CTM or Wishes schedule release?

How far in advance are these times released? My trip is in January and they aren’t scheduled from what I can see.
Also, are these subject to time changes as well? I have ADR at CRT for 8:15 bc that’s all I could get so it’s likely we will be in the castle during fireworks.

Wishes schedule changed within the 2 week period before our trip last year. They are always subject to change. I’ll be checking at 2 weeks prior and then confirming in the park map/time guide arrival day.
