The changelog.txt file should have a list of any SQL changes you need to apply to your database. The errors you are getting there relate to Zone instancing. I think these are all the SQL changes relating to that:
Code:
INSERT INTO variables VALUES ('curInstFlagNum', 2000, 'Determines what instance flag will be handed out next', '2008-09-05 04:46:47');
ALTER TABLE `zone` ADD column `insttype` tinyint (1) zerofill unsigned NOT NULL default '0';
ALTER table character_ ADD column `instZflagNum` int(10) unsigned NOT NULL default '0';
ALTER table character_ ADD column `instZOrgID` int(11) NOT NULL default '0';
INSERT INTO variables VALUES ('dfltInstZflag',1000, 'Used to determine if a zone is instanced, must be 1000 or greater', '2008-09-05 04:46:47');
