Because Qt 5 is not improving any more, but Qt 6 is. An example would be when running under Wayland environments on linux -- it's a very broken mess on Qt 5 and will never be fixed. On Qt 6 it's only a slightly-broken mess, and will likely be non-broken within the next 12 months. There's a similar situation for apple processors, which never had full official support on Qt 5 but ARE fully supported on Qt 6. This gap is only getting wider as newer operating system updates and corresponding changes break things underneath Qt 5. There's also a limited stream of bug fixes getting ported back to Qt 5.15, vs those flowing into the supported Qt 6 releases. > That is surprising to me at this point. > Do we still believe that if one assumes "qgis with N random plugins that > claim to support qt6"? (Well, QGIS + **ANY** plugin = a less stable QGIS. 🤣 But that's a completely different point) > I expect a qt6 build is kind of like a .0 release, and we would want to > have qt6 builds widel avaialable and time for feedback before saying > it's stable. I'd say we're well past the ".0" stage of Qt 6 support. Almost all the core functionality is quite well tested at this stage, and third party clients (like Mergin and QField) switched to Qt 6 based QGIS builds earlier this year. I'm confident that by the time we hit a (potential) October 2025 milestone that we'll have a very stable Qt 6 build available.
