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)

A tiny hop, a version leap,
From fifteen-three to sixteen's keep,
The telemetry flows anew,
One line changed — the rabbit knew
Small steps still make the garden grow! 🐇✨
