• Update OTLP proto to v1.7 #4645.
• Add event_name as a top level field in the LogRecord. Events are now simply logs with the event_name field set, the logs SDK should be used to emit events (#4652).
• Update OTLP gRPC/HTTP exporters: the export timeout is now inclusive of all retries and backoffs. A +/-20% jitter was added to all backoffs. A pointless 32 second sleep that occurred after all retries had completed/failed was removed. (#4564).
• Update ConsoleLogExporter.export to handle LogRecord's containing bytes type in the body (#4614).
• opentelemetry-sdk: Fix invalid type: ignore that causes mypy to ignore the whole file (#4618)
• Add span_exporter property back to BatchSpanProcessor class (#4621)
• Fix license field in pyproject.toml files (#4625)
• Update logger level to NOTSET in logs example (#4637)
• Logging API accepts optional context; deprecates trace_id, span_id, trace_flags. (#4597) and (#4668)
• sdk: use context instead of trace_id,span_id for initializing LogRecord (#4653)
• Rename LogRecordProcessor.emit to on_emit (#4648)
• Logging API hide std_to_otel function to convert python logging severity to otel severity (#4649)
• proto: relax protobuf version requirement to support v6 (#4620)
• Bump semantic-conventions to 1.36.0 (#4669)
