The Logs and Metrics API and SDK remain stable, with no breaking changes in this release. The OTLP Exporters and the Distributed Tracing API/SDK remain in pre-stable states (Release-Candidate and Beta respectively), and this release introduces a small number of intentional breaking changes in those areas to prepare them for stabilization.</p> <p>For detailed changelogs of individual crates, please refer to their respective changelog files. This document serves as a summary of the main changes.</p> <h2>Key Changes</h2> <h3>Metrics SDK</h3> <ol> <li> <p><strong>Bound instruments (experimental)</strong>: Added <code>Counter::bind()</code> and <code>Histogram::bind()</code> returning pre-bound measurement handles (<code>BoundCounter<T></code>, <code>BoundHistogram<T></code>). Bound instruments resolve the attribute-to-aggregator mapping once at bind time and cache the result, eliminating per-call HashMap lookups on the hot path. Benchmarks show ~28x speedup for counter operations and ~9x for histograms. Gated behind the <code>experimental_metrics_bound_instruments</code> feature flag.</p> </li> <li> <p><strong>Delta collection efficiency</strong>: Delta metrics collection now uses in-place eviction instead of draining the HashMap on every collect cycle. Stale attribute sets that received no measurements since the last collection are evicted.</p> </li> <li> <p><strong>Stable <code>Aggregation</code> API</strong>: <code>Aggregation</code> and <code>StreamBuilder::with_aggregation()</code> are now stable and no longer require the <code>spec_unstable_metrics_views</code> feature flag.</p> </li> </ol> <h3>Logs</h3> <ol> <li> <p><strong>Tracing-span attribute enrichment (experimental)</strong>: The <code>opentelemetry-appender-tracing</code> crate can now copy attributes from active <code>tracing</code> spans onto each emitted log record. ("Span" here refers to <code>tracing::span!</code>, not an <code>opentelemetry::trace::Span</code>.) Enrichment is disabled by default with zero per-span overhead, and is gated behind the new <code>experimental_span_attributes</code> cargo feature.</p> </li> <li> <p><strong><code>spec_unstable_logs_enabled</code> removed</strong>: The capability (and the backing specification) is now stable and is enabled by default. The feature flag has been removed.</p> </li> </ol> <h3>Distributed Tracing (Beta)</h3> <p>The Distributed Tracing API and SDK remain in beta.
