[github-actions[bot]]

• Fix class BoundedAttributes to have RLock rather than Lock (#3859)
• Remove thread lock by loading RuntimeContext explicitly. (#3763)
• Update proto version to v1.2.0 (#3844)
• Add to_json method to ExponentialHistogram (#3780)
• Bump mypy to 1.9.0 (#3795)
• Fix exponential histograms (#3798)
• Fix otlp exporter to export log_record.observed_timestamp (#3785)
• Add capture the fully qualified type name for raised exceptions in spans (#3837)
• Prometheus exporter sort label keys to prevent duplicate metrics when user input changes order (#3698)
• Update semantic conventions to version 1.25.0. Refactor semantic-convention structure: - SpanAttributes, ResourceAttributes, and MetricInstruments are deprecated. - Attribute and metric definitions are now grouped by the namespace. - Stable attributes and metrics are moved to opentelemetry.semconv.attributes and opentelemetry.semconv.metrics modules. - Stable and experimental attributes and metrics are defined under opentelemetry.semconv._incubating import path. (#3586)
• Rename test objects to avoid pytest warnings ([Rename test objects to avoid pytest warnings #3823] (Rename test objects to avoid pytest warnings #3823))
• Add span flags to OTLP spans and links (#3881)
• Record links with invalid SpanContext if either attributes or TraceState are not empty (#3917)
• Add OpenTelemetry trove classifiers to PyPI packages ([Add OpenTelemetry trove classifiers to PyPI packages #3913] (Add OpenTelemetry trove classifiers to PyPI packages #3913))
• Fix prometheus metric name and unit conversion (#3924) - this is a breaking change to prometheus metric names so they comply with the specification. - you can temporarily opt-out of the unit normalization by setting the environment variable OTEL_PYTHON_EXPERIMENTAL_DISABLE_PROMETHEUS_UNIT_NORMALIZATION=true - common unit abbreviations are converted to Prometheus conventions (s -> seconds), following the collector's implementation - repeated _ are replaced with a single _ - unit annotations (enclosed in curly braces like {requests}) are stripped away - units with slash are converted e.g. m/s -> meters_per_second. - The exporter's API is not changed
• Add parameters for Distros and configurators to configure autoinstrumentation in addition to existing environment variables. ([Auto instrumentation parameters #3864] (Auto instrumentation parameters #3864))
