@ -15,6 +15,8 @@ Version 1.13.11+dev:
* [set_menu_item] no longer fires repeatedly if the player holds the
hotkey (bug #1711). If you were relying on repeated firing, add
repeat_on_hold=yes to [default_hotkey].
* [set_variable] now supports prefix and suffix operations for
string concatenation.
* Miscellaneous and bug fixes:
* Fixed standing animation toggle not taking immediate effect (bug
#1653).
