Warning! Version 2.22 uses the standardized (updated) method of calculation
of the signature of integrity CRC-64, therefore for work with archives of
earlier versions (before 1.60) it is required to establish a tick of
"Options" => "Fast extraction" (a mode of the miss of check CRC-64).

Version 2.22 is capable to protect data from not authorized access using
algorithm AES-256 through encryption filter which can be activated through
item of the menu of "Options" => "Encryption filter".
