Differences between v3 and v2 of YouTube API

Question

I'm doing some new work using the YouTube API. I know there are two versions, v2 and v3, but I can't find the differences anywhere. What are the differences?

I know v3 is labeled "experimental". But:

• What's better about it?
• Other than being experimental, what's worse about it?
• Will v2 be phased out?
• For new dev work, should I use v2 or v3

Answer 1

Some answers (in my opinion ..)

What's better about it?

• Search videos, channels and playlists using freebase topics

• Retrieve activities

Other than being experimental, what's worse about it?

• Changes in API calls that you use in your app

For new dev work, should I use v2 or v3

• I think the answer depends on what your application should do and the type of application
