iJoomla.com announced that iJoomla DigiStore is now ready for Joomla 1.5! They had to pretty much re-write the entire code, but it was worth it! And it has the new product pages feature, SEF and more.  If you've purchased it before, you get a license for 1.5's FREE! 

Also they launched iJoomla DigiStore for Joomla 1.0, version 1.3.1.

So, If you're using Joomla 1.0, then you can still get the same new features as the 1.5 version: product pages, SEF etc. They also have added security to the PayPal plugin.
