Is ES 6.0.2 compatible with Python2 or Python 2/3?

[BenzSann]

ES 6.0.2 is python 2/3 but in the Release Notes: “However, this release is not completely dual Python 2 and Python 3 compatible, as it requires the Python 2 interpreter that ships with Splunk Enterprise 8.0”.Does this mean it’s only compatible with Splunk 8.0?

Has been updated:

"Splunk Enterprise Security version 6.0.x is compatible with various versions of Splunk Enterprise 7.2.x through 8.0.x. The following flag is available in the ES 6.0.x specification files:

 python.version = {default|python|python2|python3}

However, this release is not completely dual Python 2 and Python 3 compatible. In Splunk Enterprise 8.0, it requires the Python 2 interpreter that ships with 8.0. Various configuration files are set python.version = python2 on purpose. If using Splunk Enterprise 8.0, do not set the python.version flags to python3 or run in strict python3 mode at this time."
