4.5 Analytic - how to?

In 4.5 there is new Analytics - anyone know where can I find blueprint nodes for this?

New: Added a Analytics Blueprint Library as a plugin.
This allows Blueprint only projects access to the native Analytics APIs.
This Blueprint Library uses the default Analytics provider registered for your project.

New: Added a file based analytics provider as a plugin.
This provider writes analytics data to a file in json format.
Use this to debug your analytic event capturing.

New: Added Apsalar analytics for iOS as a plugin.
This analytics provider sends the data to Apsalar’s cloud service (see www.apsalar.com for more details).
This plugin requires information from your Apsalar account to send the analytics events.

4.5 comes out and still no info about the analytics - I will be really grateful if someone can tell me where I can find it.

I’m also interested to get more details about it.

Blueprint Analytics Plugin is a built-in plugin that you can enable for your project, as documented in Blueprint Analytics Plugin | Unreal Engine Documentation
