Sun is about to release Solaris under a new licence called CDDL.

It is based on MPL 1.1. The differences are listed here: http://www.sun.com/cddl/CDDL_MPL_redline.pdf

A summary can be found at http://www.sun.com/cddl/CDDL_why_details.html

I'm writing an article about it, and I would appreciate it if you could tell me whether CDDL is compatible with GPL and LGPL. In addition, I would like to understand whether a document released under CDDL would be compatible with documentation under GFDL.

There's also patently clear patent problems. There's a detailed analysis at Groklaw:

I'm personally inclined to avoid as much CDDL as possible, as it is of right now. Yes, even *use* of such Free Software, specially if it comes from Sun.
