 ### Changed
 
 - Multiple command options can be combined
+- (!) History uses `XDG_STATE_HOME` directory by default:
+  This constitutes a break in behavior if you relied a lot on your pick history in the default
+  location. To retain your old history file, simply move it from the old cache directory
+  (`~/.cache/bemoji-history.txt` by default) to the new one (`~/.local/state/bemoji-history.txt`

 You can overwrite the directories bemoji uses for its emoji lists and history files with the following two environment variables:
 
 ```
 BEMOJI_DB_LOCATION=/path/to/my/emoji/directory
-BEMOJI_CACHE_LOCATION=/path/to/my/cache/directory
