WP 1.3 alpha 3 error and questions.

I’ve just installed WP 1.3 alpha 3 (2004-09-07) on PHP 5.0.0, everything seems to work except the change password feature. I get this error:
Database error: [Unknown column 'user_description' in 'field list']
UPDATE wp_users SET user_firstname='', user_pass=MD5('mypassword'), user_lastname='', user_nickname='Administrator', user_icq='', user_email='my@email.com', user_url='http://', user_aim='', user_msn='', user_yim='', user_idmode='nickname', user_description = '', user_nicename = 'administrator' WHERE ID = 1
ERROR: couldn't update your profile...
I haven’t modified the DB so I can’t understand why this happens. The login screen appears too many times also (while moving in the admin area) so I’ve to login several times a session.
Anyway, I have a few question about WP1.3 alpha 3:
-Would WP1.2 translations and plugins work with WP1.3a3?
-where has ‘posts paged’ option gone? I can’t find it
-Does a changelog exist for WP1.3a3?
Thanks.
