Not sure I can, without accompanying explanations: https://www.qt.io/blog/qt-offering-changes-2020 Qt5 upstream (Qt Company) OSS support ended on 2020-12-08. Since then, bugs are only fixed if reproduced in Qt6 first, then backported. Since then, public availability of commercial 5.15 LTS releases is delayed by 1 year, including repository access for cherry-picking - this is important, see below, and affects Gentoo first and foremost. The last official LTS release will be this April/May: https://www.qt.io/blog/qt-5.15-extended-support-for-subscription-license-holders https://wiki.qt.io/Qt_5.15_Release#Release_Plan Public availability of this release will be *1 year later*. Some may think now, fine, updates (3 in total) until 2026! However, if a dependency/toolchain upgrade down the stack breaks Qt5 between now and March/April, to be then fixed in their final release, you will be waiting until April/May 2026 for that to be available. If it breaks later than April 2025, you will be waiting forever. In either case, you rely on downstream volunteer patchwork. KDE Qt5PatchCollection ultimately relies on Qt company's upstream commits as well, so don't expect any original work from there to get things fixed. In any case, there is no clear EOL date for these patches, but they *will* be drying up as there is no main KDE consumer left, I certainly know that my contributions come to an end. https://community.kde.org/ Qt5PatchCollection#For_how_long_will_this_be_maintained?
