Subject: [ANN] PyYAML-3.08: Now with Python 3 support

 Announcing PyYAML-3.08

A new release of PyYAML is now available:

This release features a complete support for Python 3.  For
compatibility notes between Python 2 and Python 3 versions,
please see


* Python 3 support (Thank to Erick Tryzelaar).
* Use Cython instead of Pyrex to build LibYAML bindings.  Note
  that the source package is distributed with a pre-generated
  '_yaml.c' file so you don't need Cython installed to build
  LibYAML bindings.
* Refactored support for unicode and byte input/output streams.

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.
