Hi all!
Nimrod 0.3 has been just released with new features and enhancements, the most important one being a brand new metrics store which can be either volatile, for short-living metrics, or persistent, for nearly unlimited metrics and back-in-time history.
Other relevant enhancements are custom log identifiers, allowing users to manually assign a custom name to processed logs, and an improved REST interface.
