Qt6 status in conda-forge
Qt6 has quietly become a first-class citizen in conda-forge. The recent addition of the Qt Designer Python plugin (libpyqt6.so) to the pyqt6 package closed one of the last gaps in the PyQt6 story, but it is a small piece of a much larger, multi-year community effort. This post takes the opportunity to lay out what the whole Qt6 ecosystem now looks like on conda-forge.
The migration spans more than three years. It started with the first attempts at a 6.x build in qt-main-feedstock#44 (2022), gathered urgency once Qt 5.15 reached end-of-life in May 2025, and culminated in the "flip" that made Qt6 the default — the qt6 branch was merged into main in August 2025 (qt-main-feedstock#350). PyQt6 followed in February 2026 (pyqt-feedstock#162), and qt6-webengine landed in May 2026 (qt-webengine-feedstock#90), removing the last major blocker tracked in qt-main-feedstock#349.
