Hi Neil,

Just want to ask a silly question: lava(merged lava-server and lava-dispatcher) is updated to Python3 or not? If not, does development team has a plan to update it to Python3?

Thanks and Regards,

Yifan

With all due respect, Sir, I would not agree/would disagree to by
your/Linaro's currently presented architecture.

Sorry, but this was only a notification of a decision already taken and implemented by the development team. The change itself was not and is not up for discussion on this list.
