1.16.0-rc.1

The following changes are from the previous release 1.15.3.

  • NuGet: OpenTelemetry v1.16.0-rc.1

    • Stop validating View-provided metric stream Name against the instrument
      name syntax, per
      spec clarification.
      (#​7300)

    • Fix incorrect validation of OTEL_BSP_* and OTEL_BLRP_* environment
      variables.
      (#​7187)

    • Fix observable instrument callbacks running once per reader instead of
      once per collection cycle.
      (#​7188)

    • Added exception safety for user-supplied ExemplarReservoir implementations.
      Exceptions thrown from Offer are now caught and logged rather than propagating
      out of Counter.Add/Histogram.Record.
      (#​7277)

    • Update OpenTelemetrySdkEventSource to support the W3C randomness flag.
      (#​7301)

    • Added ObservedTimestamp property to LogRecord.
      (#​6979)

    • Breaking Change Explicit histogram boundaries no longer allow more than
      10 million values.
      (#​7165)

    • Fixed a circular reference which could cause a LoggerProvider to fail to
      resolve when one of its dependencies depends on ILogger or ILoggerFactory.
      As part of this fix the LoggerProvider resolved from dependency injection
      is now created lazily when the first logger is created rather than when
      ILoggerProvider or ILoggerFactory is resolved. A consequence is that any
      invalid configuration now surfaces when the first log record is written instead
      of when the logging services are resolved.
      (#​7308)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.16.0-rc.1

    • Experimental (pre-release builds only):
      Add support for using environment variables as context propagation carriers.
      (#​7174)

    • Fix BaggagePropagator to correctly follow Key and Value Encoding rules as per
      ... (truncated)

1.16.0-beta.1

The following changes are from the previous release 1.15.3-beta.1.

  • NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.16.0-beta.1

    • Fixed scrape response cache freshness using monotonic time so it is not
      affected by NTP system clock adjustments.
      (#​7253)

    • Breaking Change Removed DisableTimestamp property from
      PrometheusAspNetCoreOptions.
      (#​7176)

    • Fixed the serialization of NaN, PositiveInfinity, and NegativeInfinity
      values in Prometheus metrics to be compliant with the specification.
      (#​7179)

    • Fixed loss of precision when serializing double and float values in
      Prometheus metrics to be compliant with the specification by using 17
      significant digits to represent such values.
      (#​7179)

    • Fix non-ASCII characters in metric names and unit strings not being sanitized
      correctly during Prometheus serialization.
      (#​7184)

    • Fix case where reader tracking could be reset while readers were still active.
      (#​7190)

    • Improve Accept header handling for format negotiation so OpenMetrics is
      selected correctly by considering whitespace and q weights.
      (#​7208)

    • Emit OpenMetrics exemplars for counters and histogram buckets.
      (#​7222)

    • Fix incorrect handling of untyped metrics when using OpenMetrics format.
      (#​7219)

    • Fix Prometheus/OpenMetrics serialization to emit metric and label names
      containing _ instead of dropping them and prefixing leading digits.
      Invalid characters are replaced with _ instead of being dropped.
      (#​7209)

    • Add escaping=underscores to the Accept header handling for content
      negotiation so OpenMetrics are handled correctly.
      (#​7209)

    • Omit histogram _sum and _count in OpenMetrics when negative bucket
      thresholds are present.
      (#​7221)
