Gnome 3.18

[dmaglio]

Not compatible with Gnome 3.18 (Fedora 23)

Sadly same issue on Gnome 3.18.2. Extension installs fine but it cannot be activated. Warning message says 'Extension does not support shell version'

If you edit ~/.local/share/gnome-shell/extensions/temperature@xtranophilist/manifest.json you can add 3.18 to the list of supported gnome-shell versions. After that I restarted gnome (alt+f2 then type r and hit enter) and started the tweak tool and saw I could turn it on.
