So Adobe has finally released the latest update for InDesign CS4 (6.0.2).
Basically, before this update was released, the ePub export functionality was broken.

Here is the latest blog post from Adobe about the update:

With this update, I am happy to report, that most of the major issues have indeed been fixed. More importantly, Adobe has also made major improvements to how ePub was exported in CS3. It is that much closer now to being able to generate "valid" ePub right out of InDesign CS4.

With that said, we still have a ways to go.

For example:

• The encryption.xml file that can be found in the META-INF directory in the finished ePub file. This file does not seem to have a real purpose and if removed, does not seem to affect the ePub in any way. I would like to see Abobe get rid of this.


• Some refining needs to be done to the figure optimization settings. They are not terrible, but this could be much better.


• Font handling and embedding needs to be improved.


• I am finding some bugs with cross-references being translated to ePub hyperlinks.

More to come . . .
