Knime Long Term Support

Hi everyone,

Currently I’m developing Knime extensions for one of my client, but I’m wondering if there is a long term support on Knime, or what are the oldest supported version (in order to target the right environment, as the current environment is 4.10 for the server and 4.1 for the executor).

I didn’t find any version sheet on the website nor using google or your favorite search engine.

Can you tell me if there is a link available for that ?

Thanks !
