+- due to [`3cf9be8`](https://github.com/JakeStanger/ironbar/commit/3cf9be89fd74face31806165f66b68052b093bab) - global icon theme setting *(commit by [@JakeStanger](https://github.com/JakeStanger))*:
+
+  This removes the `icon_theme` option from `launcher` and `focused`. You will need to set this at the top of your config instead.
+
+- due to [`90f57d6`](https://github.com/JakeStanger/ironbar/commit/90f57d61b94c50c98a6f55de18c6edf3d18aa3fa) - remove irrelevant `icon` format token *(commit by [@JakeStanger](https://github.com/JakeStanger))*:
+
+  (Missed from #96141d4) The `{icon}` token has been removed from the `music` module due to incompatibility with the new image/icon support. The icon now always displays as a separate widget before the label and should be removed from your formatting string.
