Yannick Gaultier just released the sh404SEF version 1.3 RC . This version co-operates nicely with the Joom!Fish 1.8 extension and we can highly recommend using this combination for your SEF integrations. SH404SEF is also used on our own sites where we are testing several combinations of tools. It works since the beginning and since Yannick joined the Joom!Fish tech-talk team we have been able to improve the co-operation of both extensions nicely.
