History
As KPresenter
Reginald Stadlbauer began development of KPresenter in 1997. 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. Versions 1.1 followed in 2001, 1.2 in 2002, 1.3 in 2004, 1.4 in 2005, and 1.5 and 1.6 both in 2006.
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.
This continued with version 2.1 in November, 2009.

Why this record matters
The phrase “presentation program” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 27, 2025. The linked authority identifier is Q2073057. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2014, 1997, 2000 and 2001.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
