Last year Chrome announced it's discontinuing support for it's notification center (http://www.theverge.com/2015/10/14/9531133/google-removing-chrome-notification-center-windows-mac http://www.theverge.com/2015/10/14/9531133/google-removing-c...) on Mac and PC, so I imagine they are replacing it with native versions of each OS. To note, Stable is always several weeks behind Canary, so you can see the latest build of the notifications which shows more info than the stable version.
