KOffice underwent a major transition as part of the release of KDE Software Compilation 4 (''SC4''). Coinciding with the work on SC4, the KOffice team prepared a major new release – KOffice 2.0 – which used the new KDE Platform 4 libraries. Although version 2.0 was released in 2009, the release was labeled as a “platform release” which was recommended only for testers and developers, rather than production use, since the release was missing key features and applications from the previous stable release series.<ref>{{cite web|url=http://www.koffice.org/news/koffice-200-released/|archive-url=https://web.archive.org/web/20110607104948/http://www.koffice.org/news/koffice-200-released/ |archive-date=2011-06-07 |title=KOffice 2.0.0 released |publisher=KDE |date=28 May 2009 |access-date=1 May 2012 }}</ref>

This continued with version 2.1 in November, 2009. Regular end-users requiring a stable environment were still recommended by developers to use the stable 1.6 release series.<ref>{{cite web|url=http://www.koffice.org/news/koffice-2-1-released/|archive-url=https://web.archive.org/web/20110607143942/http://www.koffice.org/news/koffice-2-1-released/|archive-date=2011-06-07 |title=KOffice 2.1 released |publisher=KDE |date=24 November 2009 |access-date=1 May 2012 }}</ref> This version was also ported to Haiku<ref>{{cite web |url=http://tiltos.com/drupal/node/17 |title=KDE applications available for Haiku! |publisher=Tiltos.com |access-date=19 September 2013 |archive-url=https://web.archive.org/web/20130921061244/http://tiltos.com/drupal/node/17 |archive-date=2013-09-21 }}</ref> but the port was later not updated for newer KOffice versions.

In May 2010, version 2.2.0 was released and brought many new features and bugfixes. Kexi was integrated again. Kivio has not yet been migrated. A new framework for effects on shapes and a new import filters for the Microsoft Office Open XML formats that are used in MS Office 2007 and later got added.<ref>{{cite web|url=http://www.koffice.org/news/koffice-2-2-released/ |archive-url =https://web.archive.org/web/20110717204937/http://www.koffice.org/news/koffice-2-2-released/| archive-date=2011-07-17 |title=KOffice 2.2 Released |publisher=KDE |date=27 May 2010 |access-date=1 May 2012 }}</ref>
