I posted my short review
Here but still lemme post the contents here:
I suggest, not to install this version! I tried it last night and
had these problems:
- Script error, when i click on the links in the messenger window
- Crashes (only once for me, but other ppl expierence this more)
- Heavy on system resource (even more than the earllier version)
More reasons: 
- That hidden emoticons program can't be used
- The interface looks bad when comapred to ealrier version, IMO
- It's a 8.5mb setup.
On the positive note:
- The file transfer thing is better and improved very much, i just tried sending/recieving files and it went on well...
- The voice/ internet call thing sounds good, but i dont think it will be much of a use to me also there are better tools for it like spype
Overall it needs improvement, but u guys decide for yourself and their is nothing wrong in trying this out....
