Subject: [ANN] PyYAML-3.06: YAML parser and emitter for Python

 Announcing PyYAML-3.06

A new bug fix release of PyYAML is now available:


* 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'
* 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__'.

About PyYAML

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.
