Dear KNIME User,
We have just released KNIME 2.7.4 which fixes few non-critical problems. For full details see the changelog http://tech.knime.org/changelog-v274
KNIME Desktop 2.7.4 can be downloaded from the download page (http://www.knime.org/download) or you can upgrade your existing KNIME 2.7 installation by using the built-in update functionality available in the "File" menu (or "Help" in the developer version).
The KNIME team.
