Storyist Software, a developer of creative writing tools for Mac OS X, has updated Storyist, a story development tool for novelists and screenwriters, to version 2.2.1. It’s a maintenance release with some bug fixes and performance tweaks.

Storyist provides a word processor with the features writers expect from a top-notch writing program, including spelling and grammar checking and a page layout view with support for headers, footers, and style sheets. It also provides a number of features not found in typical word processing applications and screenplay formatters.

Storyist 2.2.1 is compatible with Mac OS X 10.4.11 and higher. The download-only version is $59 and a download + boxed set (CD + printed manual) version is $79. Both are available through the company’s online store (http://www.storyist.com/store).
