"... better support for Python 3". Why does VB need to better support a specific executable, namely python 3? Anyone have more technical details on this?
OK, Python for using their VM's API. Yes, that rings a bell. However, from the notes it seemed like something they modified in the VM to better support python with the guest OS ... did not make sense until. Thanks!
VirtualBox supports scripting using python; for that, it provides a python module. Just like any other python library, it needs to specifically support py3 syntax, or errors may happen.
