Where to download the old KNIME SDK?

I created a new node with latest SDK and it works fine in KNIME 2.7

But when I try to install this node into KNIME 2.6 it complains cannot open the NodeFactory.

So I want to find an old version SDK and recompile my code. But I cannot found a link to these files.

Where can I get these files?

Thank you.

Hi Madlee,

here http://knime.org/downloads/previous you can find all previous versions of knime.

Best, Iris

Yeah, Great! Thank you very much. :)
