Feature Request: Notifications for newer charts if the version range is pinned

[acidicX]

Hi,

we are using a pinned version range on the charts for most of our installed helm releases, like described here:
https://fluxcd.io/flux/use-cases/helm/#automatic-release-upgrades

It would be great if the controller could send a notification about a new helm release that is newer than the pinned range. Just as an info to look into it. Otherwise you need to monitor all helm charts for newer versions, which is quite difficult and a lot of manual work.

Flux already has everything in place to monitor this:

• it knows the pinned range for a specific release
• it has access to the helm charts and fetches the versions automatically
• it has access to a notification system

That would be an awesome addition to an already great system :)
