A while ago I blogged about uselessness of djvu format under MacOS X.
New version, 6.0, of djvu software came out, that actually has a functional DjVu Plugin Host.app. Now I can look at Penthouse and Playboy issues again. Or at least at issues of “Junyj Technik” from 80s.
Still no reasonable way to convert the format to other formats, though.
