* Use QT 6.10.0
* Change invalidateFilter (deprecated) to beginFilterChange/endFilterChange
* Remove warning of presenceStatusItem
* Add changelog with this modification for 6.1.0
* Do not use anymore variables to build docker images. Qt versions are now hardcoded in images to allow multiple opensource Qt versions.
Add QT proprietary 5.15.14, 5.15.19, 6.8.1, 6.8.3 in Dockerfile.
Modified CI and dockerfile to use qtchooser, to keep the same behaviour without having to rely on a specific entrypoint.
Split opensource versions from proprietary versions by using a different directory.
