Join the Chebfun mailing list to get announcements of new developments. We aim for about one message a month; you will not be spammed.
The mailing list is hosted as a Google group named chebfun-announce. If you have a Google account, click here to join. Note that you may need to login to your Google account first for this link to work.
If you don't have a Google account, you can still join, though it requires a little more effort. As of December 2015, you can do it like this:
Send a blank e-mail to firstname.lastname@example.org.
Respond to the confirmation e-mail you then receive with a further blank message.
Thanks from the Chebfun team, and remember that you can always contact us with questions or suggestions at email@example.com.
