None, ever. I never subscribe to newsletters. I hate spam. I subscribed to newsletters in the past to only regret my decision because it was used to funnel spam/ads and annoy me with meaningless updates.

I would appreciate a common spec where packages could ping new releases, something like rss I could then subscribe to and get new release notifications with a changelog.

But mail is something where I don't want spam. Email is for important messages and invoices. I'm trying to keep that space clean.
