Version 4.3.0 for KNIME 4.6 / 4.7

INTERNAL

• update to Java17
• replace xstream library with a new version due to failing dependency check
• fix class loading issues for RGG

SCRIPTING

• R nodes will not end up with failed transfer for tables with a single column of unsupported data type. Instead an empty table will be transfered
• #109: KNIME Analytics Platform prompts for proxy user and password on startup

CHANGES BEFORE v4.3.0

• Python nodes version 2 with a lot of changes anf features

Version 4.2.0 for KNIME 4.5

• Upgrade to Java 11 and Eclipse 2021-03
• Update to poi 3.17

Version 3.3.0 for KNIME 3.7

ENHANCEMENTS / FEATURES

• Template files will be cached locally to allow offline usage

ISSUES

• Nodes using R will use Rserve library 1.8-6 to avoid communication problems with R 3.5+

Version 3.1.1 for KNIME 3.5/3.6

ISSUES

• externalize libraries to avoid conflicts
• #95: Matlab Snippet: Output argument not assigned during call to ...
• #91: Cannot import data to matlab
• #84: Adding templates in the preferences fails silently when rgg syntax error
• #82: update to java 8
• #81: Support the Matlab type table in snippets
• #63: Matlab jmi ClassLoader problem
• #64: Groovy scripts wont compile due to broken import statements

Version 3.1.0 for KNIME 3.1

INTERNAL

• R integration restructured and transfer from/to R improved

ENHANCEMENTS / FEATURES

R nodes now can

• transfer data in chunks (for big tables)
• transfer KNIME color/size/shape model
• transfer rowIDs
• directly 'open external'
• transfer domain values
• transfer flow variables
• handles empty tables correctly
• supports double, int, long, boolean and string and ommits other column types

ISSUES

• fixes #67: Rserve process hangs under Windows after R-Plot node failure
• fixes #35: RGG line break bug after Edit Template
• fix: OpenInPython does not work under Windows (no window opens after execution)
• Use new Rserve version 1.7 #42
• Include Open in R funcionality into R plot node and R snippet node #4
• Generic plot node should get image outport #66
• Stop support of old R variable names #54
• transfer R workspace with generic nodes #47
• Support domain values from KNIME as levels in R #43
• row ids should be used as row names in R-data.frame #9

NEW NODES

• Generic R nodes (new versions)
  R port now acts as workspace transfer

Version 2.0.4 for KNIME 2.11

ISSUES

Scripting

• fixes #59: template configuration dialog has too much empty space

Matlab

• fixes NullPointer-Exception when executing a matlab node.
• Simplifying the Matlab controller (only to work on the local machine)

R

• undo row names support as pushing row names like this suffers from an RServe-bug
• closes issue #42: Use new Rserve version 1.7
• changed R icons and fixed node types in xml and added icon for splash screen

Version 2.0.4 for KNIME 2.10

Version 2.0.3 for KNIME 2.10

New features

The scripting integration needs a MATLAB installed on the local machine. But no more middle-ware (server) is needed. The MATLAB nodes can control MATLAB remotely and start an instance if needed.

Issues

#27 The MATLAB type can be configured in the preference dialog
#26 Multiple nodes can execute simultaneously on one or more MATLAB instances

Version 2.0.2 for KNIME 2.11

ISSUES

scripting

• closes #49: remove output tab from snippet node (main changes in AbstractTableScriptingNodeModel)

Python

• part of #55: integer columns are transfered as float to allow missing values
• some changes for better NaN/missing value handling with python snippet node (not yet finished)
• fixes #56: Python plot fails under windows

R

• fixes #53: check if plot was generated and give error message
• fixes #50: fix R port of generic nodes, return structure of objects transfered via RPort
• fixes #7: RPlot - Null Pointer Exception if plot node contains a nonvalid output path
• closes #10: Plot Overwrite - Warning instead of Error
• fixes #5: Generic OpenInR - pushes rOut instead of kIn
• R-scripting - improve error message if plot file path is invalid (was: reporting Null-Pointer exception)
• enables R-nodes to push row-names for table inputs
