We know, but is not the same to comment in a public event with a limited audience, to post in the forum.
If we make changes about what Paul said in the event, nothing happens. But if we post now the release notes, someone would complain if not everything is available in the release.
Some features are known because we commented it in other posts: macros, roofing options, improved mapping, style linking, etc. But a detailed list is not available yet.
Thanks for your understanding. We are making our best effort to release first beta as soon as possible.
