+v3.5.98
+- Changed to automatically download and install dtc if all of the following 4 conditions are met:
+    1. dtc is not already installed.
+    2. /bin/dtc or dtc are not in the same folder as the script.
+    3. The script needs dtc.
+    4. The script is running from task scheduler.
+- Bug fix for "Enable write_mostly on slow internal drives so DSM runs from the fast internal drive(s)." Issue #340
+- Improved output to make it clear which drive(s) have most_writely set.
+
 v3.5.97
 - Changed silently skip empty .db.new files with showing an error. Issue #175
 - Changed to warn if db file is 0 bytes.
