The beta for Office 2010 and SharePoint 2010 Service Pack 2 is available for download. For the details, see the Office Sustained Engineering blog post about the beta release.
You probably have your update process in place. But just in case, have a look at these resources:
- Distribute product updates for Office 2010
- Updates for SharePoint 2010 Products
- Deploy cumulative updates (Project Server 2010)
Remember, after you apply updates to SharePoint 2010 Products or to Office Web Apps running on SharePoint 2010 Products, run the SharePoint 2010 Products Configuration Wizard. Or, at a command line, on every server in the farm, run:
psconfig –cmd upgrade –inplace b2b -wait
Happy patch testing!
