ChangeLog

0.12.18 (2016-11-16):
 - another fix for numpy (re-reported by Nathanial Burdic)

0.12.17 (2016-11-15):
 - only the RoundTripLoader included the Resolver that supports YAML 1.2
   now all loaders do (reported by mixmastamyk)

0.12.16 (2016-11-13):
 - allow dot char (and many others) in anchor name
   Fix issue 72 (reported by Shalon Wood)
 - Slightly smarter behaviour dumping strings when no style is
   specified. Single string scalars that start with single quotes
   or have newlines now are dumped double quoted: "'abc\nklm'" instead of
   '''abc

      klm'''

0.12.14 (2016-09-21):
 - preserve round-trip sequences that are mapping keys
   (prompted by stackoverflow question 39595807 from Nowox)

0.12.13 (2016-09-15):
 - Fix for issue #60 representation of CommentedMap with merge
   keys incorrect (reported by Tal Liron)

0.12.11 (2016-09-06):
 - Fix issue 58 endless loop in scanning tokens (reported by
   Christopher Lambert)

0.12.10 (2016-09-05):
 - Make previous fix depend on unicode char width (32 bit unicode support
   is a problem on MacOS reported by David Tagatac)

0.12.8 (2016-09-05):
   - To be ignored Unicode characters were not properly regex matched
     (no specific tests, PR by Haraguroicha Hsu)

0.12.7 (2016-09-03):
   - fixing issue 54 empty lines with spaces (reported by Alex Harvey)

0.12.6 (2016-09-03):
   - fixing issue 46 empty lines between top-level keys were gobbled (but
     not between sequence elements, nor between keys in netsted mappings
     (reported by Alex Harvey)

0.12.5 (2016-08-20):
  - fixing issue 45 preserving datetime formatting (submitted by altuin)
    Several formatting parameters are preserved with some normalisation:
    - preserve 'T', 't' is replaced by 'T', multiple spaces between date
      and time reduced to one.
    - optional space before timezone is removed
    - still using microseconds, but now rounded (.1234567 -> .123457)
    - Z/-5/+01:00 preserved

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
