History
As KPresenter
Reginald Stadlbauer began development of KPresenter in 1997.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> The first official release of the KOffice suite was on October 23, 2000 when it was released as part of K Desktop Environment 2.0.<ref name=KDE2.0>Template:Cite web</ref> Versions 1.1 followed in 2001,<ref>Template:Cite web</ref> 1.2 in 2002,<ref>Template:Cite web</ref> 1.3 in 2004,<ref>Template:Cite web</ref> 1.4 in 2005,<ref>Template:Cite web</ref> and 1.5<ref>Template:Cite web</ref> and 1.6 both in 2006.<ref>Template:Cite web</ref>
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>Template:Cite web</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>Template:Cite web</ref> This version was also ported to Haiku<ref>Template:Cite web</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>Template:Cite web</ref>
In mid-2010, following disagreements between KWord’s maintainer Thomas Zander and the other core developers,<ref name="LWN-KOffice">Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref> KPresenter was renamed Calligra Stage.<ref>Template:Cite web</ref> The KWord maintainer forked the KPresenter presentation tool to create KOffice Showcase.
KOffice 2.3, released 31 December 2010,<ref>Template:Cite web</ref> along with subsequent bugfix releases (2.3.1–2.3.3<ref name="KOffice2.3.3">Template:Cite web</ref>) was still a collaborative effort of both the KOffice and Calligra development teams.<ref name="LWN-KOffice"/><ref>Template:Cite web</ref>
KOffice Showcase 2.4 never materialized in release form. Template:As of KOffice was declared unmaintained by KDE.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
As Calligra Stage
On 18 May 2011 the Calligra team began releasing monthly snapshots while preparing for the release of Calligra 2.4.
The first version of the Calligra Suite for Windows was released on 21 December 2011. The package is labeled as “highly experimental” and “not yet suitable for daily use”.<ref>Template:Cite web</ref>
The Calligra team originally scheduled to release the final 2.4 version in January 2012<ref>Template:Cite web</ref> but problems in the undo/redo feature of Words and Stage required a partial rewrite and caused a delay.<ref>Template:Cite web</ref> Calligra 2.4 was released on 11 April 2012.<ref name="2.4 release">Template:Cite web</ref>
Calligra 2.4 launched with two mobile-oriented user interfaces: Calligra Mobile<ref>Template:Cite web</ref> and Calligra Active. Calligra Mobile's development was initiated in summer 2009 and first shown during Akademy / Desktop Summit 2009 by KO GmbH as a simple port of KOffice to Maemo. Later Nokia hired KO to assist them with a full-fledged mobile version, including a touchscreen-friendly user interface which was presented by Nokia during Maemo Conference in October 2009.<ref>Template:Cite web</ref> The first alpha version was made available in January 2010.<ref>Template:Cite news</ref> Along with the launch of the Nokia N9 smartphone, Nokia released its own Poppler and Calligra-based office document viewer under GPL.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
Calligra Active was launched in 2011 after the Plasma Active initiative to provide a document viewer similar to Calligra Mobile but for tablet computers.<ref name=Calligra24Beta>Template:Cite web</ref>
Jolla continued Nokia's efforts on a smartphone version. In 2013 Jolla launched Sailfish Office.<ref name="Sailfish">Template:Cite web</ref> Sailfish Office reuses the Qt Quick components from Calligra Active.<ref name="Calligra Gemini"/>
In September 2013 a merger of Krita and Krita Sketch, named Krita Gemini, was launched on Windows 8.1. Development was funded by Intel to promote 2in1 convertible notebooks.<ref>Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref>
In April 2014 Intel and KO GmbH extended the promotion deal to Gemini versions of Stage and Words.<ref name="Calligra Gemini Linux"/> On 28 August 2014 the first snapshot of Calligra Gemini was released by KO GmbH for Windows.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> On 21 November 2014 KDE announced that Calligra Gemini would officially be released as part of Calligra 2.9.<ref name="Calligra Gemini"/> As with Krita, this Gemini release adds a touchscreen interface to Words and Stage and users can switch between desktop and touch mode at runtime. Calligra Gemini is a continuation of Calligra Active and Sailfish Office developments but with added editing capabilities.<ref name="Calligra Gemini"/> On 19 October 2014 a Linux version was presented.<ref name="Calligra Gemini Linux"/>
