LightWave 7.5c available for download
 

I've not tried it yet (downloading now), but the word on the web is that this appears to be a very stable release. Also, the Mac version is now in sync with the Windows version regarding the available plug-ins.

However, Mac users should note that the three plugs that were missing from 7.5b need to be manually added to the menus for 7.5c (apparently).
