+# Changelog for upcoming version: v2.2
+
+This update provides some new features for the design. It also contains some improvements and I have also fixed some bugs.
+
+## New features
+
+- The overview page now has the note column and is overall better organised
+- I also addded the regular header to the page
+- I have added three animations to the Borrow System
+- I have added a new icon for the frontend, which is now also used in the header and the favicon. It is a dark version of the old icon, which fits better to the overall design. I have made it with Icon Composer. The old icon is still used for the admin panel, which has a light design. (Maybe I will change the admin panel design in the future...)
+- When you go to your user card (over the user icon in the header) you have a new button "Click me". If you click it, you will get an message... _I am just saying: I have implemented the no-as-a-service code in to my Backend._
+
+## Improvements
+
+- I have the error logging for the API route wehre you can take loans improved.
+- If you try to delete a loan that has not been returned yet, you will get an 507 error code.
+
+## Fixed bugs
+
+- Fixed bug: #13
+- Fixed bug for messaging when server has an error
+- Fixed footer height
+
+---
+
+## New version numbers
+
+**Backend:** v2.2
+
+**Frontend:** v2.2
+
+**Admin panel:** v1.3.2
