Under development now is adapting the whole of the hacks of M17n to Joomla 1.5.7. The current hacks are working, but all has to be checked against the Joomla 1.5.7 update.

Also, I have learned from SDIC, the makers of M17n that a new version of M17n is under development. More features?? Let's welcome the new version in advance! We are looking forward.
