Changelog

[0.4.0] - 2026-08-23

Added

• :address-lookup and :telemetry-address-lookup client options accept a 0-arg Clojure function for dynamic service discovery / address refresh.
• stop!, distinct from close, invoking the client's explicit .stop().
• telemetry-metric wraps sendTelemetryMetric (telemetry must be enabled).
• Unix-socket (unixstream://), telemetry-builder, and close shutdown test coverage.
• Metric names, sample rates, cardinalities, event alert-types/priorities, and service-check statuses are now validated at the point of use, raising ex-info with the offending option/value/accepted-set instead of failing later with an opaque Java NullPointerException.

Fixed

• client no longer unconditionally sets localhost:8125 on the builder; host/port are now opt-in overrides, so the underlying Java client's own DD_AGENT_HOST/DD_DOGSTATSD_PORT/DD_DOGSTATSD_URL environment defaulting takes effect when the caller omits them.

[0.3.0] - 2026-07-16

Added

• service-check gains :timestamp, :cardinality, and :check-run-id options.
• event gains :cardinality and :priority (:normal/:low) options.
• set-metric gains a per-call :cardinality option.

Fixed

• Numeric metrics (count, count-at, gauge, gauge-at, histogram, distribution) now dispatch on value type: integers use the long/int overloads (preserving precision above 2^53) and floating/ratio values use the double overloads (preserving fractional values). Previously fractional deltas were truncated to long.

[0.2.0] - 2026-07-16

Added

• Expose the full NonBlockingStatsDClientBuilder surface through client.
• Add per-call :sample-rate and :cardinality options to metric functions.
• Add timestamped count and gauge metrics.

[0.1.3] - 2026-07-12

Changed

• Migrate the build to deps.edn and tools.build, with Leiningen supported via lein-tools-deps.

[0.1.2] - 2026-06-26

• Relicense to EPL 2.0 (corrects the published POM license metadata; no code change).

[0.1.1] - 2026-06-14

• Standardize README structure and badges (docs only).

[0.1.0] - 2026-06-07

• Initial release.
• Idiomatic Clojure wrapper over the official Datadog java-dogstatsd-client 4.4.5: client, increment, decrement, count, gauge, histogram, distribution, timing, set-metric, event, service-check.
• Tags accept a Clojure map ({:env "prod"}) or a seq of strings.
