  <p>Recently we recieved this email from Apple Developer:</p>
  <p><em>&quot;If you still send push notifications with the legacy binary protocol, it's time to update to the HTTP/2-based Apple Push Notification service (APNs) provider API. You'll be able to take advantage of great features, such as authentication with a JSON Web Token, improved error messaging, and per-notification feedback.
  To give you additional time to prepare, the deadline to upgrade to the APNs provider API has been extended to March 31, 2021. We recommend upgrading as soon as possible, as APNs will no longer support the legacy binary protocol after this date.&quot;</em></p>
  <p><strong>My question is: Will PushSharp 4.0.10 still work after March 31, 2021?</strong></p>
