There are a few important changes in the database configuration, which I wanted to quickly point out:
1. ‘connect’ key is gone.
For example, if you had ‘connect’ => ‘mysql_connect’ you will need to replace it with ‘driver’=>’mysql’
2. New key: ‘persistent’=>false
This one is very important and you definitely want to add it to your configuration file.
It had caused me some pain, before I noticed this ticket:
