Released: Mar 24th, 2022

RapidMiner Studio 9.10.2 - 9.10.5 have been skipped and were not released.

The following describes the bug fixes in RapidMiner Studio 9.10.6:


  • Fixed a memory & file leak when using large numbers of repeated JDBC connections
  • Visualizations: Added options to customize Wordcloud word orientations
  • Visualizations: Added Jamaica to the map collection
  • Updated postgres JDBC driver to version 42.3.2
  • Added skip inaccessible parameter for Loop Files to skip inaccessible files/directories, instead of a silent failure. If unchecked, the operator does not loop at all and will throw a proper error.
  • Stopping Loop Files is now always possible in a timely manner, even if you selected a directory with millions of files.
  • Updated H2 DB library due to security advisory
  • Added new parameter fitting error handling to the ARIMA Trainer operator.
  • In case of a fitting error during training, either a proper error is thrown or a fallback Default Forecast Model is provided.

  • Fixed an issue that could sometimes cause Execute Process operators within parallel loops or similar setups to fail with a error messages like "Cannot connect to the RapidMiner AI Hub repository '_LOCAL'" when running on an AI Hub legacy repository
