I was looking into the changelist for a movie. Here is the URL:

http://api.themoviedb.org/3/movie/267860/changes?api_key=&start_date=2016-05-30&end_date=2016-06-10

I have a couple of questions there:

1. In the homepage key, the updated JSON looks like this:

"key":"homepage", "items":[
{
"id":"574c4f529251410eec000055", "action":"added", "time":"2016-05-30 14:33:54 UTC", "iso_639_1":"fi" } ]

What does this mean? What is the new value? From the current movie page, given by https://api.themoviedb.org/3/movie/267860?api_key=, it looks like https://www.facebook.com/LondonHasFallenOfficial is the value.

1. In the "Overview" key, there seems to be additions and updates in Finnish and German languages. However, where at all these values are needed? Doesn't the overview contain only English text in the movie API itself?

2. The "title" key has lots of updates, in different languages like Portuguese. However, what is the role of the "alternate titles" key then? Isn't that supposed to contain all other title updates?

3. In the "videos" key, one video has been added - whose name is "קדימון בעברית", and key is "8BPS91R2LD4". What does that mean?
