ANNOUNCE: Rose::DB::Object 0.50 released

RDBO has been bumped to the big 0.50. (Hey, that's half way to 1.0, right?
:) There have been many changes (bug fixes and significant new features)
since the last announcement to this list. The full change summary is below.
The most significant change is probably the addition of an extensive
tutorial:

perldoc Rose::DB::Object::Tutorial

It's not a replacement for the reference-style documentation, but it does
give a nice overview of the major features, and how best to use them.

0.078 (10.24.2005) - John Siracusa

* Added "distinct" and "fetch_only" manager parameters.
* Added support for foreign key and relationship names as
column prefixes in manager query parameters and sort_by

* Fixed a bug that caused make_methods() to fail for "... to one"
relationships that have no corresponding foreign key.
* Fixed a bug in QueryBuilder that prevented the ability to check
for null columns.
* Added the ability to query columns that are not SELECTed.

0.076 (10.05.2005) - John Siracusa

* Fixed a bug that caused incorrect counts in get_objects_count()
when using the require_object parameter with "... to many"
relationships.

* Added cascaded delete, plus a plea in the documentation for users
to do this in the database instead.

* Added *_now and *_on_save method types for foreign keys and
"... to one" relationships.
* Made get_set_on_save and delete_on_save the default auto method
types for foreign keys and "... to one" relationships.
* load() now returns the object itself on success, which allows
for the convenient $obj = MyObject->new(id => 123)->load;
* save() now returns the object itself on success, which allows
for the convenient $obj = MyObject->new(id => 123)->save;
