RC5 and NgZone

I have a variable that is syncronized to a value in a CouchDB database via PouchDB and shown in the view with two-way data binding. In RC4 any remote changes in the database were immediately visible in the view. In RC5 I need to run the update inside this.zone.run(()=> {}), where zone is a NgZone, to achieve the same.

  • What has changed?
  • Are there any disadvantages of using my own zones?

I’m new to Angular2. Thanks…
