Before today, we would send an email for every Performance or Exception incident if a notification rule was triggered. This meant that if you deployed a new version of your app and your incident notification settings were set to "first in deploy", you'd get two emails if two errors occurred.

Process management refers to various activities around the creation, termination, and monitoring of processes. A process manager is a program that ensures that your applications always stay online after being launched. Process managers can prevent downtime in production by automatically restarting your application after a crash or even after the host machine reboots. They are also useful in development: they auto-restart an app once its source files or dependencies are updated.
