+# 0.13.0 - new callback, and preserving script state on reloads
+
+## `on_script_reloaded`
+Scripts can now subscribe to `on_script_reloaded` and `on_script_unloaded` in order to preserve state between reloads:
+
+```lua
+function on_script_unloaded()
+    print("Goodbye world")
+    return "house key"
+end
+
+function on_script_reloaded(value)
+    if value then
+        print("I'm back. Thanks for the keys!")
+    else
+end
+```
+
+`on_script_unloaded` will be called every time a script is about to be unloaded, giving it the opportunity to return an arbitrary `ScriptValue`, this value will then be passed in to the `on_script_reloaded` 
+callback which can be used to re-initialize the script.
+
+`on_script_reloaded` will be called after `on_script_loaded`. 
+
+## Better responses
+
+script callback response events now contain the entity which triggered the response on them.
