Although it looks great at GitHub, I really dislike what copying the page there makes the actual announcement look like. It doesn’t look too bad below, except that the headings look odd, but when it goes to the announcement list it looks terrible. http://mail-archives.us.apache.org/mod_mbox/www-announce/201708.mbox/%3ccd8b8bef-882e-fb69-6e89-d72428416...@apache.org%3E <http://mail-archives.us.apache.org/mod_mbox/www-announce/201708.mbox/%3ccd8b8bef-882e-fb69-6e89-d72428416...@apache.org%3E>.
