PJSIP and Dynamic IPs in Asterisk 15.2.0

I just came across this interesting article on first class support for dynamic IPs coming to chan_pjsip in Asterisk 15.2.0.

It looks like currently distro SNG7 bundles Asterisk 15.1.3. So, my questions are:

1. Is there an ETA on when 15.2.0 is expected to land in the distro?
2. When it does, will there be any UI for interacting with the new DNS Manager (dnsmgr.conf)?
