The Joomla Dev Team has just released Joomla 2.5. Upgrading from Joomla 1.7.x to Joomla 2.5.x will be very easy. Most users can use the automatic update or install the update archive using the Extension Manager: Install option.
If you are using Joomla 1.5 then you will still be required to migrate your site using the jUpgrade component.
Joomla 2.5 is the direct upgrade for Joomla 1.7. Joomla 1.7 will be supported for critical security issues only for a period of one month after the release of Joomla 2.5. After that time, only Joomla 1.5 and Joomla 2.5 will be supported by the Joomla project. Note that Joomla version 2.5 is a long-term-support (LTS) release and will be supported for at least 18 months.
API Key: You do not need to obtain your own API Key from Contstant Contact. This plugin uses the JoomLadds API Key.
This tutorial will help you install this plugin. Based on version 3.1.8.
See how this plugin is used.
