First of all, congratulations to the Joomla project for launching the latest version of their open source content management system Joomla version 1.7 today.
We at StackIdeas are ready for this and rest assured our components EasyBlog and EasyDiscuss are all set for Joomla 1.7, natively.
The folks at the Joomla project were thoughtful enough to make the transition process smooth with a one-click upgrade. So, if you haven't got the latest version, you download it HERE.
