What's New in RapidMiner Studio 8.2.0?

Released: May 08th, 2018

The following describes the bug fixes in RapidMiner Studio 8.2.0:


  • Double-click on an unconnected operator port will connect it to a matching output port of the process.
  • The menu View -> Show Panel is now scrollable.
  • Updated visualization of tutorial's next button to go to next tutorial or back to tutorial overview when reaching the end of a tutorial or a chapter respectively.
  • Removed search button from search bar and changed result dialog to open with one-click logic.
  • Creating a RapidMiner Server repository no longer stores the credentials automatically. However, if desired you can still do so by selecting the "Remember Password" checkbox when creating the repository.
  • Panels now always have proper tooltips.
  • Improved visualization of nested Operators.
  • Added primary parameter mechanic to some Operators; double clicking an Operator now opens the editor of a primary parameter. This also works for operators that have subprocesses. In that case, pressing the Alt-key while double-clicking activates the primary parameter.
  • Quickfixes now can be directly accessed after a process run fails from the error bubble.
  • Improved performance of FP Growth and added support for additional input formats.
  • The status bar (found at the very bottom of RM Studio) now more precisely displays possible actions when editing a process.
  • Pressing the arrow keys in the process panel when no operators are selected will now select the first operator.


  • Parallel operators now produce identical results when running in parallel and when running sequentially
  • Removed several sources for redundant undo steps
  • Fixed a bug that could lead to incomplete output of Execute Program
  • Fixed and improved on generic process runtime errors
  • Fixed erratic behaviour of EMClusterer
  • Date to Nominal does no longer remove the role of the selected attribute
  • Fixed a bug where results from Data to Similarity Data could not be processed further
  • Fixed an issue that could result in the "Drag here" annotation being shown in the process all the time when using the Global Search
  • Fixed a bug that allowed operators to connect to themselves
  • Fixed Web Analytics template
