Even if you already have experience with SharePoint 2007, the list of new features of SharePoint 2010 list is quite big. Lets take a look at them briefly.
1. Microsoft SharePoint Edition :
With the release of SharePoint 2010, the free WSS/ MOSS has gone and it has been replaced with SharePoint Foundation 2010.
SharePoint Foundation 2010 is the very basic version. It replaced Windows SharePoint Services from earlier version.
FAST Search Server 2010 for SharePoint: SharePoint Server 2010 with high-end Search Technology. It has lots of powerful features include recognizing departments or geographies, ability to tag meta data to unstructured contentm and more scalability.
SharePoint Server 2010 for Internet Sites, Standard Edition: To create Internet or intranet sites using the standard features of SharePoint Server 2010
SharePoint Server 2010 for Internet Sites, Enterprise Edition: more scalability and management functions than Standard Edition
SharePoint Online: Cloud Version of SharePoint
2. Enhanced SharePoint Designer: What’s new with SharePoint Designer 2010 is subject of another post. With re-designed User Interface, improved workflow and integration between various designers SharePoint Designer has gone far from just supporting tool. Microsoft has been steadily putting the ribbon UI in many of its products, including SharePoint 2010. The new designer also has a tabbed interface and provides breadcrumb navigation.
3. Range of Web Browser Support: SharePoint 2010 provides better experience for users accessing SharePoint sites with non-IE web browsers. But there some features are still inaccessible in non-IE browsers due their Active-X nature.
In SharePoint Foundation there are 11 instances of ActiveX controls. Some of major components availability is only with IE 8.0 including Multiple file uploads and datasheet view.
Also IE 6 is not supported officially. Chrome officially not declared, but it works fine.
4. New and Enhanced Collaboration Features
Microsoft has added and improved the collabration features including People Management, Blogs, Wikis, Social/Expertise Tagging and Calendar. Contents can now be tagged, bookmarked, and commented by an authorized user. That information can be used for content discovery.
A mash-up feature has been added where the calendar from Microsoft Exchange Server can be blended with SharePoint calendar.
