During the last days I had the time to test the CMIS Input plugin for Pentaho Data Integration on the latest version 126.96.36.199-353. The CMIS Input plugin version is the latest: version 1.3. The results of the tests are that the latest version is confirmed as compliant to the brand new Pentaho release.
Below you can see the screenshot of the resulting transformation (the simplest you can develop) as detailed in the documentation. Of course the documentation is related to a previous version of Pentaho Data Integration and below the same transformation (developed exactly in the same way) with Pentaho Data Integration version 188.8.131.52-353.
For further requests about the plugin, please use the GitHub issue list.
