Later on, service packs were released that contained a lot of fixes and improvements. The most significant differences of the new 'office' are the support of working with documents in the contributions, export of documents to PDF, new formats of source files (different from those used in Microsoft Office 2003) and completely redesigned toolbars in all components. The Office also received support for voice recognition (which is still available in Windows Vista) and handwriting. The package has received a pretty advanced graphical shell for its time, as well as new components, including the Microsoft Office Groove project collaboration tool and the Office SharePoint Server 2007 server platform. Microsoft Office 2007 is a version of the office suite that was born with the Windows Vista operating system.
