Re: Q4 launch timeline
Priya Shah
Marketing needs final copy by Oct 28 if we keep the Nov 3 launch. Can engineering confirm the release candidate is on track?
Daniel Kim
RC is on track for Oct 30. QA needs two extra days for the payments flow, so Nov 3 is tight but possible.
Priya Shah
If QA slips, should we move the launch to Nov 5 instead?
Summary:
- Launch planned for Nov 3
- RC due Oct 30, QA needs 2 more days
- Option: move launch to Nov 5
