Joomla Version Support
We supported our extensions in Joomla 1.5, 1.6 and 1.7 well past the official end of life of those versions. But Joomla continues to evolve rapidly, and it became impossible to prepare our code for future versions while maintaining support for obsolete versions. Each new release of Joomla removes older functions, replacing them with new ways of doing things.
In the latest releases of our products, we are removing the code that supported Joomla 1.5, 1.6 and 1.7, improving our support of Joomla 3.x, and preparing for future versions of Joomla by migrating deprecated functions. We will continue to make the legacy versions of our products available for download until the end of 2014, but these old versions will no longer be developed or receive bug fixes.
We will continue to support Joomla 2.5 until at least its official end of life - December 31st, 2014.
There's a handy table of Joomla versions here
We will always do our best to help you if you have a problem with one of our extensions, whatever your environment, but please be aware that if you encounter a complex problem, we may well ask you to upgrade to the latest version of our product, which may not support older versions of Joomla.
If you are using an obsolete version of Joomla, you should think about upgrading.
