Here’s hoping that this update helps fix some of the issues we’ve been having with Flash CS4.  I can’t tell you how many opportunities I have given CS4 on my projects only to find myself reverting back to CS3 mid-way through the project.  Flash CS4 10.0.2 boasts a large number of bug fixes and performance increases.  Adobe says:

This update for Flash CS4 Professional (10.0.2) addresses issues related to compiling large projects. Specifically, it addresses stability and performance issues related to large animation files, such as timeline scrubbing and looping and nested movie clips, as well as text handling. For more details, read the technote. For more about this update from Richard Galvan, product manager for Adobe Flash Professional, visit Richard Galvan’s blog.

As mentioned above, Richard Galvan’s blog lists a huge number of fixes at the bottom of this blog post.
