I am developing a new KNIME node. As I have been building newer versions, it created several versions of plugins so far. It works great when I test it by launching KNIME platform from the Eclipse SDK. But when I try to add the new node to a standard KNIME installation, the local update site (which actually contains the latest build) does not show the most recent version. And also, it shows me an older version although I checked the option to show only the latest version. Is there a way to clear the previous version from the local update site and start afresh?
