Was looking at why redshift (https://github.com/jonls/redshift/releases) wasn't supporting a day/night adjustment and it turns out it's still version 1.7.2 in unstable which is about 3 years old. Version 1.8 is about 7 months old but isn't even in experimental.
[edit] sent an email to the maintainer, but in the meantime, you can get debs for 1.8.0 from Ubuntu:
http://packages.ubuntu.com/trusty/amd64/redshift/download (http://packages.ubuntu.com/trusty/amd64/redshift/download)
http://packages.ubuntu.com/trusty/all/redshift-gtk/download (http://packages.ubuntu.com/trusty/all/redshift-gtk/download)
The basic redshift requires geoclue geoclue-hostip and libxcb-randr0
redshift-gtk also needs python-appindicator libappindicator1 libdbusmenu-glib4 libdbusmenu-gtk4 libindicator7
