OSX support has not been promised for 2 years! Multiplicity itself has only been out just over a year!
It seems strange that you complain about us adding Vista support (which is important as we have customers who use the betas of Vista as well as internal staff who use MP when developing on Vista), yet then say Vista will be out soon.
I am curious to know what you expected from a minor point release update. Minor point releases are basically for fixes and minor tweaks.
Next on the development list is support for grid configurations and the OSX secondary support previously mentioned. If there is anything else in particular you are interested in, then please let us know.
