([#&#8203;4647](https://redirect.github.com/open-telemetry/opentelemetry-python/pull/4647))

  **Migration Guide:**

  `LogData` has been removed. Users should update their code as follows:

- **For Log Exporters:** Change from `Sequence[LogData]` to
`Sequence[ReadableLogRecord]`
    ```python
    # Before
    from opentelemetry.sdk._logs import LogData
    def export(self, batch: Sequence[LogData]) -> LogRecordExportResult:
        ...

    # After
    from opentelemetry.sdk._logs import ReadableLogRecord
def export(self, batch: Sequence[ReadableLogRecord]) ->
LogRecordExportResult:
        ...
    ```

- **For Log Processors:** Use `ReadWriteLogRecord` for processing,
`ReadableLogRecord` for exporting
    ```python
    # Before
    from opentelemetry.sdk._logs import LogData
    def on_emit(self, log_data: LogData):
        ...

    # After
from opentelemetry.sdk._logs import ReadWriteLogRecord,
ReadableLogRecord
    def on_emit(self, log_record: ReadWriteLogRecord):
        # Convert to ReadableLogRecord before exporting
        readable = ReadableLogRecord(
            log_record=log_record.log_record,
            resource=log_record.resource or Resource.create({}),
            instrumentation_scope=log_record.instrumentation_scope,
            limits=log_record.limits,
        )
        ...
    ```

- **Accessing log data:** Use the same attributes on
`ReadableLogRecord`/`ReadWriteLogRecord`
- `log_record.log_record` - The API LogRecord (contains body, severity,
attributes, etc.)
    - `log_record.resource` - The Resource
- `log_record.instrumentation_scope` - The InstrumentationScope (now
included, was in LogData before)
    - `log_record.limits` - The LogRecordLimits
- Mark the Events API/SDK as deprecated. The Logs API/SDK should be used
instead, an event is now a `LogRecord` with the `event_name` field set

([#&#8203;4654](https://redirect.github.com/open-telemetry/opentelemetry-python/pull/4654)).
- Fix type checking for built-in metric exporters

([#&#8203;4820](https://redirect.github.com/open-telemetry/opentelemetry-python/pull/4820))
