/dev/null +++ b/CHANGES @@ -0,0 +1,140 @@ + +For a complete Subversion changelog, see 'http://pyyaml.org/log/pyyaml'. + +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 >> 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: +'http://lists.sourceforge.net/lists/listinfo/yaml-core'. + +Submit bug reports and feature requests to the PyYAML bug tracker: +'http://pyyaml.org/newticket?component=pyyaml'. + +PyYAML is written by Kirill Simonov .
