This book is based on Celtx Version 2.7. On February 8, 2011-as this book was receiving its final edits-Celtx 2.9 was released.
The only major difference between 2.7 and 2.9 is the renaming of Text to Novel. There were also 22 Bug Fixes and improvements (see http://www.celtx.com/#/desktop/nav-releasenotes for the complete list).
None of these changes make this book any less timely or useful. All of the suggested uses for Text, such as in outlining screenplays in Chapter 7 and marketing uses in Chapter 12, still work exactly the same in Novel.
Novel is essentially Text with Index Cards and Title Page included, both of which are covered in this book. Thus we can proudly state: Celtx: Open Source Screenwriting explains and enhances Celtx 2.7, 2.9, and future releases with valuable screenplay and other marketing tips found in no other book.
