- EngineCreatedEvent also gets ``engine_args`` and ``engine_kw`` as attributes, so that event handlers can potentially differentiate between engines.
0.11
=================
- Add pool_size, max_overflow, pool_recycle and pool_timeout options to the <engine /> directive. This allows connection pooling options to be defined in ZCML.
- works with sqlalchemy >= 0.5 (wouldn't work with sqlalchemy > 5 prior)
0.10
=================
- Support current ZTK code
- engine.echo must default to None for SQLAlchemy to honor logging.getLogger("sqlalchemy.engine").setLevel(...)
- Do not enable convert_unicode by default. This option changes standard SQLAlchemy behaviour by making String type columns return unicode data. This can be especially painful in Zope2 environments where unicode is not always accepted.
- Add a convert_unicode option to the zcml engine statement, allowing people who need convert_unicode to enable it.
