v1.18.0

1.18.0 (2026-07-17)

⚠ BREAKING CHANGES

• otelcol.receiver.otlp, otelcol.receiver.faro, otelcol.receiver.jaeger, otelcol.receiver.zipkin, otelcol.receiver.influxdb, otelcol.receiver.splunkhec, otelcol.receiver.datadog, and otelcol.extension.jaeger_remote_sampling now default to idle_timeout = "1m", read_header_timeout = "1m", and write_timeout = "30s" on their HTTP servers, matching upstream default. These were previously being defaulted to "0s". You can explicitly set them to "0s" to restore the previous behavior.
• otelcol.receiver.kafka and otelcol.exporter.kafka: resolve_canonical_bootstrap_servers_only is now a no-op and deprecated. The upstream migration from migration from sarama to `franz-go dropped the behavior. The argument still parses but no longer resolves bootstrap server addresses.
• otelcol.exporter.splunkhec — batcher block removed (upstream deletion in otel-contrib v0.151). Configs using it will fail to load. Migration: move the equivalent fields under sending_queue.batch (enabled → presence of the block; flush_timeout/sizer/min_size/max_size keep their names).
