Deprecated modules:
The KDE project provides unofficial support for Qt 5.15 in the form of a collection of bugfix patches, most of which are backported from Qt 6. [5] As KDE has a policy of not assigning version numbers to their patches, Linux distributions use ad-hoc schemes when using this fork of Qt5: OpenSUSE, for example, calls its June 2021 version "5.15.2+kde200". [57]
Qt 6.0 was officially released on December 8, 2020. [58]

KDE is an international free software community that develops free and open-source software. As a central development hub, it provides tools and resources that allow collaborative work on this kind of software. Well-known products include the Plasma Desktop, KDE Frameworks, and a range of cross-platform applications such as Amarok, digiKam, and Krita that are designed to run on Unix and Unix-like operating systems, Microsoft Windows, and Android.
Qt is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed.
The Qt Company is a software company based in Espoo, Finland. It oversees the development of its Qt application framework within the Qt Project. It was formed following the acquisition of Qt by Digia, but was later spun off into a separate, publicly traded company.
Gambas is the name of an object-oriented dialect of the BASIC programming language, as well as the integrated development environment that accompanies it. Designed to run on Linux and other Unix-like computer operating systems, its name is a recursive acronym for Gambas Almost Means Basic. Gambas is also the word for prawns in the Spanish, French, and Portuguese languages, from which the project's logos are derived.
Kubuntu is an official flavor of the Ubuntu operating system that uses the KDE Plasma Desktop instead of the GNOME desktop environment. As part of the Ubuntu project, Kubuntu uses the same underlying systems. Kubuntu shares the same repositories as Ubuntu and is released regularly on the same schedule as Ubuntu.
Maemo is a software platform originally developed by Nokia, now developed by the community, for smartphones and Internet tablets. The platform comprises both the Maemo operating system and SDK. Maemo played a key role in Nokia's strategy to compete with Apple and Android, and that strategy failed for complex, institutional and strategic reasons.
Qt Creator is a cross-platform C++, JavaScript, Python and QML integrated development environment (IDE) which simplifies GUI application development. It is part of the SDK for the Qt GUI application development framework and uses the Qt API, which encapsulates host OS GUI function calls. It includes a visual debugger and an integrated WYSIWYG GUI layout and forms designer. The editor has features such as syntax highlighting and autocompletion. Qt Creator uses the C++ compiler from the GNU Compiler Collection on Linux. On Windows it can use MinGW or MSVC with the default install and can also use Microsoft Console Debugger when compiled from source code. Clang is also supported.
Lubuntu is a lightweight Linux distribution based on Ubuntu and uses the LXQt desktop environment in place of Ubuntu's GNOME desktop. Lubuntu was originally touted as being "lighter, less resource hungry and more energy-efficient", but now aims to be "a functional yet modular distribution focused on getting out of the way and letting users use their computer".
PySide is a Python binding of the cross-platform GUI toolkit Qt developed by The Qt Company, as part of the Qt for Python project. It is one of the alternatives to the standard library package Tkinter. Like Qt, PySide is free software. PySide supports Linux/X11, macOS, and Microsoft Windows. The project can also be cross compiled to embedded systems like Raspberry Pi, and Android devices.
rekonq was a lightweight, QtWebKit-based web browser developed inside the free software project KDE. It is the default web browser of Chakra GNU/Linux, and was formerly of Kubuntu. rekonq has been officially included in KDE Extragear since 25 May 2010. In contrast to Konqueror, a web browser and file manager also developed by KDE, rekonq aims to be a standalone and simple web browser. Its code was initially based on Qt Development Frameworks' QtDemoBrowser and is developed on KDE Projects' Git repository.
LightDM is a free and open-source X display manager that aims to be lightweight, fast, extensible and multi-desktop. It can use various front-ends to draw the user interface, also called Greeters. It also supports Wayland.
Mer was a free and open-source software distribution, targeted at hardware vendors to serve as a middleware for Linux kernel-based mobile-oriented operating systems. It is a fork of MeeGo.
Falkon is a free and open-source web browser developed by KDE. It is built on the QtWebEngine, which is a wrapper for the Chromium browser core.
Maliit is an input method framework for computers with particular focus on implementing virtual keyboards. Designed mostly for touchscreen devices, Maliit allows the inputting of text without the presence of a physical keyboard. More advanced features such as word correction and prediction are also available.
The Qt Project is an open collaboration effort to coordinate the development of the Qt software framework. Initially founded by Nokia in 2011, the project is now led by The Qt Company.
KDE Plasma 5 is the fifth and current generation of the graphical workspaces environment created by KDE primarily for Linux systems. KDE Plasma 5 is the successor of KDE Plasma 4 and was first released on 15 July 2014.
The KDE Gear is a set of applications and supporting libraries that are developed by the KDE community, primarily used on Linux-based operating systems but mostly multiplatform, and released on a common release schedule.
KDE neon is a Linux distribution developed by KDE based on Ubuntu long-term support (LTS) releases, bundled with a set of additional software repositories containing the latest versions of the Plasma 5 desktop environment/framework, Qt 5 toolkit and other compatible KDE software. First announced in June 2016 by Kubuntu founder Jonathan Riddell following his departure from Canonical Ltd., it has been adopted by a steadily growing number of Linux users, regularly appearing in the Top 20 on DistroWatch.com's popularity tables.
MX Linux is a Linux distribution based on Debian stable and using core antiX components, with additional software created or packaged by the MX community. The development of MX Linux is a collaborative effort between the antiX and former MEPIS communities. The MX 'name' comes from the M for MEPIS and the X from antiX – an acknowledgment of their roots. The community's stated goal is to produce "a family of operating systems that are designed to combine elegant and efficient desktops with high stability and solid performance".
