Missing row ui_limit in table ds_fields.

While using the latest version of DS 2.x-dev (05/19/2012) I tried to create a DS code field and got this error message. Checking the repo on d.o and the .install file I don't finde the missing row as well.

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'ui_limit' in 'field list': INSERT INTO {ds_fields} (field, label, field_type, entities, ui_limit, properties) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5); Array ( [:db_insert_placeholder_0] => qwertz [:db_insert_placeholder_1] => qwertz [:db_insert_placeholder_2] => 5 [:db_insert_placeholder_3] => a:1:{s:4:"node";s:4:"node";} [:db_insert_placeholder_4] => s:17:"gm_persons|teaser"; [:db_insert_placeholder_5] => a:2:{s:4:"code";a:2:{s:5:"value";s:13:"return 'bla';";s:6:"format";s:7:"ds_code";}s:9:"use_token";i:0;} ) in drupal_write_record()
