I'm pleased to announce the release of PyDO-2.0rc1.

What's New ----------

* If you pass in a module via the new "module" keyword argument of the project() method of PyDO objects and the autoschema function, the dynamically generated classes generated will be associated with that module so it can be pickled and unpickled. * 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 unconstraining.

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 pool.

* 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.

PyDO is dual GPL/BSD licensed.
