Calligra Stage

[13] KOffice underwent a major transition as part of the release of KDE Software Compilation 4 (SC4).

[17] In mid-2010, following disagreements between KWord’s maintainer Thomas Zander and the other core developers,[18][19][20] KPresenter was renamed Calligra Stage.

[21] The KWord maintainer forked the KPresenter presentation tool to create KOffice Showcase.

[27] The Calligra team originally scheduled to release the final 2.4 version in January 2012[28] but problems in the undo/redo feature of Words and Stage required a partial rewrite and caused a delay.

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.

[37] Sailfish Office reuses the Qt Quick components from Calligra Active.

[38][39][40] In April 2014 Intel and KO GmbH extended the promotion deal to Gemini versions of Stage and Words.

[4] On 28 August 2014 the first snapshot of Calligra Gemini was released by KO GmbH for Windows.

[3] 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.
