-0.14.0
-******
-This release includes a few bug fixes and a significant code cleanup. The most
-important change is that `QuerySet.as_pymongo` no longer supports a
-`coerce_types` mode. If you used it in the past, a) please let us know of your
-use case, b) you'll need to override `as_pymongo` to get the desired outcome.
-
-This release also makes the EmbeddedDocument not hashable by default. If you
-use embedded documents in sets or dictionaries, you might have to override
-`__hash__` and implement a hashing logic specific to your use case. See #1528
-for the reason behind this change.
