-Migrating from 0.x to 1.x
--------------------------
-
-The only major change from 0.x releases and 1.x is the underlying LDAP library changed from python-ldap to
-[pyldap](https://github.com/pyldap/pyldap) which is fork that adds Python 3.x support. Everything else **SHOULD**
-be the same, but don't hesitate to open an issue if you encounter some problem upgrading from 0.x to 1.x.
