Messi.im V1.50 was approved by Apple a few hours ago. Here is a list of the new features:

• Group messages. Send messages to a group of friends/colleagues etc. Messages can include Video, picture and location
• Multi-Line Quick reply. The old quick reply has changed. Now you can write long messages here, because in shows multiple lines of text.
  Furthermore you can also add pictures, videos and location directly from here. No need to use the normal reply anymore.
• Speed improvements. Esspecially when opening a conversation with many messages.
• Bug fixes.
