Sentry is a modern error logging and aggregation platform.
It’s important to note that Sentry should not be thought of as a log stream, but as an aggregator. It fits somewhere in-between a simple metrics solution (such as Graphite) and a full-on log stream aggregator (like Logstash).
Milestones releases are 1.3 or 1.4, and our deprecation policy is to a two version step. For example, a feature will be deprecated in 1.3, and completely removed in 1.4.
