Just a jhatka like update happened on whatsapp. Whatsapp has been done limitation on sharing messages over groups or chats. Now you can only share a message to 5 Groups or Chats at a time. You have to work hard from now to share in more groups. Before you were able to share in 256 groups or chats. This will be bad for them who are using whatsapp for promotion purpose. Still there may be trick which should came in future to avoid this or may be whatsapp can take more several actions in future.
