xF2 Add-on Chat 2 by Siropu 2.5.1

Added XF's native reactions system in both rooms and conversations. It is disabled by default in Chat admin options (Enable reactions).

Added a new room option called "Room users" that allows you to give room access to certain users only. The users set there will join the room automatically and receive an alert about it. Users removed, will leave the room and get a notification. This option is permission based.

Added a new room option called "Repost in selected rooms" that allows you to automatically repost the messages posted in that room in other rooms.

Added a new user permission called "View current room messages after joining it" which allows you to hide older messages from the users who just joined the room. So basically they will be able to see only the messages posted from the time they joined the room. Permission is set to not view by default.

Added a new user permission called "Create room when starting a thread" which will add the option to create rooms when creating threads.

Added a new admin option called "Open internal links in a new tab" which will do what it says.

Added option to embed Chat outside XF in user list options for admins.
