Yes, we made the switch in Tails 1.2.1, although the old configuration
should have worked until Tails 1.2.3. In Tails 1.3 we removed Polipo
completely, so since then the old configuration wouldn't work at all.

So far we've been documenting required steps in the release notes. For
instance, for this particular change we had this:

    https://tails.boum.org/news/version_1.2.1/#index3h1


It's true that this puts a lot of responsibility on the users. An
automated way to detect changes in a persistent configuration that
probably should be changed + easy UX for users to decide would be nice,
perhaps something like Debian Conffile diff handling when updating a
package (but with a GUI) would do. However, automatically detecting such
changes doesn't look easy at first glance, but proposals for how it can
be done reliably are welcome. :)

Cheers!
