------------------

* Make version check in register compatible with prereleases.

no database commit was required.

See: https://github.com/zopefoundation/zope.sqlalchemy/issues/8

------------------

* Allow ``session.commit()`` on nested transactions to facilitate integration
of existing code that might not use ``transaction.savepoint()``.

See: https://github.com/zopefoundation/zope.sqlalchemy/issues/1

* Add a new function zope.sqlalchemy.register(), which replaces the
direct use of ZopeTransactionExtension to make use
of the newer SQLAlchemy event system to establish instrumentation on
the given Session instance/class/factory. Requires at least
SQLAlchemy 0.7.

See: https://github.com/zopefoundation/zope.sqlalchemy/issues/4

* Fix `keep_session=True` doesn't work when a transaction is joined by flush
and other manngers bug.
