* Finally fixed performance issue[54](https://github.com/applegrew/django-select2/issues/54) (and issue[41](https://github.com/applegrew/django-select2/issues/41)) in widgets when backing field is based on models and the field has an initial value.

* Updated Select2 to version 3.4.2. **Please note**, that if you need any of the Select2 locale files, then you need to download them yourself from http://ivaynberg.github.com/select2/ and add to your project.
* Tagging support added. See [Field API reference](http://django-select2.readthedocs.org/en/latest/ref_fields.html) in documentation.

* Updated Select2 to version 3.4.1. **Please note**, that if you need any of the Select2 locale files, then you need to download them yourself from http://ivaynberg.github.com/select2/ and add to your project.
* Address isssue[36](https://github.com/applegrew/django-select2/issues/36) - Fix importerror under django1.6.
* Fixed the way `setup.py` handles Unicode files while minifying them during package build.
* Address isssue[39](https://github.com/applegrew/django-select2/issues/39) - MultipleSelect2HiddenInput.render() should use mark_safe().
* Address isssue[45](https://github.com/applegrew/django-select2/issues/45) - MultipleSelect2HiddenInput returns bad has_changed value.

* Main version number bumped to bring your attention to the fact that the default Id generation scheme has now changed. Now Django Select2 will use hashed paths of fields to generate their Ids. The old scheme of generating random Ids are still there. You can enable that by setting `GENERATE_RANDOM_SELECT2_ID` to `True`.
