## Incompatible changes
* These deprecated configuration keys are no longer supported and will cause an error on startup if used in a veneur config file:
** `api_hostname` - replaced in 1.5.0 by `datadog_api_hostname`
** `key` - replaced in 1.5.0 by `datadog_api_key`
** `trace_address` - replaced in 1.7.0 by `ssf_listen_addresses`
** `trace_api_address` - replaced in 1.5.0 by `datadog_trace_api_address`
** `ssf_address` - replaced in 1.7.0 by `ssf_listen_addresses`
** `tcp_address` and `udp_address` - replaced in 1.7.0 by `statsd_listen_addresses`
* `api_hostname` - replaced in 1.5.0 by `datadog_api_hostname`
* `key` - replaced in 1.5.0 by `datadog_api_key`
* `trace_address` - replaced in 1.7.0 by `ssf_listen_addresses`
* `trace_api_address` - replaced in 1.5.0 by `datadog_trace_api_address`
* `ssf_address` - replaced in 1.7.0 by `ssf_listen_addresses`
* `tcp_address` and `udp_address` - replaced in 1.7.0 by `statsd_listen_addresses`
* These metrics have changed names:
** Datadog, MetricExtraction, and SignalFx sinks now emit `veneur.sink.metric_flush_total_duration_ns` for metric flush duration and tag it with `sink`
** Datadog, Kafka, MetricExtraction, and SignalFx sinks now emits `sink.metrics_flushed_total` for metric flush counts and tag it with `sink`
** Datadog and LightStep sinks now emit `veneur.sink.span_flush_total_duration_ns` for span flush duration and tag it with `sink`
** Datadog, Kafka, MetricExtraction, and LightStep sinks now emit `sink.spans_flushed_total` for metric flush counts and tag it with `sink`
* Datadog, MetricExtraction, and SignalFx sinks now emit `veneur.sink.metric_flush_total_duration_ns` for metric flush duration and tag it with `sink`
* Datadog, Kafka, MetricExtraction, and SignalFx sinks now emits `sink.metrics_flushed_total` for metric flush counts and tag it with `sink`
* Datadog and LightStep sinks now emit `veneur.sink.span_flush_total_duration_ns` for span flush duration and tag it with `sink`
* Datadog, Kafka, MetricExtraction, and LightStep sinks now emit `sink.spans_flushed_total` for metric flush counts and tag it with `sink`
* Veneur's internal metrics are no longer tagged with `veneurlocalonly`. This means that percentile metrics (such as timers) will now be aggregated globally.


## Added
* `veneur-emit` now infers parent and trace IDs from the environment (using the variables `VENEUR_EMIT_TRACE_ID` and `VENEUR_EMIT_PARENT_SPAN_ID`) and sets these environment variables from its `-trace_id` and `parent_span_id` when timing commands, allowing for convenient construction of trace trees if traced programs call `veneur-emit` themselves. Thanks, [antifuchs](https://github.com/antifuchs)
* The Kafka sink for spans can now sample spans (at a rate determined by `kafka_span_sample_rate_percent`) based off of traceIDs (by default) or a tag's values (configurable via `kafka_span_sample_tag`) to consistently sample spans related to each other. Thanks, [rhwlo](https://github.com/rhwlo)!
