History
Work on Plan was started in 2004 under the name KPlato (K PLAnning TOol). The first release was in April 2004 as part of KOffice 1.5. In 2010 KPlato 2.2 was released with KOffice 2.2. Among its new features was the possibility to use Kexi's new Report Designer that replaces KOffice 1.6's Kugar application.{{cite web |url=http://www.koffice.org/news/koffice-2-2-released/ |title=KOffice 2.2 Released |publisher=KOffice.org |date=2010-05-27 |access-date=2012-05-01 |url-status=dead |archive-url=https://web.archive.org/web/20100728171705/http://www.koffice.org/news/koffice-2-2-released/ |archive-date=2010-07-28 }}{{cite web|url=http://community.kde.org/Kexi/Releases/Kexi_2.2#Reports |title=Kexi/Releases/Kexi 2.2 |publisher=Community.kde.org |date=2012-04-27 |access-date=2012-05-01}} Later that year, the software changed its name from KPlato to Plan and migrated from KOffice to Calligra.
