It's back again:

"Aladdin4D is going Shared-Source! This will provide faster updates & new features
[...]
Aladdin 4D 6.0 will work native on the platforms listed below.
OS X Mountain Lion
iPad
Amiga OS 4.x
MorphOS 3.x
Linux
AROS
[...]
Aladdin 4D 6.0 Stable Release 6.0.0.26 (Internal Beta) / Janurary 17th, 2013."

Also:

"In an effort to renew development efforts for Aladdin4D we will be making it shared-source commercial software. What this means is source code to Aladdin4D 5.x & 6.0 will be shared with key programmers in the AROS, AmigaOS 4 & MorphOS communities. Money will be paid out to any major changes they make to the code for example adding a MUI interface, native MorphOS or AmigaOS 4 version. completing Aladdin 4D 6.0 for OS X Etc. [...] When DiscreetFX acquired Aladdin4D the dream was to have a modern maintained beginners 3D animation/rendering package for AmigaOS,MorphOS & AROS. Hopefully the shared-source initiative can make that dream come alive."

"This shared-source initiative should help AmigaOS/MorphOS/AROS programmers and no longer benefit those only pretending to do the work and not even on AmigaOS."
