 Incompatibilities
 ~~~~~~~~~~~~~~~~~
 
+Versions 0.5 and 0.6
+^^^^^^^^^^^^^^^^^^^^^
+.The format of `rsync_options` changed:
+- Before 0.6 it was whitespace delimeted
+- As of 0.6 it is newline seperated (so you can pass whitespaces to `rsync`)
+
+You can update your configuration using `tools/config-pre-0.6-to-0.6.sub.sh`.
+
+.The name of the backup directories changed:
+- Before 0.6: "date +%Y-%m-%d-%H%M"
+- As of 0.6:  "date +%Y%m%d-%H%M" (better readable, date is closer together)
+
+For the second change there is no updated needed, as XXXX- is always before
+XXXXX (- comes before digit).
