Changes in synapse v0.18.3 (2016-11-08) ======================================= SECURITY UPDATE Explicitly require authentication when using LDAP3. This is the default on versions of ``ldap3`` above 1.0, but some distributions will package an older version. If you are using LDAP3 login and have a version of ``ldap3`` older than 1.0 it is **CRITICAL to updgrade**.
