Updated Roadmap for Dovecot?

[Tanstaafl]

Hello,

Just wanted to go take a peek at the latest Roadmap for dovecot, and
note that the current wiki page is flagged as obsolete:

https://wiki.dovecot.org/Roadmap

Is there an updated version somewhere?

I'm interested in the list of new features being worked on - especially
JMAP support - and a rough idea of when said features might be expected
to make it into a release.

Thanks!
