+==== IMPORTANT Encrypted Volume data may be unreadable ====
+- If you have been using the data encryption feature of 1.39.x, please
+ be aware that certain combinations of encryption and other options
+ with version 1.39.0 through 1.39.26 created Volume data that cannot
+ be restored. We strongly recommend that anyone using encryption
+ carefully review his/her backups and at a minium do a Full backup
+ with 1.39.28 of all encrypted data. Robert Nelson has identified
+ and fixed it as follows:
+ As of 1.39.27:
+ No filters = Works fine
+ Sparse = Works fine
+ Compression = Works fine
+ Encryption = Works fine
+ Sparse + Compression = Works fine
+
+ Sparse + Encryption = Restore broken
+ Sparse + Compression + Encryption = Restore broken
+ Compression + Encryption = Restore broken
+
+ As of 1.39.28:
+ All combinations work fine.
