Hi,
We don't want to spam people with emails, that's why we send newsletters once or twice per month.
When there is a major update we put it most of the time in the newsletter, however this month we have other things to announce as well, so we are waiting a bit more for the December newsletter.
I would suggest you to follow us on Facebook or Twitter is you want to make sure to be up-to-date with all of our announcements, I think it's the best way.
Cheers,
Nicolas
