There have been some delays in the program re. delivery of the new Python 3 node.
The roadmap currently has the Python 3 node included as a 'stretch' item in the Data360 Analyze 3.12 LTS release. Note that a stretch item is not committed to the release so there is still a possibility that it may be bumped to a later release.
The Data360 Analyze 3.12 LTS release is targeted to be available Q4 2022.
