[SOLVED] Different versions

I think Asterisk will suit my needs regarding finding cheap connectivity thru the web. What I noticed though is that if I look to my FreeBSD ports, there is a 1.4 version available, and thru download from this website, there is also a 1.6 version available. Can someone tell me what the difference is between these two versions?

thanks for sharing,
