Official update signal
The Roblox games API exposes the experience update timestamp. It does not expose a patch-note body.
What videos add
Video titles and captions can show that players encountered a floor, pack, tournament, or card event around a date. They help guide what needs a current in-game check.
How to read the tracker
Each video is a supporting reference with a date. It never replaces a creator announcement or the current in-game interface.
