in the lower right corner under the text entry field. A menu will appear, there you can choose the smilie style you like and the smilie itself. Now there are 3 styles: round, square or standard smilies.
