Hi Huy,
I confirm the feature status is still "Unplanned" at this stage. That means no specific time frame is assigned yet. As soon as we move a task to the short-term backlog, the status will change to "Planned" and most likely a release number will appear as well.
Things are dynamic, and the best way to stay updated with the feature status is to keep following the public item here.
If we can assist with more information, I would be glad.
Regards,
Hristian Stefanov
