-# 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
