A few weeks early, so this was a very nice surprise. We’ll get some precious time before SharePoint Conference 2012 in Las Vegas to learn what’s changed, and if things are more stable now than with the betas.
After a few hours of running with Office 2013, I have to say that Outlook 2013 and Lync (client) 2013 are much more faster and stable now. Lync 2013 (Preview) crashed against Lync Online constantly, and so far – no issues!
I’m still missing Project Server 2013, although Project Professional 2013 (the client, that is) seems to be available.
You can get all these sweet bits at MSDN and/or Technet.
