This release is API and ABI-compatible with the previous 3.2.x, meaning that
the existing applications don't even need to be rebuilt to profit from all the
fixes above if they use shared/dynamic libraries. And if they do need to be
recompiled, this can be done without any changes to the code.

We hope that you will enjoy using the new release!
