You can stop holding your breath, as the release date for Service Pack 2 for Office 2007 was announced: April 28th is the big day! Mark that day down in your calendars and get those browsers warmed up.
There are, of course, numerous fixes, enhancements, etc for all the products, but since this blog covers SharePoint, I wanted to point out just a small part of what's coming up:
Windows SharePoint Services 3.0 SP2 and Microsoft Office SharePoint Server SP2:
SP2 offers support for a broader range of Web browsers.
Substantial improvements to Forms-based authentication.
Windows Server 2008 SP2 and Windows Server R2 will be supported on their release.
Enterprise Content Management (ECM):
A few more tidbits about what’s coming down the pipeline for the client side can be found on the Office Sustained Engineering blog. Of course, I am working with a beta engineer to get a few sneak peeks at new features, and will be posting a lot about that in the near future.
