• Change location providers to allow updates. GeoClue and CoreLocation now provide continuous location updates.
• Allow time-based configuration i.e. setting the redness effect based on time of day instead of based on the elevation of the sun. See the man page for more information.
• Now looks for the configuration file in ~/.config/redshift/redshift.conf (or ${XDG_CONFIG_HOME}/redshift/redshift.conf) if $XDG_CONFIG_HOME is set. The old location at ~/.config/redshift.conf is deprecated but still searched as a fall back.
• Run hooks when enabling/disabling Redshift.
• Default temperatures changed to 6500K during daytime and 4500K during night.
• With randr, allow multiple but not all CRTCs to be redshifted.
• Removes deprecated original GeoClue location provider (use GeoClue 2 instead).
• The option for enabling the short fade between color effects is now called fade instead of transition in the configuration file. The term transition caused a lot of confusion about what this option does (the old option still works but is deprecated).
• The preserve option is enabled by default for vidmode, randr, Windows (w32gdi) and macOS (quartz). The option is now controlled by the -P command line option.
• Work around issue where Windows adjustments sometimes fail.
• Install AppArmor profile.
• quartz: Fix incorrect use of display identifier.
• Various bug fixes and updated translations.

• Add option preserve for gamma adjustment methods (randr, vidmode, quartz, w32gdi) to apply redness on top of current gamma correction.
• Fix #158: Add redshift.desktop file to resolve an issue where Geoclue2 would not allow redshift to obtain the current location (Laurent Bigonville)
• Fix #263: Make sure that the child process is terminated when redshift-gtk exits.
• Fix #284: A sample configuation file has been added to the distribution tarball.
• Fix warning message in redshift-gtk that is some cases caused redshift-gtk to fail (#271) (Christian Stadelmann, Javier Cantero)
• Fix #174: Use nanosleep() for sleeping to avoid high CPU load on platforms (NetBSD, ...) with limitations in usleep() (Piotr Meyer)
• Various updates to man page and translations.

• Fix #80: Add Geoclue2 location provider.
• Add CoreLocation (OSX) location provider and Quartz (OSX) gamma
  adjustment method.
• Add hooks for user actions on period switch.
• Be less verbose when color values/period did not change.
• Add config setting to set gamma separately for day/night.
• Add support for custom transition start and end elevation (Mattias
  Andrée).
• redshift-gtk: Show errors from child process in a dialog.
• Fix #95: Add AppData file for package managers.
• Use gettimeofday if POSIX timers not available (add support for
  OSX).
• Fix #41: Do not jump to 0 % or 100 % when changing direction of
  transition (Mattias Andrée).
• redshift-gtk: Relay USR1 signal to redshift process.
• redshift-gtk: Notify desktop about startup completion.
• Fix: systemd unit files were built from the wrong source.
• Fix #90: Print N/S and E/W in the location (Mattias Andrée).
• Fix #112: redshift-gtk: Do not buffer lines from child indefinitely.
• Fix #105: Limit decimals in displayed location to two.
• Update dependencies listed in HACKING.md (emilf, Kees Hink).
• Fix: Make desktop file translatable.
• Add Travis CI build script.

• Fix: Do not distribute redshift-gtk, only redshift-gtk.in.
• Fix: Geoclue support should pull in Glib as dependency.
• geoclue: Fix segfault when error is NULL (Mattias Andrée).
• geoclue: Set DISPLAY=:0 to work around issue when outside X (Mattias Andrée).
• redshift-gtk: Fix crash when toggling state using the status icon.
• redshift-gtk: Fix line splitting logic (Maks Verver).

• Use improved color scheme provided by Ingo Thies.
• Add drm driver which will apply adjustments on linux consoles (Mattias Andrée).
• Remove deprecated GNOME clock location provider.
• Set proc title for redshift-gtk (Linux/BSD) (Philipp Hagemeister).
• Show current temperature, location and status in GUI.
• Add systemd user unit files so that redshift can be used with systemd as a session manager (Henry de Valence).
• Use checkbox to toggle Redshift in GUI (Mattias Andrée).
• Gamma correction is applied after brightness and temperature (Mattias Andrée).
• Use XDG Base Directory Specification when looking for configuration file (Mattias Andrée).
• Load config from %LOCALAPPDATA%\redshift.conf on Windows (TingPing).
• Add RPM spec for Fedora in contrib.
• redshift-gtk has been ported to Python3 and new PyGObject bindings for Python.

v1.8 (2013-10-21)

• IMPORTANT: gtk-redshift has changed name to redshift-gtk.
• Fix crash when starting geoclue provider. (Thanks to Maks Verver)
• Fix slight flicker int gamme ramp values (Sean Hildebrand)
• Add redshift-gtk option to suspend for a short time period (Jendrik Seipp).
• Add print mode (prints parameters and exits) by Vincent Breitmoser.
• Set buffering on stdout and stderr to line-buffered.
• Allow separate brightness for day and night (Olivier Fabre and Jeremy Erickson).
• Fix various crashes/bugs/typos (Benjamin Kerensa and others)
