It seems like their used to be, but I don’t recall exactly what the timeframe is. Maybe 30 days, or between the time something is announced and available for sale, if those aren’t the same date. And maybe that is only for Photoshop, not Lightroom.
I would ask someone in Adobe Sales, a chat session, preferably, so you can documentation of what they say.
Do you have Photoshop or Lightroom, now?
