I've added v3.1 to the above post. It turns out that trying to avoid one KePub problem just causes another.

* v3 is probably better for those who read KePubs with very narrow line spacing.

* v3.1 is probably better for those who read KePubs with a large font size.

Either version is fine for reading ePubs.

Edit: The only difference between v3 and v3.1 is the HHead ascent/descent offsets. If you want to play with them in fontforge you might be able to find a setting that works better for you. Increasing both offsets improves the split problem and worsens the clip problem, decreasing both offsets does the opposite.
