In case of you missed it, SkyDrive Pro is the “professional” SkyDrive client to keep offline your SharePoint content.
It has been introduced with SharePoint 2013 and Office 2013 and so was only available through Office 2013 editions (Office 365 Pro Plus, Office 365 Small Business Premium or Office 2013 Pro Plus).
Since yesterday (May 21st), Microsoft has now provided it as standalone and free products, allowing you to keep your ‘old’ Office version (2007 or 2010) and anyway being able to use SkyDrive Pro.

DON’T forget, for those who have Office 2010 installed, you are still able to use SharePoint Workspace as there is some limitations with SkyDrive Pro – see my post http://blog.hametbenoit.info/Lists/Posts/Post.aspx?ID=412
