The API breaking changes:

Removing String and Pretty.
Removing String from Path interface.

In which section of the migration docs should we mention them?

I had to keep the interface because there was an import cycle between 02-client and 23-commitment, if I tried to use commitmenttypes.MerklePath as the type for path in the Verify(Non)Membership functions of the client state interface.

I removed this so that the proto compiler generated an implementation of String because that is needed when we do this.

I think the linked test should be updated to use a valid path for misbehaviour. A marshaled merkle path is not an expected singing path for solomachines

It turns out that we might need to remove this because of this and this (why would we require the path to be proto-marshalled when submitting misbehaviour?).

Allowing it to be proto marshaled makes sense to me, but solo machine should not be proto marshaling the path when submitting misbeahviour, I think that might be a bug

Looks good! But we should not be referencing merkle path in solo machines anymore for testing. We should directly use the 24-host path

we should be removing merkle path usage in solo machines

True! I will do that!

Is this going to be fixed in a followup?

I cannot change this one because we require at the moment the path to be a proto-marshalled MerklePath when submitting misbehaviour. I will open an issue for this.

@colin-axner I implemented the feedback, but there's one thing I couldn't change and left a question in one of your comments

LGTM, is there an issue for the misbehaviour unmarshaling fix?

-	require.Equal(t, "", zeroPath.Pretty(), "zero element path does not have correct pretty string representation")
+	require.Len(t, prefixedPath.GetKeyPath(), 2, "unexpected key path length")


should this test be asserting what each element is in the key path?
