Compare Source

Added

• opentelemetry-api, opentelemetry-sdk: add support for 'random-trace-id' flags in W3C traceparent header trace flags. Implementations of IdGenerator that do randomly generate the 56 least significant bits, should also implement a is_trace_id_random methods that returns True. (#​4854)
• logs: add exception support to Logger emit and LogRecord attributes (#​4908)
• opentelemetry-exporter-otlp-proto-grpc: make retryable gRPC error codes configurable for gRPC exporters (#​4917)
• opentelemetry-sdk: Add create_logger_provider/configure_logger_provider to declarative file configuration, enabling LoggerProvider instantiation from config files without reading env vars (#​4990)
• opentelemetry-exporter-otlp-json-common: add 'opentelemetry-exporter-otlp-json-common' package for OTLP JSON exporters (#​4996)
• opentelemetry-sdk: Add service resource detector support to declarative file configuration via detection_development.detectors[].service (#​5003)
• opentelemetry-docker-tests: add docker-tests coverage of opentelemetry-exporter-otlp-proto-grpc and opentelemetry-exporter-otlp-proto-http metrics export (#​5030)
• Add registry keyword argument to PrometheusMetricReader to allow passing a custom Prometheus registry (#​5055)
• Add WeaverLiveCheck test util (#​5088)
• opentelemetry-sdk: add load_entry_point shared utility to declarative file configuration for loading plugins via entry points; refactor propagator loading to use it (#​5093)
• opentelemetry-sdk: add sampler plugin loading to declarative file configuration via the opentelemetry_sampler entry point group, matching the spec's PluginComponentProvider mechanism (#​5095)
• opentelemetry-sdk: add propagator plugin loading to declarative file configuration via the opentelemetry_propagator entry point group, matching the spec's PluginComponentProvider mechanism (#​5098)
• opentelemetry-sdk: add exporter plugin loading to declarative file configuration for all three signals (traces, metrics, logs) via the opentelemetry_*_exporter entry point groups, matching the spec's PluginComponentProvider mechanism (#​5128)
• opentelemetry-sdk: add generic resource detector plugin loading to declarative file configuration via the opentelemetry_resource_detector entry point group, matching the spec's PluginComponentProvider mechanism (#​5129)
• opentelemetry-sdk: add additional_properties support to generated config models via custom datamodel-codegen template, enabling plugin/custom component names to flow through typed dataclasses (#​5131)
• Add ability to selectively enable exporting of SDK internal metrics with the OTEL_PYTHON_SDK_INTERNAL_METRICS_ENABLED environment variable. (#​5151)

Changed

• opentelemetry-semantic-conventions: use X | Y union annotation (#​5096)
• opentelemetry-api: update EnvironmentGetter and EnvironmentSetter to use normalized environment variable names (#​5119)
• Apply fixes for UP ruff rule (#​5133)
• opentelemetry-sdk: only load entrypoints for resource detectors if they are configured via OTEL_EXPERIMENTAL_RESOURCE_DETECTORS (#​5145)
• ci: wait for tracecontext server readiness instead of a fixed sleep in scripts/tracecontext-integration-test.sh (#​5149)
• Switch to SPDX license headers and add CI enforcement (#​5177)
• opentelemetry-semantic-conventions: Bump semantic conventions to 1.41.1, this changes the metrics name of K8S_CONTAINER_CPU_LIMIT_UTILIZATION and K8S_CONTAINER_CPU_REQUEST_UTILIZATION. (#​5200)

Removed

• opentelemetry-api: remove third-party importlib-metadata in favor of standard library since Python >= 3.10 is now required (#​3234)
• Drop Python 3.9 support (#​5076)

Fixed

• opentelemetry-sdk: Allow declarative OTLP HTTP exporters to map compression: deflate instead of rejecting it as unsupported. (#​5075)
• Fix incorrect code example in create_tracer() docstring (#​5077)
• opentelemetry-sdk: Fix ProcessResourceDetector to use sys.orig_argv so that process.command, process.command_line, and process.command_args reflect the original invocation for python -m <module> runs (where sys.argv[0] is rewritten to the module path) (#​5083)
• opentelemetry-sdk: fix YAML structure injection via environment variable substitution in declarative file configuration; values containing newlines are now emitted as quoted YAML scalars per spec requirement (#​5091)
• opentelemetry-sdk: Fix mutable attributes reference in metrics, attributes passed to instrument add/record are now copied so that subsequent mutations do not affect recorded data points (#​5106)
• opentelemetry-sdk: make resource detector ordering deterministic (#​5120)
• Fix incorrect type annotation on detectors parameter of get_aggregated_resources (#​5135)
• opentelemetry-api: Enforce W3C Baggage size limits on outbound propagation in W3CBaggagePropagator.inject(). Previously only inbound extraction enforced limits; now inject also caps entries at 180, individual pairs at 4096 bytes, and total header at 8192 bytes per the W3C Baggage spec. The extract path max_pairs limit now counts all size-valid entries rather than only successfully parsed ones. (#​5163)
• opentelemetry-sdk: fix multi-processor force_flush skipping remaining processors when one returns None (#​5179)
• opentelemetry-test-utils: fix weaver live check hanging when weaver log output fills the pipe buffer (#​5208)
