The NEWS file lists the features that were added in each version.
Most notably in 4.0 I see a couple of improvements to the autocompletion infrastructure, the (optional) addition of the ** glob operator, associative arrays and various syntactic shortcuts.

Also theautocdoption — it doesn't look like much, but as a zsh user, it's what I miss most when I occasionally use bash (<4 or unconfigured).
