-For a complete Mercurial changelog, see
-'https://bitbucket.org/xi/pyyaml/commits'.
-
-3.11 (2014-03-26)
------------------
-
-* Source and binary distributions are rebuilt against the latest
-  versions of Cython and LibYAML.
-
-3.10 (2011-05-30)
------------------
-
-* Do not try to build LibYAML bindings on platforms other than CPython
-  (Thank to olt(at)bogosoft(dot)com).
-* Clear cyclic references in the parser and the emitter
-  (Thank to kristjan(at)ccpgames(dot)com).
-* Dropped support for Python 2.3 and 2.4.
-
-3.09 (2009-08-31)
------------------
-
-* Fixed an obscure scanner error not reported when there is
-  no line break at the end of the stream (Thank to Ingy).
-* Fixed use of uninitialized memory when emitting anchors with
-  LibYAML bindings (Thank to cegner(at)yahoo-inc(dot)com).
-* Fixed emitting incorrect BOM characters for UTF-16 (Thank to
-  Valentin Nechayev)
-* Fixed the emitter for folded scalars not respecting the preferred
-  line width (Thank to Ingy).
-* Fixed a subtle ordering issue with emitting '%TAG' directives
-  (Thank to Andrey Somov).
-* Fixed performance regression with LibYAML bindings.
-
-
-3.08 (2008-12-31)
------------------
-
-* Python 3 support (Thank to Erick Tryzelaar).
-* Use Cython instead of Pyrex to build LibYAML bindings.
-* Refactored support for unicode and byte input/output streams.
-
-
-3.07 (2008-12-29)
------------------
-
-* The emitter learned to use an optional indentation indicator
-  for block scalar; thus scalars with leading whitespaces
-  could now be represented in a literal or folded style.
-* The test suite is now included in the source distribution.
-  To run the tests, type 'python setup.py test'.
-* Refactored the test suite: dropped unittest in favor of
-  a custom test appliance.
-* Fixed the path resolver in CDumper.
-* Forced an explicit document end indicator when there is
-  a possibility of parsing ambiguity.
-* More setup.py improvements: the package should be usable
-  when any combination of setuptools, Pyrex and LibYAML
-  is installed.
-* Windows binary packages are built against LibYAML-0.1.2.
-* Minor typos and corrections (Thank to Ingy dot Net
-  and Andrey Somov).
-
-
-3.06 (2008-10-03)
------------------
-
-* setup.py checks whether LibYAML is installed and if so, builds
-  and installs LibYAML bindings.  To force or disable installation
-  of LibYAML bindings, use '--with-libyaml' or '--without-libyaml'
-  respectively.
-* The source distribution includes compiled Pyrex sources so
-  building LibYAML bindings no longer requires Pyrex installed.
-* 'yaml.load()' raises an exception if the input stream contains
-  more than one YAML document.
-* Fixed exceptions produced by LibYAML bindings.
-* Fixed a dot '.' character being recognized as !!float.
-* Fixed Python 2.3 compatibility issue in constructing !!timestamp values.
-* Windows binary packages are built against the LibYAML stable branch.
-* Added attributes 'yaml.__version__' and  'yaml.__with_libyaml__'.
-
-
-3.05 (2007-05-13)
------------------
-
-* Windows binary packages were built with LibYAML trunk.
-* Fixed a bug that prevent processing a live stream of YAML documents in
-  timely manner (Thanks edward(at)sweetbytes(dot)net).
-* Fixed a bug when the path in add_path_resolver contains boolean values
-  (Thanks jstroud(at)mbi(dot)ucla(dot)edu).
-* Fixed loss of microsecond precision in timestamps
-  (Thanks edemaine(at)mit(dot)edu).
-* Fixed loading an empty YAML stream.
-* Allowed immutable subclasses of YAMLObject.
-* Made the encoding of the unicode->str conversion explicit so that
-  the conversion does not depend on the default Python encoding.
-* Forced emitting float values in a YAML compatible form.
-
-
-3.04 (2006-08-20)
------------------
-
-* Include experimental LibYAML bindings.
-* Fully support recursive structures.
-* Sort dictionary keys.  Mapping node values are now represented
-  as lists of pairs instead of dictionaries.  No longer check
-  for duplicate mapping keys as it didn't work correctly anyway.
-* Fix invalid output of single-quoted scalars in cases when a single
-  quote is not escaped when preceeded by whitespaces or line breaks.
-* To make porting easier, rewrite Parser not using generators.
-* Fix handling of unexpected block mapping values.
-* Fix a bug in Representer.represent_object: copy_reg.dispatch_table
-  was not correctly handled.
-* Fix a bug when a block scalar is incorrectly emitted in the simple
-  key context.
-* Hold references to the objects being represented.
-* Make Representer not try to guess !!pairs when a list is represented.
-* Fix timestamp constructing and representing.
-* Fix the 'N' plain scalar being incorrectly recognized as !!bool.
-
-
-3.03 (2006-06-19)
------------------
-
-* Fix Python 2.5 compatibility issues.
-* Fix numerous bugs in the float handling.
-* Fix scanning some ill-formed documents.
-* Other minor fixes.
-
-
-3.02 (2006-05-15)
------------------
-
-* Fix win32 installer.  Apparently bdist_wininst does not work well
-  under Linux.
-* Fix a bug in add_path_resolver.
-* Add the yaml-highlight example.  Try to run on a color terminal:
-  `python yaml_hl.py <any_document.yaml`.
-
-
-3.01 (2006-05-07)
------------------
-
-* Initial release.  The version number reflects the codename
-  of the project (PyYAML 3000) and differenciates it from
-  the abandoned PyYaml module.

-Description: YAML is a data serialization format designed for human readability
-        and interaction with scripting languages.  PyYAML is a YAML parser
-        and emitter for Python.
-        
-        PyYAML features a complete YAML 1.1 parser, Unicode support, pickle
-        support, capable extension API, and sensible error messages.  PyYAML
-        supports standard YAML tags and provides Python-specific tags that
-        allow to represent an arbitrary Python object.
-        
-        PyYAML is applicable for a broad range of tasks from complex
-        configuration files to object serialization and persistance.

-PyYAML - The next generation YAML parser and emitter for Python.
-
-To install, type 'python setup.py install'.
-
-By default, the setup.py script checks whether LibYAML is installed
-and if so, builds and installs LibYAML bindings.  To skip the check
-and force installation of LibYAML bindings, use the option '--with-libyaml':
-'python setup.py --with-libyaml install'.  To disable the check and
-skip building and installing LibYAML bindings, use '--without-libyaml':
-'python setup.py --without-libyaml install'.
-
-When LibYAML bindings are installed, you may use fast LibYAML-based
-parser and emitter as follows:
-
-    >>> yaml.load(stream, Loader=yaml.CLoader)
-    >>> yaml.dump(data, Dumper=yaml.CDumper)
-
-PyYAML includes a comprehensive test suite.  To run the tests,
-type 'python setup.py test'.
-
-For more information, check the PyYAML homepage:
-'http://pyyaml.org/wiki/PyYAML'.
-
-For PyYAML tutorial and reference, see:
-'http://pyyaml.org/wiki/PyYAMLDocumentation'.

-Post your questions and opinions to the YAML-Core mailing list:
