--------------------
* Use ``zope.container`` instead of ``zope.app.container``. (Browser code
still needs ``zope.app.container`` as it depends on view classes of this
package.)
* Encoded passwords are now stored with a prefix ({MD5}, {SHA1},
{SSHA}) indicating the used encoding schema. Old (encoded) passwords
can still be used.
* Add an SSHA password manager that is compatible with standard LDAP
passwords. As this encoding gives better security agains dictionary
attacks, users are encouraged to switch to this new password schema.
* InternalPrincipal now uses SSHA password manager by default.
