Changelog v3.0.0

Changes between v2.12.1 and v3.0.0

Release date: October 16, 2015

Important notes

KNIME 3.0 is a major new release and comes with some new or slightly modified API. We did our best to retain API stability, though if you have developed custom extensions or using non-standard API (or eclipse API), minor changes to your code or a recompilation are required. We have summarized the changes on this page.

Due to changes in underlying frameworks (e.g. Eclipse and Java) some nodes produce different results than in earlier KNIME version. The result are and have been correct, however the ordering of rows, columns, or items in collections may be different. In very rare cases predictive models are slightly different because in case of ties usually the order of the data items is used as a tie-breaker.

In particular the following nodes are affected:

  • Group By
  • Naives Bayes Learner/Predictor
  • SVM Learner/Predictor
  • Extract Color
  • One to Many
  • JFreeChart Pie Chart
  • MoSS
  • Term co-occurrence counter
  • Chi-square keyword extractor
  • NGram creator
  • All tagger nodes from the textprocessing extension
  • K Nearest Neighbor
  • Feature Inserter
  • Table Indexer
  • Shortest Path
  • Partition Table
