- It is no longer necessary to hold the cmd (Apple) key when clicking urls in the chat window.

H264 Usage Note
H264 is very efficient in terms of bandwidth usage, and will give vastly improved results in both frame-rate and image quality when compared to MJPG or H263.
This codec uses a significant amount of CPU when the picture size and quality are set to anything better than their default of Normal.
If you choose to use this codec, users with VChat 1.1a6 (or earlier) will not be able to see your video. Windows users will not be able to view your video either.
