PyDO-2.0a1 released

[Jacob Smullyan]

I'm pleased to announce the second alpha release of PyDO 2.


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

* PyDO2 is now in the PyDO2 package, to facilitate peaceful
  coexistence with PyDO1.

* explicit schema support (as in 'myschema.mytable').

* The "table" attribute can now be left out if the class name
  is the name of the table.

* "refetch" behavior has been refactored.

* there are a bunch of classes to help in doing various kinds of
  joins.

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.

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

It also has several limitations:

   * PyDO 2 is alpha code.  Bugs should be expected, and the API is not
     guaranteed to be stable.

   * Currently, PyDO 2 supports fewer database systems than PyDO 1
     (PostgreSQL, SQLite, and MySQL), although adding new drivers
     should not be difficult.

   * PyDO 2 requires Python 2.4 or later.

PyDO is dual GPL/BSD licensed.
