Updated OpenTelemetry.Extensions.Hosting from 1.20.0 to 1.20.1.

Release notes

Sourced from OpenTelemetry.Extensions.Hosting's releases.

1.20.1

For highlights and announcements pertaining to this release see: Release Notes > 1.20.1.

The following changes are from the previous release 1.20.0.

  • NuGet: OpenTelemetry v1.20.1

    • Fixed a possible race condition on ARM64 when multiple threads record the
      first measurement with no tags, or the first overflow measurement, that could
      cause the measurement to be recorded incorrectly.
      (#​7951)

    • Fixed self-diagnostics preamble redaction of quoted or encoded PEM material
      and prefixed JWTs.
      (#​7955)

    • Fixed default HTTP client log filtering when registering the OTLP log exporter
      through OpenTelemetryLoggerOptions.
      (#​7959)

    • Fixed legacy self-diagnostics logging terminating the process when the log
      file is truncated or the log volume runs out of space.
      (#​7956)

    • Experimental (pre-release builds only): Fixed Logger.EmitLog ignoring
      instrumentation suppression, which could cause recursive exports or deadlocks.
      (#​7961)

    • Fixed delta double counters losing subsequent measurements after a non-finite
      or large value and idle metric points with a NaN value failing to be reclaimed.
      (#​7963)

    • Improve the assignment of values to exponential histogram buckets when the
      value is near a bucket boundary by using a pre-computed lookup table.
      (#​7911)

    • Fixed LogRecords being returned to the shared pool while still queued for
      export when an exporter stops enumerating a single-item or array
      Batch<LogRecord> early which could cause a BatchLogRecordExportProcessor
      on the same provider to export missing or incorrect data.
      (#​7965)

    • Fixed a SuppressInstrumentationScope.Enter() reference count never being
      released when the Activity it was entered for is not recorded, which caused
      all subsequent telemetry in that execution context to be suppressed.
      (#​7966)

    • Self-diagnostics log files, whether configured through OTEL_DIAGNOSTICS.json
      or SelfDiagnosticsOptions, are now always created as new files.
      (#​7968)
