+- Important bugfixes for PTME. See `q7s-package` CHANGELOG.

 ## Changed
 
 - Persistent TM store dumps are now performed in chronological order
 
-# [v4.1.0]
+# [v5.0.0] 2023-06-26
+
+v3.3.1 and all following version will now be moved to v5.0.0 with the additional changes listed
+here. This was done because the firmware update (v4.0.0) is not working right now and it is not
+known when and how it will be fixed. Because of that, all updates to make the SW work with the new
+firmware, which are limited to a few files will be moved to a dev branch so regular development
+compatible to the old firmware can continue.
+
+TLDR: This version is compatible to the old firmware and some changes which only work with the new
+firmware have been reverted.
