# 1.0.2 to 1.0.x-dev Most occurences of "listener" have been replaced with "subscriber" to honor a subtle difference between the two that is explained [in the documentation](http://doctrine-orm.readthedocs.org/en/latest/reference/events.html#listening-and-subscribing-to-lifecycle-events). If you use translatable, you should map your translation classes `id` fields, the `id` mapping is deprecated and will be removed in version 2.0 If you decided to create your own subscriber by extending a class from this library, you might have to refactor your code because of this. Likewise, DI parameters (for class names), and service ids have changed.
