We should write somewhere that for the latest version of doc, only the english version will be monitored and kept up-to-date by the maintainers. The rest looks good to me!

agreed. the English translated version now is several versions ahead of the translated. thats a problem.

for the english version, add the tip: 'only the english version will be monitored and kept up-to-date by the maintainers'

for the zh-CN version, add the same tip and mention the translator which is me.
