Qt offering changes 2020

The Qt blog has announced somechanges in how the Qt toolkit is offered to consumers. Notably,installation of Qt binaries will require a Qt Account andlong-term-supported (LTS) releases and the offline installer will becomeavailable to commercial licensees only. "From February onward, everyone, including open-source Qt users, will require valid Qt accounts to download Qt binary packages. We changed this because we think that a Qt account lets you make the best use of our services and contribute to Qt as an open-source user.We want open-source users to help improve Qt in one form or another, be that through bug reports, forums, code reviews, or similar. These are currently only accessible from a Qt account, which is why having one will become mandatory."
