How does the new detection work

There’s a new help article explaining how the New Detection feature works on elmah.io: https://docs.elmah.io/how-does-the-new-detection-work/. New Detection is used to set the isNew flag on log messages and is used in most of the emails and apps available on elmah.io. Understanding the details of this feature is not important for all users but having some documentation around the subject should be able to help you if you start seeing messages that you believe should be considered unique or the other way around.
