-of actions.

-
-Bug reports will be closed if the issue has been inactive and the latest affected version no longer receives support. At the moment, Electron maintains its three latest major versions, with a new major version being released every 12 weeks.

-We accept issues in *any* language.
-When an issue is posted in a language besides English, it is acceptable and encouraged to post an English-translated copy as a reply. 
-Anyone may post the translated reply.
-In most cases, a quick pass through translation software is sufficient.
