Main article: Qt (software)

The latest version of Qt is 6.5 released on 3 April 2023.[1]

Also still supported, for commercial users,[2] are 5.15 LTS,[3] released on 26 May 2020, and 6.2 LTS, released on 30 September 2021 – long-term support (LTS) versions are generally supported for three years,[4] with a commercial license, while 5.15 support was extended to five years, so it is supported for longer or until 26 May 2025.[3] In addition the KDE project provides unofficial support for, at least, Qt 5.15,[5] i.e. not just for commercial users.

A regular release only receives patch releases during the first 6 months,Template:Citation needed until the next feature release is out, while an LTS release receives patch releases also after the next feature release is available.

Starting with 5.15 LTS, LTS releases are available only to the commercial license holders. For open source users, such LTS releases are available as regular releases only,[6] thus 5.15 is now in the commercial-only LTS phase. Qt 5.12 LTS was the last Qt version to offer an offline installer.[7] As of August 2024, Qt 6.8 is the next LTS version. You can read more about Qt releases in Qt's documentation.

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".[56]
