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__'.
- assume that Python 2.4 and 2.5 are compatible and allow checking for
fallout.
- remove PYTHON_VERSIONS_COMPATIBLE that are obsoleted by the 2.3+
default. Modify the others to deal with the removals.
3.05 (2007-05-13)
* Allow for immutable subclasses of YAMLObject. Fixed#53.
* Make the encoding of the unicode->str conversion explicit; fixed#52.
* Fixed a problem when the DOCUMENT-END event is not emitted until
the beginning of the next document is available. Fixed#51. Thanks
edward(at)sweetbytes.net for the bug report.
* Improve output of float values. Fixed#49.
* Fix the bug when the path in add_path_resolver contains boolean
values. Fixed#43 (thanks to jstroud(at)mbi.ucla.edu for reporting
and pointing to the cause).
* Use the types module instead of constructing type objects by
hand. Fixed#41. Thanks to v.haisman(at)sh.cvut.cz for the patch.
* Fix loss of microsecond precision in datetime.datetime constructor
(fix#30). Thanks to edemaine(at)mit.edu for the bug report and the patch.
* Fixed loading an empty YAML stream.
3.04 (2006-08-20)
* Include experimental LibYAML bindings.
* Fully support recursive structures (close#5).
* Sort dictionary keys (close#23). Mapping node values are now
represented as lists of pairs instead of dictionaries. Do not
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
(close#17).
* To make porting easier, rewrite Parser not using generators.
* Fix handling of unexpected block mapping values, like
: foo
* 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 (close#22).
* Make Representer not try to guess !!pairs when a list is represented.
* Fix timestamp constructing and representing (close#25).
* Fix the 'N' plain scalar being incorrectly recognized as !!bool (close#26).
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.
