Schmitz Microsoft has released [1]Skype 6.4 with a new scheme for scrolling through your chat history. With the new 'infinite chat scrolling,' you'll be able to continually view more messages as you scroll upward through your history. You can also choose to jump to a specific time period by Control-clicking within the chat (your chat history will be indexed at your first login after installing the update). The release also redesigns the search UI within chat to be part of the chat view (and not open in a separate window), improves the way multiple contacts are sent and received, and adds support for Simplified Chinese, but it also removes custom chat styles for better design consistency across all OS clients.
