Notes on Sp11

Hi,

We are trying to upgrade the server with SP11..but before that we want to know the pros and cons of it..i mean what is SP 11 providing more than SP10? How stable it is?

I am unable to find in service market place where the release notes about SP11 stability is present. can anybody

please help me with the note number or URL.

If I am not mistaken I know where the patches can be downloaded .I want notes about its advantage alone.

Thanks in advance,

Regards,
