No, you’ve seen no “official” announcement of this release – that’s the whole point. See: Anki 25.06 Beta - #167 by dae .
There’s no uncertainty about the stability of this version, it is just being rolled out more slowly to address any issues with the new installer. As I mentioned above, it’s the the unofficial announcements [on Reddit, on Discord] that are the cause of the confusion – and where those screenshots are coming from.
Those folks are certainly not the ones getting confused by this.
