We have just released version 2.1 of KNIME, the most user-friendly and
comprehensive open-source data integration, processing, analysis, and
exploration platform. KNIME 2.1 is available for download at
and is, starting with this release, covered by GPLv3 (see license for details).
If you are new to KNIME, you can find a few short movies showing KNIME in action at

This new version includes - among many improvements under the hood - several exciting additions:
- Time series support: KNIME 2.1 introduces a set of nodes for handling date and time values within KNIME workflows.
- Web services: a new node is now available on KNIME labs that allows users to feed data sets to arbitrary web services. This expands the use of KNIME far beyond the built-in functionality and makes a vast amount of additional online functionality accessible from your KNIME workflows.
- Image and text processing modules: in addition to the already published text processing nodes, now a large collection of nodes to process images can also be downloaded from KNIME Labs (see labs.knime.org)
- PMML support: after offering beta functionality in version 2.0, KNIME now offers full PMML support (both as producer and consumer) for PMML.
- Asynchronous and scalable data handling: the KNIME data caching mechanism, which allows data sets limited only by available external storage space to be processed, is now handling data I/O asynchronously, hence further accelerating KNIME data handling.
- R integration: R nodes in KNIME can now also be used to produce and consume predictive models, making it even easier to include existing IP in the form of R-scripts when upgrading your business process to KNIME.
- Database connectivity: the universal database connectors and "in DB operation" KNIME nodes also support the new date and time types.
- Expanding OS Support: the vintage Linux (32/64 bit) and Windows (32 bit) versions are now complemented by a Windows 64 bit version and an experimental build for Mac OSX.
- Some additional enhancements are:
- Undo/redo functionality for the workflow editor
- Various new processing and analysis nodes, e.g. a new set of PCA nodes
- Weka Model Reader and Writer nodes
- LibSVM integration
- Workflow Directories
