Hi everyone, Since we are talking about the future of Qt these days, I would like to know The Qt Company free software policy with Qt.
Today, most of Qt modules are released under 3 free software licenses: LGPLv3, GPLv2 and GPLv3. Some modules are released only under GPLv3. If my memory is good, these GPLv3-only modules are the ones which used to be commercial-only modules (like Qt Charts). However, it seems to me that most, if not all (except Qt 3D), new Qt modules are now being released only under GPLv3: - Network Auth - WebGL - WASM - Http Server - Lottie - Quick 3D - MQTT I understand that The Qt Company is only obligated to release new modules under GPLv3 (because of the KDE agreement). I understand also that The Qt Company business model is selling Qt licenses and has no direct financial interests in releasing Qt under any other license. So I can understand that some modules, in particular those valuable for wealthy industrial companies, are only released under GPLv3. However, for some modules like HttpServer, it seems to be an odd choice. There are plenty alternatives available under LGPL or more permissive licenses, so I do not see what would be the loss of releasing it under LGPLv3. Also the fact that those modules are GPLv3 only is a problem when developing with other components that are GPLv2 only (and not GPLv2+). So I would like that someone could officially confirm if all new modules will be released under GPLv3 only. Or if it is something that is decided on a per module basis. I believe that Qt users and contributors deserve to know what it The Qt Company view on this. Using an LGPLv3 framework is not the same thing as using a GPLv3 framework where some historical parts are available under LGPLv3 and all new features will be GPLv3 only. BR, Benjamin
