Roundcube upgrade problem

[Jane1]

I tried to upgrade to the latest version but it did not finish properly.
 I received this error
 
 Your configuration files are now up-to-date!

Thanks for the reply.
By what MySQL commands shall I issue from console to update my database schema?
Or is there a better way how to update the database schema?
 Thanks for help.( I am a newbie with roundcube)

I solved the problem
I opened
/home/roundcube/SQL/mysql.update.sql and executed
ALTER TABLE `contacts` ADD `words` TEXT NULL AFTER `vcard`;
ALTER TABLE `contacts` CHANGE `vcard` `vcard` LONGTEXT /*!40101 CHARACTER SET utf8 */ NULL DEFAULT NULL;
ALTER TABLE `contactgroupmembers` ADD INDEX `contactgroupmembers_contact_index` (`contact_id`);

TRUNCATE TABLE `messages`;
TRUNCATE TABLE `cache`;

Now it seems to work GREAT!
