Release Notes: This is an important security update. Strong encryption is now used for passwords. Anyone who cares about security is advised to update to this version. Existing password files for Windows users and Linux users that are not using HAVE_CRYPT are automatically converted. Those installations which used HAVE_CRYPT in the past under Linux have to ask their users to re-enter their password (via the "Forgot password" link) after upgrading to this version.
