I'm pleased to announce the release of PyDO-2.0b2.

What's New

* the project() method now takes the keyword argument "mutable", which 
  overrides the mutability of the base class.
* new, more declarativeshortcuts for defining associations between 
  tables: ForeignKey, OneToMany, and ManyToMany.
* several bugfixes, with corresponding tests.
What it is

PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access
library for Python that facilitates writing a Python database access
layer.  PyDO attempts to be simple, flexible, extensible, and

PyDO 2 is a rewrite of the 1.x series distributed with SkunkWeb.
It has several enhancements:

   * PyDO can now be used in multi-threaded or twisted-style
     asynchronous sitations, with or without a customizable connection

   * PyDO objects are now dict subclasses, but also support attribute
     access to fields.

   * Projections -- subsets of the field list of a super-class -- are
     now supported by the PyDO.project() method.

   * Table attributes are now declared in a more concise way.

   * PyDO2 supports runtime table introspection.

   * Overall, the API has been tightened and the code restructured.

PyDO 2 requires Python 2.4 or later.  It currently supports
PostgreSQL, MySQL, Sqlite, MSSQL, and Oracle, and support for other
databases is planned.

PyDO is dual GPL/BSD licensed.
