 """Decode this BSON data. By default, returns a BSON document represented as a Python :class:`dict`. To use a different :class:`MutableMapping` class, configure a :class:`~bson.codec_options.CodecOptions`:: <type 'dict'> <class 'collections.OrderedDict'> :Parameters: - `codec_options` (optional):
 An instance of :class:`~bson.codec_options.CodecOptions`. .. versionchanged:: 3.0 Removed `compile_re` option: PyMongo now always represents BSON regular expressions as :class:`~bson.regex.Regex` objects. Use :meth:`~bson.regex.Regex.try_compile` to attempt to convert from a BSON regular expression to a Python regular expression object. Replaced `as_class`, `tz_aware`, and `uuid_subtype` options with `codec_options`. .. versionchanged:: 2.7 Added `compile_re` option. If set to False, PyMongo represented BSON regular expressions as :class:`~bson.regex.Regex` objects instead of attempting to compile BSON regular expressions as Python native regular expressions, thus preventing errors for some incompatible patterns, see `PYTHON-500`_. .. _PYTHON-500: https://jira.mongodb.org/browse/PYTHON-500 """
