v3.2.1

The upcoming v4 release will introduce breaking changes. As always, it is
recommended to thoroughly review and test the upgrade procedure in a
non-production environment.

Unfortunately, a few issues popped up in ADF v3.2.0 that block a clean
installation in a new environment. Making it harder to test the upgrade
process. This release resolves those issues and includes an updated installer
for ADF to simplify installation.

We hope this shortens the time required to prepare for the v4 upgrade.
