1 Bug: Database creation on MySql
============================
Database table "config" misses Column "ack_enable" and "ack_expire". Created them with "alter table config add ack_enable integer Default 0 NOT NULL;"

2 Bug: Database upgrade from 1.4.2. -> 1.5
==================================
Same Problem as above, upgrade/patch.sql is the version 1.4 one.

3 Bug: Importing data from *.xls-File
============================
After exporting hosts, templates and triggers from 1.4.2 to zabbix_export.xls, importing to 1.5 gives following errors:

trigger creation:
----------------------

1. Missing argument 7 for add_trigger(), called in /export/home/zabbix/software/zabbix-1.5/frontends/php/include/import.inc.php on line 476 and defined[/export/home/zabbix/software/zabbix-1.5/frontends/php/include/triggers.inc.php:677]
2. Undefined variable: url[/export/home/zabbix/software/zabbix-1.5/frontends/php/include/triggers.inc.php:687]
3. Error in query [insert into triggers (triggerid,description,type,priority,status,comments,url,value,error,templateid) values (35,'Low free disk space on {HOSTNAME}

   volume /',4,0,,'','',2,'Trigger just added. No status update so far.',0)] [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''','',2,'Trigger just added. No status update so far.',0)' at li]

host creation:
--------------------

1. Host [<hostname>] skipped - Access deny.

item creation:
--------------------

1. Item [Ping] skipped - missed host
2. Item [Ping RRT] skipped - missed host
   ---> OK this is normal, as the host was not created

I noticed, that templates kann only be updated, since the "Missing" pull-down only has Skip as an option.
