-Update to SDK version 35
+Complete UI overhaul that gives DoNext a nice, modern look.
+Complete code rewrite to Kotlin and Android Jetpack, with a better architecture.
+
+Task lists are now displayed in a navigation menu
+Tasks are now ordered by priority and not cycles
+All tasks can be Done or Removed instead of only the first one
+A Recycle Bin was added
+The whole Next and cycles mechanism was removed
+The History page was removed and its features split between the regular task lists and the Recycle Bin
+The Today view is not a separate concept now, it's based on the tasks due date
+No more Settings page as it's not needed anymore (but it may come back later if required)
