Joomla just released the maintenance version 1.5.19 today. According to Joomla, this is a low-medium security release. At least there is one low security and three medium security have been fixed. Although it is not high priority, we urge to always upgrade your Joomla to latest version for your own safety.

If you want to upgrade your Joomla, you may always want to see first in Joomla forum if there is any problem caused by the upgrade. You may want to wait for a while until it is sure that there is no critical problem arise after the update. And as always we recommend to always backup first before doing any upgrade.

We have tested to all our templates that the upgrade to Joomla 1.5.19 has no effect to our templates.
