Communicate release to support early

[barmac]

What should we do?

Communicate the release (version, changelog link, security notes if necessary) to the support at latest on Friday before the release. We could potentially automate this to be done once the release is built.
There is no need to communicate closed support related issues, but we can do that jointly.

Why should we do it?

This is required to draft the release notes early to be ready for the release public announcement.
