+# Any changes you've made.  See valid prefix list above.
+# INDENT WITH TWO SPACES.  NOT TABS.  SPACES.
+# SCREW THIS UP AND IT WON'T WORK.
+# Also, all entries are changed into a single [] after a master changelog generation. Just remove the brackets when you add new entries.
+# Please surround your changes in  double quotes ("), as certain characters otherwise screws up compiling. The quotes will not show up in the changelog.
+changes:
+  - tweak: "The groin is no longer vital."
+  - tweak: "Reworks how stance damage works slightly. Having no feet or no legs means you can no longer walk at all. Behaviour with only one foot unchanged."
+  - tweak: "Canes no longer help you when you have no legs or feet."
+  - bugfix: "Non-existant feet are no longer bloody."
