Dear KNIME User,
We have just released a new version of KNIME which fixes a few minor, non-critical bugs. A detailed list of what has been fixed can be found here.
KNIME Desktop 2.3.1 can be downloaded from the download page or you can upgrade your existing KNIME v2.3.0 installation by using the built-in update functionality available in the "File" menu (or "Help" in the developer version).
The KNIME team.
