I just created a new low traffic mailing list that carries
announcements of interest to matplotlib users. It can include new
releases, new documentation, projects that use matplotlib, tutorials,
etc.
https://lists.sourceforge.net/mailman/listinfo/matplotlib-announce
I'll still always post announcements to this list, but if you just
want the announcements w/o the extra traffic in your inbox from the
users list, you may prefer to only subscribe to the announce list.
