Object::Transaction is now in production use.

The underlying object is no longer locked during loading. If you have a preload() method, be aware that the object is no longer locked during the preload() call.

The new() method is no longer something to override. It has been replaced with initialize(). If you had a new method, that's okay, but make sure to call cache() from within it.

Objects may now move during transactions. If the file() method returns something different than it did before the transaction, the object will be moved. It used to crash.

Method invocations like C<presave()> may how have side-effects that effect the transaction like invoking C<savelater()> an another object.

To create a reference to a persisted object, a new method is provided: ->objectref(). This can be turned into an object with ->loadref().

When used with mod_perl, the object cache will be automatically cleared each web hit.

Added otedit & otview.

Many bugs fixed.
