+As always, don't forget to backup your world before updating!
+Requires CyclopsCore version 1.0.6 or higher.
+
+Additions:
+* Add config option to hash NBT tags in filenames
+  This resolves OS problems with long filenames.
+  If enabled, NBT tag contents are serialized to
+  an auxiliary txt file with the same base name.
+  Closes #5
+
+Changes:
+* Don't make export stop the export process, Closes #4
