For a complete changelog, see https://github.com/yaml/pyyaml/commits/ 3.13 (2018-07-05) ----------------- * Rebuilt with the latest Cython to support the new Python 3.7 release. * No functionality is different from PyYAML 3.12 in this release. 3.12 (2016-08-28) ----------------- * Wheel packages for Windows binaries. * Adding an implicit resolver to a derived loader should not affect the base loader (fixes issue #57). * Uniform representation for OrderedDict across different versions of Python (fixes issue #61). * Fixed comparison to None warning (closes issue #64). 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
