• Fix a panic when a value stored with Context::with_value() calls
  Context::current() from its Drop implementation.
• Expand tracing documentation on async context propagation and child spans
  (#​828).
• Document the panic contract for observable metric callbacks (Callback and
  AsyncInstrumentBuilder::with_callback).

open-telemetry/opentelemetry-rust (opentelemetry-otlp)

v0.33.1

Compare Source

Released 2026-Oct-08

• Declare the OTLP exporters for Logs and Metrics stable after the 0.33.0 release-candidate period. Tracing remains in beta.
• Update OpenTelemetry dependencies to 0.33.1, including SDK fixes and OTLP/JSON interoperability fixes in opentelemetry-proto.

v0.33.1

Compare Source

Released 2026-Oct-08

• Emit a one-time internal error diagnostic when the default PeriodicReader
  worker thread panics (such as from an observable metric callback), and document
  the callback panic contract.
  (#​3640)
• Added Sampler::parent_based(root), returning a ParentBasedSampler that lets
  all 5 branches of the ParentBased sampler spec be configured independently
  (root, and remote/local parent that is/isn't sampled) via with_remote_parent_sampled,
  with_remote_parent_not_sampled, with_local_parent_sampled, and
  with_local_parent_not_sampled. Previously Sampler::ParentBased only let you
  override the root case; the other 4 were fixed to the spec defaults. Unset
  branches keep those same defaults, so this is purely additive.
  (#​3657)
• Fixed Histogram, Sum, LastValue, and PrecomputedSum aggregators (and
  their bound-instrument handles) silently accepting NaN/Infinity
  measurements. For Histogram and Sum, a single NaN measurement
  permanently corrupted the cumulative sum/total for the rest of the
  process's lifetime (x + NaN == NaN); LastValue and PrecomputedSum
  self-healed on the next valid measurement but still exported one bad value
  in the meantime, and PrecomputedSum under delta temporality corrupted two
  export cycles. Non-finite measurements are now dropped before recording,
  matching ExponentialHistogram's existing behavior.
  (#​3656)
• Fixed SdkTracer inheriting an invalid parent span context (e.g. a context
  carrying an invalid active span context). Such a parent is now treated as no
  parent: the span gets a freshly generated trace id instead of the parent's
  all-zero one, and is not recorded as a child of it.
  (#​3657)
• Log metric export failures at ERROR level in PeriodicReader, making
  failures such as an unreachable collector visible without enabling DEBUG
  logging.
  (#​3754)
