When it comes to patches, we often don't realize there is a patch to download until our enterprise system breaks and someone alerts us that our services and apps aren't working. It would be great to have an email subscription that sends out notifications when a new patch is available to your version of enterprise so the patch can be installed proactively and minimize a disruption in service.
The patchnotification utility is not what I'm looking for; while its a great tool for downloading patches once you notice a service disruption and run the tool, I'm looking for an email alert that notifies me when the patch itself is released.
