• opentelemetry-sdk: Add host resource detector support to declarative file configuration via detection_development.detectors[].host (#5002)
• opentelemetry-sdk: Add container resource detector support to declarative file configuration via detection_development.detectors[].container, using entry point loading of the opentelemetry-resource-detector-containerid contrib package (#5004)
• opentelemetry-sdk: Add create_tracer_provider/configure_tracer_provider to declarative file configuration, enabling TracerProvider instantiation from config files without reading env vars (#4985)
• Enabled the flake8-tidy-import plugins rules for the ruff linter. These rules throw warnings for relative imports in the modules. (#5019)
• opentelemetry-sdk: Fix AttributeError in ExplicitBucketHistogramAggregation when applied to non-Histogram instruments without explicit boundaries (#5034)
• Fix BatchLogRecordProcessor default schedule_delay_millis from 5000ms to 1000ms to comply with the OTel specification. Note: logs may be exported 5x more frequently by default (e.g. for users who don't explicitly set the OTEL_BLRP_SCHEDULE_DELAY env var). (#4998)
• opentelemetry-sdk: Add process resource detector support to declarative file configuration via detection_development.detectors[].process (#5001)
• opentelemetry-sdk: Add shared _parse_headers helper for declarative config OTLP exporters (#5021)
• opentelemetry-api: Replace a broad exception in attribute cleaning tests to satisfy pylint in the lint-opentelemetry-api CI job
• opentelemetry-sdk: Add create_meter_provider/configure_meter_provider to declarative file configuration, enabling MeterProvider instantiation from config files without reading env vars (#4987)
• opentelemetry-sdk: Add create_resource and create_propagator/configure_propagator to declarative file configuration, enabling Resource and propagator instantiation from config files without reading env vars (#4979)
• opentelemetry-sdk: Map Python CRITICAL log level to OTel FATAL severity text per the specification (#4984)
• opentelemetry-sdk: Add file configuration support with YAML/JSON loading, environment variable substitution, and schema validation against the vendored OTel config JSON schema (#4898)
• Fix intermittent CI failures in getting-started and tracecontext jobs caused by GitHub git CDN SHA propagation lag by installing contrib packages from the already-checked-out local copy instead of a second git clone (#4958)

• opentelemetry-sdk: upgrade vendored OTel configuration schema from v1.0.0-rc.3 to v1.0.0 (#4965)
• improve check-links ci job (#4978)
• Resolve some Pyright type errors in Span/ReadableSpan and utility stubs (#4973)
• opentelemetry-exporter-prometheus: Fix metric name prefix (#4895)
• opentelemetry-api, opentelemetry-sdk: Add deepcopy support for BoundedAttributes and BoundedList (#4934)
• opentelemetry-proto-json, opentelemetry-codegen-json: Implement custom protoc plugin to generate OTLP JSON class definitions (#4910)
• Add configurable max_export_batch_size to OTLP HTTP metrics exporter (#4576)
• opentelemetry-sdk: Implement experimental Meter configurator (#4966)
• opentelemetry-exporter-otlp-proto-http: use consistent protobuf for export request (#5015)
• opentelemetry-sdk: cache TracerConfig into the tracer, this changes an internal interface. Only one Tracer with the same instrumentation scope will be created (#5007)
• Redo OTLPMetricExporter unit tests of max_export_batch_size to use real export (#5036)
• opentelemetry-sdk: Implement experimental Logger configurator (#4980)
