Microsoft have recently released the latest update for SBS 2011 Standard. You can find the details here.
What is interesting is that this includes a fix for SSL certificate requests to prevent the internal domain name eg mycompany.local from being included in the SSL certificate request that you would send to your SSL Certificate Provider. They have had to make this change due to changes that many of the SSL providers are making in refusing to issue SSL certificates for internal domain names.
Note that there is no update for SBS 2008 at all, so if you are running SBS 2008 and need to renew your certificate, you’re stuck and need to do it manually rather than using the SBS 2008 certificate request wizard.
