For Alert criteria Sentry currently supports filtering issues from the latest release:
While this is a neat feature, it doesn’t entirely cover some scenarios. For instance, we rollout our releases gradually and there is often multiple “latest” release available online. Naturally, we are interested in monitoring a couple of them, not just the latest one.
It would be nice if the filter is extended so that one can specify N number of latest releases that should be monitored for alert.
