+## [0.1.2] - 2024-07-17
+* Fix: Allow negative values in --location and --scheme arguments
+* Fix: Apply gamma ramps without checking if it's changed in daemon mode
+  to restore the desired ramps faster when an external program changes them. See
+  'Why does the redness effect occasionally switch off for a few seconds?' in
+  docs/redshift-readme.md
+* Fix: Minor changes to the set command
+  * Remove the hard requirement of providing at least one of the temperature,
+    gamma or brightness cli arguments
+  * Always use the default values of temperature, gamma and brightness when they
+    don't exist. Don't use the values provided by the config file
+* Feat: Add systemd service
