ChangeLog

0.12.4 (2016-08-19):
  - Fix for issue 44: missing preserve_quotes keyword argument (reported
    by M. Crusoe)

0.12.3 (2016-08-17):
  - correct 'in' operation for merged CommentedMaps in round-trip mode
    (implementation inspired by J.Ngo, but original not working for merges)
  - iteration over round-trip loaded mappings, that contain merges. Also
    keys(), items(), values() (Py3/Py2) and iterkeys(), iteritems(),
    itervalues(), viewkeys(), viewitems(), viewvalues() (Py2)
  - reuse of anchor name now generates warning, not an error. Round-tripping such
    anchors works correctly. This inherited PyYAML issue was brought to attention
    by G. Coddut (and was long standing https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=515634)
    suppressing the warning:
        import warnings
        from ruamel.yaml.error import ReusedAnchorWarning
        warnings.simplefilter("ignore", ReusedAnchorWarning)

0.12.2 (2016-08-16):
  - minor improvements based on feedback from M. Crusoe
    https://bitbucket.org/ruamel/yaml/issues/42/

0.12.0 (2016-08-16):
  - drop support for Python 2.6
  - include initial Type information (inspired by M. Crusoe)

0.11.15 (2016-08-07):
  - Change to prevent FutureWarning in NumPy, as reported by tgehring
  ("comparison to None will result in an elementwise object comparison in the future")

0.11.14 (2016-07-06):
  - fix preserve_quotes missing on original Loaders (as reported
    by Leynos, bitbucket issue 38)

0.11.13 (2016-07-06):
  - documentation only, automated linux wheels

0.11.12 (2016-07-06):
  - added support for roundtrip of single/double quoted scalars using:
    ruamel.yaml.round_trip_load(stream, preserve_quotes=True)

0.11.0 (2016-02-18):
  - RoundTripLoader loads 1.2 by default (no sexagesimals, 012 octals nor
    yes/no/on/off booleans
