Major Mobile Push Upgrades

PubNub now supports using the updated interface to the Apple notification service (APNS HTTP/2). We have fully implemented this new service as well as supporting several new features that it enables. You can now use tokens from your developer account instead of push certificates. This vastly simplifies the process of securing the connection - no more need to generate certificates, which is an error prone process. Simply specify your token using cut and paste.

This also provides the ability to send a single message to multiple different apps registered to your Apple developer account. The process to remove a device from the service when a user deletes an app from their device is now much faster, and several other benefits. It will be rolled out shortly to all users, but if you want to use it in the meantime please contact
