 [Full Changelog][changelog]
 
-✨ This release adds support for Hass.io Ingress 🎉 
-
-Besides Ingress, this release adds major upgrades about every single thing inside this add-on ⬆️ 
-
-### 🚨Breaking change
-
-The addition of Ingress makes this add-on not accessible directly. If you have added Grocy via an iframe panel, this release will break that. However, you can simply toggle the "Show in sidebar" switch now 🎉 
-
-You can enable direct access again by going into the add-on configuration. A section is visible: "Network". Enter port `9192` (or anything else if you want) in the `disabled` field. Hit the "SAVE" followed by the "RESTART" button to make your iframe and others work as before.
+This is a maintenance release.
