Comment: added RC3 publish date

The goal of this page is to document all the development milestones for the Airflow 3.0 release. This is intended to be a "living" document and reflect plans and progress during the development and test phase of the project.  This is supplemental to the high level timelines in the main Airflow 3.0 page.

This was initially documented in preparation for the dev call on the 10th of October and reviewed as part of that dev call.
