Version 2.0.0 of the LyX document processing system is out. "With this release, LyX celebrates 15 years of existence, and we start a new family of 2.x releases to acknowledge LyX's passing from a child to an adult. We hope you will celebrate this anniversary with us." There are many new features in this release; see the "what is new" page and LWN's LyX 2.0 review for more information.
