In last newsletter issue, the heading has been posted in English instead of its translation, whereas that has been supported since February.
Was there a bug or a misconfig?

Titles translations are supported only when you use MassMassage (MM) locally. Our newsletter is located at Mediawiki.org so if I use MM locally to distribute it, titles would be supported. However, to deliver a message at all wikis, I have to use MM at Meta.
So, I have to move everything at Meta, which was not yet done because it was not a real priority. But it might change.
