5.9.1 / 2026-08-14

• [BUGFIX] Prevent a panic when closing a Windows named pipe client that never sent a metric. See #397[].
• [BUGFIX] Fix an off-by-one error in reservoir sampling that biased which samples were kept once WithMaxSamplesPerContext() was reached. See #395[].

5.9.0 / 2026-06-24

• [IMPROVEMENT] Improve aggregator performance: inline shard allocation, FNV-1a metric context hashing, and cache-line padding on shards. See #389[].
• [IMPROVEMENT] Make externalEnv an atomic to reduce lock contention on the sampling hot path. See #380[], thanks [@​KowalskiThomas][].
• [IMPROVEMENT] Optimize origin-detection condition check order. See #381[], thanks [@​KowalskiThomas][].
• [BUGFIX] Fix payload length calculation for aggregated metrics to prevent datagram truncation when container ID, external env, or cardinality are set. See #368[].
• [BUGFIX] Fix data race when reading the origin-detection container ID. See #379[], thanks [@​KowalskiThomas][].
• [BUGFIX] Fix telemetry metrics not using the client's configured cardinality setting. See #367[].
• [BUGFIX] Replace vulnerable logrus v1.7.0 transitive dependency (CVE-2025-65637). See #358[], thanks [@​nadavshatz][].
