New Relic has enhanced its Query Language (NRQL) to improve user experience and query capabilities, particularly with the introduction of wildcards that allow for easier querying and charting of multiple metrics together, eliminating the need to manually add individual metrics. The new NRQL also handles null, empty strings, empty sets, and NaN values more accurately, providing expected results in queries. These updates aim to make it faster and easier for users to explore their telemetry data and make informed decisions with New Relic dashboards and analytics.
