-- Diff: when comparing a file now the links says Current/FILE instead of None
+- Diff:
+  - When comparing a file now the links says Current/FILE instead of None
+  - The default was to compare the current file on storage, now is the current
+    file on memory. It includes the zone refill indicated in the preflights.
+    (See #295)
 - Now the global `dir` option also applies to the preflights, can be disabled
   using `use_dir_for_preflights`. (#292)
 - When importing globals now options that are lists or dicts are merged, not
