<SettingsInfoBlock type="Bool" default_value="0" />

<VersionHistory rows={[{"id": "row-1","items": [{"label": "25.7"},{"label": "0"},{"label": "新增设置"}]}]} />

<div id="table_function_remote_max_addresses">
  ## table\_function\_remote\_max\_addresses
</div>

<SettingsInfoBlock type="UInt64" default_value="1000" />
