 ## Most recent changelog
 
-### January 2022
+### March 2022
 
 #### New
 
-##### Media
+##### Framework
 
-* Added the reference media type (similar to collections) which allows to create references to existing media. This is ideal for showing the same media file in different places while making sure that deleting or changing the reference doesn't effect the actual media file.
-* Create collection directories recursively (similar to `mkdir` with a recursion flag set to true)
+* Started to create C++ framework
+
+##### Billing
+
+* Allow to upload invoices as PDFs for invoice recognition
+  * Invoice pre-processing 75% completed, can be used as is but improvements are recommended
+  * Invoice layout recognition and parsing outstanding as well as manual layout definition
+
+##### Frontend
+
+* Created a tool which pre-processes invoice images
+
+#### Bug fixes
+
+*
 
 #### Other
 
 ##### Installer
 
-* Added command line to developer documentation for generating cachegrind output during installation
-* The demo setup script now uses the correct row counts instead of estimations
-* Added API call counter to demo installer script
+*
