SHA-2 Apple certificate

[Alex Me]

Hi

Apple send me an email about new certificate to include to send push notitification. 

"To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate."

I'm using Pushy and P12 cerficate right now. Is there some changes i have to do?

Thanks
