(Listas de Correo en Español)

We have three main English-language mailing lists: one strictly for announcements, one for general discussions, and one for developers.

Low-Volume Announcement-Only List

The announcement-only list has a Web archive.

Our announcement-only list is intended for people who need to track releases and important patches but don’t wish to participate in discussions. The list is moderated to avoid irrelevant posts. The volume is extremely low—only a handful of messages a year. Ideal for systems administrators!
