Nova Shell returns the old classic look of the Gnome 3. I tested this version on Arch Linux GNOME 3.26 and it works well without causing any problems. So, this version is compatible with GNOME 3.14 or later. Based on the Nova Shell GNOME Shell theme, but with fixed bugs and other improvements. Under this link you can find the original version of the Nova Shell that was not fixed by me:
