Version 1.44.0/0.65b0

Added

• opentelemetry-docker-tests: Refactor Docker tests to properly validate contents of exported telemetry (#5220)
• opentelemetry-exporter-otlp-common: add shared package for common OTLP utilities (#5252)
• opentelemetry-sdk: add MissingDependencyError exception for declarative configuration and use it for missing optional dependency errors (#5265)
• opentelemetry-sdk: Add ability to refresh process dependent Resource attributes (#5280)
• opentelemetry-sdk: add force_flush method to LogRecordExporter ABC (#5294)
• opentelemetry-sdk: Make it possible to limit the size of stored spans in InMemorySpanExporter (#5296)
• opentelemetry-sdk: add log record limits environment variables OTEL_LOGRECORD_ATTRIBUTE_COUNT_LIMIT and OTEL_LOGRECORD_ATTRIBUTE_VALUE_LENGTH_LIMIT (#5300)
• opentelemetry-sdk: add support for file exporter with declarative config (#5311)
• opentelemetry-sdk: expose SynchronousMultiLogRecordProcessor and ConcurrentMultiLogRecordProcessor publicly (#5327)
• opentelemetry-sdk: point the declarative configuration package README at the shared language support status matrix in the opentelemetry-configuration repo, so Python conformance status lives alongside the other languages instead of being duplicated per language SDK. (#5347)
• opentelemetry-sdk: document that Python-implementation extensions (OTEL_PYTHON_* variables) are bypassed when OTEL_CONFIG_FILE is set. The env-var initialisation path is skipped entirely in favour of the declarative file; honouring these alongside a config file is tracked as a follow-up. (#5353)
• opentelemetry-sdk: wire id_generator from declarative configuration to TracerProvider (#5363)
• opentelemetry-sdk: Add support for activating instrumentors from a declarative configuration file via the instrumentation/development.python section. Instrumentors can declare a configuration attribute to have their options validated through the same type-coercion pipeline used for SDK component configuration. (#5372)
• opentelemetry-sdk: add record_min_max option to ExponentialBucketHistogramAggregation, matching the option already available on ExplicitBucketHistogramAggregation and required by the specification (#5377)

Changed

• opentelemetry-sdk: revert BoundedAttributes RLock back to Lock (#5329)
• docs: update logs example to use opentelemetry-instrumentation-logging (#5344)
• opentelemetry-sdk: bump declarative configuration schema to v1.1.0 (#5345)
• opentelemetry-configuration: declarative configuration moves from opentelemetry.sdk._configuration into the new public opentelemetry-configuration package (opentelemetry.configuration namespace), published experimentally. opentelemetry-sdk[file-configuration] continues to work as an alias that installs opentelemetry-configuration alongside the SDK. (#5356)
• opentelemetry-api: remove env carrier environment snapshot caching, you now have to pass explicitly the mapping where to get the environment variables from as the EnvironmentGetter.get first argument. (#5366)
• opentelemetry-semantic-conventions: bump to 1.42.0 (#5410)
• opentelemetry-semantic-conventions: bump to 1.43.0 (#5413)

Removed

• opentelemetry-api, opentelemetry-sdk: Removed deprecated Events API/SDK. Use LogRecord with the event_name field set instead. (#5293)

Fixed

• opentelemetry-sdk: Optimize LogRecord memory in BatchLogRecordProcessor by clearing the Context object before buffering. This is a potentially breaking change for custom log exporters that access context from the exported ReadableLogRecord, as the context will now be an empty Context() instead of the original. (#4977)
• opentelemetry-sdk: drop non-finite measurements (NaN and Inf) at the instrument level to prevent permanent aggregation poisoning (#5336)
• opentelemetry-sdk: raise ValueError when ExplicitBucketHistogramAggregation boundaries are not strictly increasing or finite (#5340)
• opentelemetry-sdk: ProcessResourceDetector no longer collects or emits process.command_args and process.command_line by default since the values are not sanitized and may contain sensitive information. Users who depend on these resource attributes must pass include_command_args=True. (#5364)
• opentelemetry-exporter-otlp-proto-http: fix the OTLP HTTP metric exporter self-observability metrics over-counting data points when max_export_batch_size splits a batch; each split now reports its own data-point count instead of the whole-batch count. (#5370)
• opentelemetry-api: Prevent in-place mutation of Context via inherited dict methods (#5399)
