After a long, long wait I have released Lightbox Plus to version 2.3. It should show up in updates pretty soon if not already. Unfortunately it’s a relatively minor update though it does add some additional functionality both on the WordPress side (up to 100 inline lightboxes are available) but also a variety of changes with ColorBox.
This update includes ColorBox version 1.3.17. I also fixed some minor internal bugs and some incorrect text. And finally I verified compatibility with WordPress 3.2.x.
