Changes from 0.10.0:

API

Breaking changes:

  • The SPI interfaces have moved to a package (not a module) separate from the API packages, and now live in io.opentelemetry.spi.* package namespace.
  • Builder classes have been moved to the top level, rather than being inner classes.
    For example, rather than io.opentelemetry.api.trace.Span.Builder, the builder is now in its own top-level class: io.opentelemetry.api.trace.SpanBuilder.
    Methods to create the builders remain in the same place as they were before.
  • SpanBuilder.setStartTimestamp, Span.end, and Span.addEvent methods which accept a timestamp now accept a timestamp with a TimeUnit instead of requiring a nanos timestamp

Enhancements:

  • Versions of SpanBuilder.setStartTimestamp, Span.end, and Span.addEvent added which accept Instant timestamps
  • Setting the value of the io.opentelemetry.context.contextStorageProvider System property to default will enforce that
    the default (thread local) ContextStorage will be used for the Context implementation, regardless of what SPI implementations are
    available.

Miscellaneous:

  • Invalid W3C TraceState entries will now be silently dropped, rather than causing the invalidation of the entire TraceState.

SDK

Breaking Changes:

  • The builder class for the OpenTelemetrySdk now strictly requires its components to be SDK implementations.
    You can only build an OpenTelemetrySdk with TracerSdkProvider and MeterSdkProvider instances.

Enhancements:

  • An API has been added to the SDK's MeterProvider implementation (MeterSdkProvider) that allows the end-user to configure
    how various metrics will be aggregated. This API should be considered a precursor to a full "Views" API, and will most likely
    evolve over the coming months before the metrics implementation is complete. See the javadoc for MeterSdkProvider.registerView() for details.

Miscellaneous:

  • The SpanProcessor interface now includes default method implementations for the shutdown() and forceFlush() methods.
  • The BatchRecorder implementation has been updated to actually batch the recordings, rather than simply passing them through.

Extensions

Breaking Changes:

  • The @WithSpan annotation has been moved to the io.opentelemetry.extension.annotations package in the opentelemetry-extension-annotations module

Bugfixes:

  • The memory pool metrics provided by the MemoryPools class in the opentelemetry-extension-runtime-metrics module
    have been fixed to properly report the committed memory values.

Enhancements:

  • A new module has been added to assist with propagating the OTel context in kotlin co-routines.
    See the opentelemetry-extension-kotlin module for details.
