across different versions of Python. 127* Fixed comparison to None warning. 128 1293.11 (2014-03-26) 130----------------- 131 132* Source and binary distributions are rebuilt against the latest 133 versions of Cython and LibYAML. 134 1353.10 (2011-05-30) 136----------------- 137 138* Do not try to build LibYAML bindings on platforms other than CPython 139 (Thank to olt(at)bogosoft(dot)com). 140* Clear cyclic references in the parser and the emitter 141 (Thank to kristjan(at)ccpgames(dot)com). 142* Dropped support for Python 2.3 and 2.4. 143 1443.09 (2009-08-31) 145----------------- 146 147* Fixed an obscure scanner error not reported when there is 148 no line break at the end of the stream (Thank to Ingy). 149* Fixed use of uninitialized memory when emitting anchors with 150 LibYAML bindings (Thank to cegner(at)yahoo-inc(dot)com). 151* Fixed emitting incorrect BOM characters for UTF-16 (Thank to 152 Valentin Nechayev) 153* Fixed the emitter for folded scalars not respecting the preferred 154 line width (Thank to Ingy). 155* Fixed a subtle ordering issue with emitting '%TAG' directives 156 (Thank to Andrey Somov). 157* Fixed performance regression with LibYAML bindings. 158 159 1603.08 (2008-12-31) 161----------------- 162 163* Python 3 support (Thank to Erick Tryzelaar). 164* Use Cython instead of Pyrex to build LibYAML bindings. 165* Refactored support for unicode and byte input/output streams. 166 167 1683.07 (2008-12-29) 169----------------- 170 171* The emitter learned to use an optional indentation indicator 172 for block scalar; thus scalars with leading whitespaces 173 could now be represented in a literal or folded style. 174* The test suite is now included in the source distribution. 175 To run the tests, type 'python setup.py test'. 176* Refactored the test suite: dropped unittest in favor of 177 a custom test appliance. 178* Fixed the path resolver in CDumper. 179* Forced an explicit document end indicator when there is 180 a possibility of parsing ambiguity. 181* More setup.py improvements: the package should be usable 182 when any combination of setuptools, Pyrex and LibYAML 183 is installed. 184* Windows binary packages are built against LibYAML-0.1.2. 185* Minor typos and corrections (Thank to Ingy dot Net 186 and Andrey Somov). 187 188 1893.06 (2008-10-03) 190----------------- 191 192* setup.py checks whether LibYAML is installed and if so, builds 193 and installs LibYAML bindings. To force or disable installation 194 of LibYAML bindings, use '--with-libyaml' or '--without-libyaml' 195 respectively. 196* The source distribution includes compiled Pyrex sources so 197 building LibYAML bindings no longer requires Pyrex installed. 198* 'yaml.load()' raises an exception if the input stream contains 199 more than one YAML document. 200* Fixed exceptions produced by LibYAML bindings. 201* Fixed a dot '.' character being recognized as !!float. 202* Fixed Python 2.3 compatibility issue in constructing !!timestamp values. 203* Windows binary packages are built against the LibYAML stable branch. 204* Added attributes 'yaml.__version__' and 'yaml.__with_libyaml__'. 205 206 2073.05 (2007-05-13) 208----------------- 209 210* Windows binary packages were built with LibYAML trunk. 211* Fixed a bug that prevent processing a live stream of YAML documents in 212 timely manner (Thanks edward(at)sweetbytes(dot)net). 213* Fixed a bug when the path in add_path_resolver contains boolean values 214 (Thanks jstroud(at)mbi(dot)ucla(dot)edu). 215* Fixed loss of microsecond precision in timestamps 216 (Thanks edemaine(at)mit(dot)edu). 217* Fixed loading an empty YAML stream. 218* Allowed immutable subclasses of YAMLObject. 219* Made the encoding of the unicode->str conversion explicit so that 220 the conversion does not depend on the default Python encoding. 221* Forced emitting float values in a YAML compatible form. 222 223 2243.04 (2006-08-20) 225----------------- 226 227* Include experimental LibYAML bindings. 228* Fully support recursive structures. 229* Sort dictionary keys. Mapping node values are now represented 230 as lists of pairs instead of dictionaries. No longer check 231 for duplicate mapping keys as it didn't work correctly anyway. 232* Fix invalid output of single-quoted scalars in cases when a single 233 quote is not escaped when preceded by whitespaces or line breaks. 234* To make porting easier, rewrite Parser not using generators. 235* Fix handling of unexpected block mapping values. 236* Fix a bug in Representer.represent_object: copy_reg.dispatch_table 237 was not correctly handled. 238* Fix a bug when a block scalar is incorrectly emitted in the simple 239 key context. 240* Hold references to the objects being represented. 241* Make Representer not try to guess !!pairs when a list is represented. 242* Fix timestamp constructing and representing. 243* Fix the 'N' plain scalar being incorrectly recognized as !!bool. 244 245 2463.03 (2006-06-19) 247----------------- 248 249* Fix Python 2.5 compatibility issues. 250* Fix numerous bugs in the float handling. 251* Fix scanning some ill-formed documents. 252* Other minor fixes. 253 254 2553.02 (2006-05-15) 256----------------- 257 258* Fix win32 installer. Apparently bdist_wininst does not work well 259 under Linux. 260* Fix a bug in add_path_resolver. 261* Add the yaml-highlight example. Try to run on a color terminal: 262 `python yaml_hl.py <any_document.yaml`. 263 264 2653.01 (2006-05-07) 266----------------- 267 268* Initial release. The version number reflects the codename 269 of the project (PyYAML 3000) and differentiates it from 270 the abandoned PyYaml module. 271 272
