- Implement `Default` on `Map` (not just on `RawMap`)
+- Worked around the spurious `where_clauses_object_safety` future-compatibility lint that has been raised since mid-2018.
+ If you put `#![allow(where_clauses_object_safety)]` on your binary crates for this reason, you can remove it.

I don’t plan for there to be any real changes from 0.12.1;
it should be just a bit of housecleaning and a version bump.
