There has been some confusion as to the different versions of the legacy component on the download page. We provide two different versions for specific needs.
1. The original component as delivered to customers, but with no encryption. This version does not have any bugfixes but can be used to migrate modifications.
2. The bugfixed version of the original component. This version requires the legacy plugin but has bugfixes and no longer requires "call-back" to ZCS to work. It will install on Joomla 1.0.x.
Neither of the versions is supported by our customer support team. We will also not be releasing any updates or patches for these versions. You run them at your own risk. In order to develop a component for both Joomla 1.0.x and 1.5.x a lot of compromises have to be made. We don't recommend running either of these on a production site.
If you have any questions related to either of these components, contact customer support through email or live chat.
For those of you that have asked, our new "key-free" search form uses the Google Maps API v3. Google decided to drop support for IE6 with version 3 so our new search form does not work with IE6. However, we still include the older form which uses Google Maps API v2 (and a key) if you need to support IE6. The non-javascript enabled search form should support almost any browser.
Eventually we will drop support for IE6 altogether. So encourage your customers to upgrade their browsers.
