R devel - Dec 2019 - Assumption of Gaussian innovations in function stats::arima

Hi, if I read the help to function stats::arima carefully enough, I have not
found any mentioning of the assumption that
the innovations e[t] (notation from the help file) be Gaussian. I think this
assumption should be included. In
particular, the returned information on the log likelihood would be wrong
otherwise.
