+++++
**Features**
- Improved performances on big files deserialization (2x faster). This new
version relies on descriptor instead of ``__getattribute__/__setattr__``.
The code is not more compact, but more clear and split.
- New static metamodel generator, producing code related to this new version.
- Add XML type transtyping in the static metamodel generator.
**Bugfixes**
- When an ``eOpposite`` feature was set on an element, the actual opposite
reference ``eOpposite`` was not updated.
- Subpackages managements for the static metamodel generator. The
``eSubpackages`` and ``eSuperPackage`` variables were not placed in the
package, but in the module.
**Miscellaneous**
- Update bad examples in the README.rst
