Android notification not showing on API 26

Question

I recently upgraded my application to API 26, and notifications no longer work without even changing the code.

val notification = NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle("Title")
                .setContentText("Text")
                .build()
(getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager).notify(1, notification)

Why doesn't it work? Have there been some API changes that I don't know about?
