/*

# Updates

Before a major version update, make a copy of this directory. (We like to
keep the old version around for a short time after major updates.) Add a
top-level attribute to `top-level/all-packages.nix`.

1. Update the URL in `pkgs/development/libraries/qt-5/$VERSION/fetch.sh`.
2. From the top of the Nixpkgs tree, run
   `./maintainers/scripts/fetch-kde-qt.sh > pkgs/development/libraries/qt-5/$VERSION/srcs.nix`.
3. Check that the new packages build correctly.
4. Commit the changes and open a pull request.
